King Eider - Avalon


I did a quick coastal run on Christmas Day, in particular to see the breeding plumaged male King Eider at Avalon. Avalon is most of the way down to Cape May (it's actually in Cape May Co) so it turned into a long loop trip.

A quick start at Barnegat Inlet turned up pretty much nothing in the inlet, relatively few Bonaparte's Gulls in the bay, so I decided not to rock hop 500 times to reach the end of the breakwater and headed south to Avalon.

At the 8th Street jetty there was an "Ipswich" Savannah Sparrow, a few close fly-by Gannets (one oiled, sadly), and a couple of loons. Not much to distract from the sea duck flock: Black and Surf Scoters in decent numbers, lots of Common Eiders and one King Eider. The King Eider was really in full-on breeding plumage - search Flickr to get an idea what I mean - although the orange plate at the forehead (base of the bill?) wasn't quite as large as it can get. All the King Eiders I've seen in recent years (2003+) have been the drab females including the two from this year, although my first few - Rhode Island, Montauk in 1999-2001 were all males.

On the way back I took a little spin around Brigantine/Forsythe NWR and saw a totally predictable set of species - raptor numbers down from earlier visits, Pintail numbers subsiding, but the Snow Goose flock was putting on a good show. Birds would feed out in the saltmarsh and then fly across the dike to the pool to bathe, then return to the saltmarsh. There was pretty much a constant stream of Snow Geese in the air. Being Greater Snow Geese there were very few "Blue" Goose color morphs (Lesser Snow Geese have proportionally more), and I didn't see a Ross's despite keeping my eye open for it.

Christmas Eve - Rufous Hummingbird and Dickcissel

Manhattan on the last shopping day before Christmas ? Madness. However I decided to take a little photo/birding trip into NYC in search of two rarities: Dickcissel and Rufous Hummingbird.

The Dickcissel was significant because I've seen very few Dickcissels in general (my first being one at Jones Beach in 2001), certainly not annually, although 2011 was a bumper year for them by comparison: one in FL; the ones at Negri-Nepote in late spring; singing birds in TX; and now this one. This Dickcissel was spending time in a large (30+) House Sparrow flock, as often is the way with Dickcissels. The flock was very skittish so it took a while to find the bird even though it had enough yellow (immature male) to stick out from the crowd once you found it. I saw a Dickcissel in Central Park in 2008, the only other one I saw in NYC.

Hummingbirds are another story: I've seen quite a few Rufous this year, mainly on the Pacific Northwest trip but also in Yonkers in November. A Yonkers Rufous Hummingbird in 2001 spawned my first web page and I've pursued a mini project of photographing NYC hummingbirds. This Rufous is an immature female and was found on December 14th. It's on the north side of the American Museum for Natural History - i.e. the cold side - with no direct sun but some reflected sun. Perhaps the micro-environment has kept the hardy plants flowering on which this Rufous is depending on for it's short-term survival. A lot of vagrant Rufous in this area make it into the first few days of January but disappear soon after, so I will try and see it again on Jan 1st.

Barnegat Inlet - epic

This Saturday I made no mistake about spending most of my time at Barnegat Inlet instead of pushing on elsewhere - I was out there for about 4 hours starting shortly after dawn. Fishermen abounded on both the breakwater and in small craft, so once more there was little in the inlet itself - a group of three White-winged Scoters hugging the breakwater (injured?) being the exceptions.

In the bay there was a flock of Bonaparte's Gulls with a few Laughing Gulls but no Forster's Terns this time - the cooling weather might have pushed them south. Out at the far (Atlantic) end of the breakwater there was an immense amount of activity out on the ocean. The entire time I was watching there were always Red-throated Loons at mid-altitude headed south in small loose flocks (max=14) which means there must have been pushing a thousand migrating during that time. There were also some at sea level. I saw all of two Common Loons. Sea ducks were also numerous - mostly in one huge mixed flock just south of the inlet; Common Eider; all three Scoters; Harlequin Duck; Long-tailed Duck. Eiders themselves numbered in the hundreds (one report from there logged it as 350). If you scoped further out into the ocean there were sea ducks further out as well (scoters, mainly) so there were one to a few thousand oceanic ducks milling around the area. Most of the inshore scoters appeared to be immature/female birds, with disproportionately few males but there seemed to be more males further out in the fairly strong swell off the breeze.

With the Red-throated Loon movement there was also a smaller Northern Gannet movement southward, always in small flocks and mostly adults or near-adults. There were also more flocks of Bonaparte's Gulls north of the inlet. And just as had been reported the previous weekend, this attracted the Parasitic Jaegers. The Jaegers were behaving as a combination of sea gull and Peregrine, hugging the ocean until they saw something they wanted to follow and then accelerating to chase it down - something that was quite visible even at range. Mostly it was the Bonaparte's Gulls but sometimes they chased each other. I had about 8 sightings, which could have been anywhere between two to eight actual individuals (one birder saw 4 at once). The sheer number of birds was impressive, but it was the Parasitics that were particularly special for me since I'd only added them to my life list (conservatively) in late summer. Now I've finally seen more Parasitics than any other Jaeger (I've seen 5 Long-tailed, for example) although none of the views were especially close.

Other birds included the typical four shorebirds: Sanderling; Dunlin; Ruddy Turnstone; Purple Sandpiper. Two Peregrines were soaring together over the breakwater. An unusual bird for Barnegat was a Northern Harrier, probably a late migrant headed south down the barrier beach. Passerine activity was minimal, a few Yellow-rumped and some standard suburban birds, all at the state park.


After Barnegat I did go again to Brigantine/Forsythe NWR but the results were identical to the previous weekend and not noteworthy.

Cackling Geese

I found singles of Cackling Geese at North Branch Park and Dukes Island Park in Raritan on Sunday morning amongst flocks of Canada Geese, as had previously been reported. I didn't find the Greater White-fronted Goose at Dukes Island (I was there before it was reported) but there were enough Canada Geese milling around in the air that it might have flown in after I left.

En route home for this short birding day I stopped at the Stony Brook-Millstone Watershed property off Titusville Road to check out the pond trail. The pond itself held four Mute Swans, several Canada Geese and a few Mallards. The area around the pond looked promising for sparrows but held only a few White-throated Sparrows - their numbers have been low this winter and it would not surprise me if they have stayed further north courtesy of good food crops and mild temperatures this November. Once the snow comes perhaps they will drift south.

Barnegat, Tuckerton, Brig/Forsythe

I did a fairly conventional coastal route on Saturday morning - starting at Barnegat for something of a quick "coverage" visit, I found the state park closed (opens 9am these days?) and a lot of fishermen on the jetty and elsewhere. There was also a lot of boat traffic heading out of the inlet, so there were no birds in the inlet itself. However there were a lot of birds in the bay - recent warm weather undoubtedly contributed to the presence of Forster's Terns, although they are quite hardy. Also present was a substantially less hardy first winter Common Tern. Bonoparte's Gulls were particularly numerous and it seems that this species (along with sea ducks, Gannets and Red-throated Loons) have been on the move in large numbers this past week. There were actually relatively few loons in the bay. I took a look out toward the ocean from the end of the concrete walk and could see several groups of Northern Gannets headed south - surely meaning that thousands were on the move.

I left Barnegat pretty quickly - something that proved to be a mistake since both Western Tanager and Ash-throated Flycatcher were reported from the state park later that morning.

Great Bay WMA at Tuckerton was pretty quiet and I saw none of the Sharp-tailed Sparrows that I had gone there to look for. Boat-tailed Grackles and Black-bellied Plovers were the only birds of note.

Finally, then, to Brigantine division of Forsythe NWR where Tundra Swans have moved in, along with a much larger flock of Snow Geese than on my last visit here. Yellow-rumped Warblers and a heard-only Eastern Phoebe were enjoying the warm temperatures, but as usual with Brig in late fall it was mainly about ducks: Northern Pintail, Mallard, American Black Duck and Green-winged Teal were plentiful and supplemented by Ruddy Duck, Bufflehead, Scaup sp., Hooded Merganser. Raptor sp. were mostly Northern Harriers with one or two Peregrines and a single immature Bald Eagle.

Snowy Owl, Merrill Creek

There's a well-known Snowy Owl at Merrill Creek Reservoir that I went to see on Thanksgiving morning, although I had actually seen it the week before. Although I usually have reservations about "advertising" owl locations this bird has been present for a while and the location is widely disseminated.

Merrill Creek have closed the section of trail that runs down the east side of the southern dam, and the ranger I talked to indicated that this was to protect the owl roost location since people were getting too close. And in fact the Snowy was roosting next to a small rock ledge right adjacent to the closed path. It wouldn't surprise me if the bird had regularly been spooked of it's roost by the overzealous. The ranger indicated that the owl has probably been eating the gulls that roost there in considerable numbers late in the day.

Birding at Merrill Creek was otherwise quite slow - a single Bald Eagle, Horned Grebe, Belted Kingfisher and little in the way of land birds apart from Eastern Bluebird (heard) and American Goldfinch at the boat ramp parking lot.

Great Horned Owl in suburbia

Periodically I entertain a fantasy of finding a Screech-Owl or a wintering Long-eared Owl amongst my spruces, but it was a pretty big surprise to realize that I was hearing a Great Horned Owl hooting in my own neighborhood.

It was close enough and with enough low frequency that I could get a faint hint of it at 3am even with the windows closed, and I wandered outside to see if I was simply hallucinating or if it was by some miracle in my yard. Neither - it was a single bird, presumably wandering looking for a mate, and it was about two rows of houses over. There was no reply, and I've never thought of my neighborhood as having a quite dense-enough habitat to attract a Great Horned.

Still, it makes my yard 'B' list for things heard/seen from the property.

"Rufous" Hummingbird, Lenoir Preserve

Vagrant western hummingbirds are what spurred my whole web site development in the first place. My first home page was a precursor to what is now located at philjeffrey.net/Hummingbirds.html and was prompted by the first Rufous Hummingbird I saw at Lenoir Preserve in Yonkers in November 2001. That was the same year as the Fort Tryon Calliopes.

So it was natural that I wanted to go check out the latest hummingbird vagrant at Lenoir, even if Yonkers is a lot further away from home than it used to be. It took me a little while to find the Selasphorus sp. hummingbird, but it was probably sleeping or torpid before the sun started hitting the trees and butterfly garden. Once things started to warm up I saw it spending most of its time insect catching in the trees and the garden as the sun started to hit it. It spent some time in the Salvia Pineapple Sage at the edge of the garden, and a small amount of time at one of the feeders. From plumage the bird was an immature female, but this hummingbird was fairly shy and I didn't get anything remotely like a tail spread shot. The consensus is that it is a Rufous Hummingird (now apparently confirmed), although the staffer at the visitor center indicated that there was a suspicion that it was an Allen's and would be caught to determine which.

I'm pretty much invariably against capturing vagrant hummingbirds out of pseudo-scientific curiosity because it's not part of any systematic research plan and these birds are under enough stress attempting to survive in alien habitats in deteriorating weather. The cost to the bird is significant, and it tells us almost nothing.

There's a proposal to close Lenoir Preserve visitor center being considered by Westchester County - you could email the County Executive (Robert Astorino, ce@westchestergov.com) to express your opposition to this plan. The budget vote is apparently Dec 27th 2011, so sooner is better than later. (Updated to reflect the fact that it's apparently the staff that are getting fired rather than the preserve closed to all access).

Bryant Park on Nov 6th

I decided to pursue the Yellow-breasted Chat at Bryant Park in the city on Sunday morning, staying clear of Central Park because of the NYC marathon. The main body of Bryant Park is full of pop-up micro stores hoping to make it big for the holiday season and an ice-skating rink sponsored by Citibank, which makes it all the more remarkable that the park was loaded with White-throated Sparrows. Also there: one American Robin, one Ovenbird (my new late date for Ovenbird), a few Hermit Thrushes, Yellow-bellied Sapsucker. I finally found the not-especially-tame Yellow-breasted Chat out front of the library at the same location as the previous year's Prothonotary Warbler. But it did not pose for pictures like the Prothonotary did and was singularly obsessed with hunting down food. This has been an outstanding year for the normally rare Yellow-breasted Chat in NYC but it's also interesting that Bryant Park hosted another Chat in 2002 which put it on the map for birders.

Unfortunate footnote to this trip was finding three dead Red-winged Blackbirds - all males - on the sidewalk just west of Bryant Park. Probably window strikes.

Sandy Hook (fail), Pole Farm on Nov 5th

In search of a Harris's Sparrow at Sandy Hook on Saturday I did encounter a whole lot of birders, but only commoner sparrows (White-throated, Song, Dark-eyed Junco), an Indigo Bunting, Yellow-rumped Warblers, Hermit Thrushes, fly-over Horned Larks and a Northern Harrier. No Harris's seen by anyone all day and since there wasn't even a good hawk flight I departed after a few hours. The bay and Atlantic shore only held minimal numbers of diving ducks.

A sunset visit to Pole Farm (Lawrenceville) to check the prospect for owls revealed no Northern Harriers and no pre-dark Short-eared Owls which suggests that this location will be a bust in the 2011/2012 winter. A consolation prize was a Merlin perched at the parking lot, which somewhat agitated a local American Kestrel - at one point both were perched in the same tree looking at each other. I also heard a distant Belted Kingfisher.

Land bird migration, Nov 4th

Although more at work than birding, signs of passerine migration were obvious: flocks of American Robins at mid-altitude over Ewing after sunrise, more on the ground in Princeton, then more flocks headed south west over Princeton U. campus around 10:45, along with an icterid flock and a Cedar Waxwing flock. Two Golden-crowned Kinglets were feeding in the trees outside the lab.

Central Park Oct 23rd

Central Park was notable for a good push of late fall migrants: lots of Hermit Thrushes, Song Sparrows, Yellow-rumped Warblers with quite a few Ruby-crowned Kinglets and Gray Catbirds. The diversity was low - something that had something to do with me staying put in the Maintenance Field for a couple of hours watching the flocks of sparrows working their way through. The warbler count was fleshed out by a lone Magnolia (my new late date, and pushing it's luck) and one Palm Warbler. The usual late fall additions of Purple Finch and American Goldfinch were absent, presumably because of good crops in the north this fall and the consequent lack of an invasion year.

Brigantine and Tuckerton Oct 16th

(Catching up with old neglected sightings)

I went to Tuckerton and Brigantine NWR on a windy but sunny Sunday morning to pursue reported Ammodramus sparrows, with little success, but ended up with my first Cape May Warbler for NJ (other omissions that you might consider surprising include Bay-breasted, Wilson's and Tennessee).

At Tuckerton the brisk wind had the passerines seeking cover, so it was a bad day for sparrows and I was a little early for a high tide to push the sparrows out of the saltmarsh. Instead I contented myself with multiple flyover shorebird flocks: Black-bellied Plover, Red Knot, Sanderling, Dunlin, Semipalmated/Western Sandpipers (uncertain which). A sheltered spot along Great Bay Blvd yielded one or perhaps two Cape May Warblers but it was mainly Yellow-rumped Warblers in that flock. Northern Flicker along that road, somewhat out of habitat also provided the impression of migration. There was also a brief glimpse of a fat hummingbird. I'm calling it Ruby-throated by default, not least of all because fall migrant hummingbirds are often loaded with fat prior to migration and look bigger - but I really can't rule out Selasphorus hummingbird (Rufous/Allen's) for which the date and the location would also be possible.

Further down the road at Brigantine NWR there were some shorebird flocks, largely the same composition but without the Knot, and quite a few waterfowl. For some strange reason I had left the scope at home so I lacked things like Wigeon and Gadwall but the other usual suspects: Am. Black Duck, Mallard, Shoveler, Green-winged Teal, abundant Northern Pintail. There was also a small flock of Snow Geese - far short of the population that usually winters here so apparently a vanguard. Unlike Brant Geese, which tend to do the whole migration in one flight, non-stop, Snow Geese stage at multiple points as they "drift" south.

There was a lot of raptor activity at Brig, including at least two Bald Eagles, a few Northern Harriers and one or two Peregrines which were enthusiastically harassing anything small in sight (so I assume they were hungry). There were also noteworthy flocks of two other species: Forster's Terns present in quite high numbers, and also good numbers of Double-crested Cormorant, apparently mostly immatures.

Central Park Oct 5th

Trying to leverage a "spare" morning w/o meetings and some pro-migration weather I went into Central Park on Weds morning and found moderate but not spectacular migration. Warbler numbers were not epic, but there was a decent amount of sparrow movement including three Lincoln's Sparrows. Some time spent at the Maintenance Field didn't yield the Chat, but I did have a fly-over Common Nighthawk which is somewhat of a novelty. The Eastern Wood-Pewee I saw in Strawberry Fields is getting late-ish but my late dates are 10/18/03, 10/16/05 - however for most years this would be my late date for Pewee.

There was a small flock of Golden-crowned Kinglets in Strawberry Fields, Yellow-bellied Sapsucker and Hermit Thrush elsewhere - more in tune with late fall migration. I also saw two flocks of migrating Canada Geese that headed over the city to NJ, and three migrating Turkey Vultures.

Central Park Oct 2nd

A repeat performance on Sunday morning showed signs of much slow migration. In particular the surface winds had shifted toward the east, and I only had 3 warbler sp. in Strawberry Fields when I started there an hour later than Saturday. The flight of Blue Jays was replaced by a small one of Northern Flickers and the hawk flight was minimal in the contrary winds.

The Maintenance Field was again the best place, with the continuing Chat and other warblers bringing it up to a total of 12 sp although in lower numbers than Saturday and there was also a visit by a Yellow-billed Cuckoo - I've actually seen more Black-billed than Yellow-billed this year.

Central Park Oct 1st

With favorable conditions for migration I made it to Central Park via the absurdly early 0612 train out of Princeton Jct and was rewarded by a pretty decent movement of warblers in Strawberry Fields where I racked up 9 species in the space of half an hour. There was an obvious good movement of Blue Jays with me seeing over a hundred in various flocks during the day.

Most other areas were quiet, but the Maintenance Field held a Yellow-breasted Chat that was mostly skulking, and also was a good observation point for a decent hawk migration - mostly Sharp-shinned Hawk (10+) but also several Cooper's Hawk, American Kestrel, Osprey, Peregrine and one likely Merlin. Gadwall and Solitary Sandpiper were on Turtle Pond.

The Chat was the first one of the year for me (and likely the last).

A lack of Kinglets and Sapsuckers made me think that there was a decent amount of fall migration still to come, even if it was October 1st.

Central Park 9/25 (Cuckoos, Tennessee)

Quite a slow start in Strawberry Fields, where I learnt that early in the morning a Mississippi Kite had been seen overhead by Peter Post. However migrant activity was extremely patchy in the initial overcast of the day. Wandering into the Ramble I got a #cpkbirds tweet about a Yellow-billed Cuckoo at the Upper Lobe and went over to check it out. The lone willow tree was quite active with multiple Rose-breasted Grosbeaks and Gray Catbirds, a few Swainson's Thrushes, Pewee and Phoebe. There were also one or two warblers including the lone Northern Waterthrush for the day. Being there for a while I saw a cuckoo fly down the Upper Lobe and assumed it was the Yellow-billed. However some time later a Black-billed Cuckoo flew into the willow, and gave quite a few people good looks especially when it was out on a sunny rock on the other side of the lobe.

From the Upper Lobe I went to the Maintenance Field which also was moderately active. After a few minutes I found another Black-billed Cuckoo - this must have been quite a good Cuckoo day since Yellow-billed were also reported from these same areas earlier. Here I also picked up migrating raptors: Osprey and Sharp-shinned Hawk, although that activity was slow. A few Monarch Butterflies were migrating. While here I "heard" of a third hand report of Tennessee and Connecticut Warblers in some vaguely defined area "near Tupelo". I elected to stay and do a little hawk watching since it had been a long while since I had seen a kettle of Broad-winged. At one point there were two Eastern Phoebes and at least two Eastern Wood-Pewee's flycatching here.

This was a bit of a mistake - there was a Connecticut near Tupelo giving excellent looks, and by the time I got there it had gone. Although I did see: Tennessee and Nashville Warblers and several other warblers (Ovenbird, C. Yellowthroat, Black-throated Blue, Magnolia, Restart). They all particularly liked the insect-laden asters as the sun warmed them up.

Shame about the Connecticut since it's rare to get good views. However it's also been a long while since I had eye level looks at Tennessee in fall in the park, so that's the consolation prize.

(On the way home I stopped at the Allentown NJ sod farms and finally picked up American Golden Plover for the year).

Ewing/Backyard 9/24

Migrants:
Northern Parula (2+)
Magnolia Warbler (2)
American Redstart
BLACKBURNIAN WARBLER
Chipping Sparrow (multiple)

and the local boys:
Carolina Wren
Carolina Chickadee
Tufted Titmouse
Downy Woodpecker

Considering that I hardly ever see Blackburnian in fall, this was a good find and a new yard bird.
Once again the mixed species flock is a reliable locator of migrants. This is also an early date for fall migrant Chipping Sparrows, although none of them stayed in my yard.

Central Park 9/17

After what was reported to be a fairly good migration on Friday, Saturday was quite slow. A few warblers in a few pockets, the most interesting of which was a Pine Warbler. Raptors didn't put in much of a show either: 3 Ospreys and an Accipter sp as well as three local Red-tailed Hawks.

Osprey
Northern Flicker
Eastern Wood-Pewee
Blue-headed Vireo
Red-eyed Vireo
Veery
Swainson's Thrush
Northern Parula
Magnolia Warbler
Black-throated Blue Warbler

American Redstart
Common Yellowthroat
Scarlet Tanager

Although what was by far the most interesting bird was actually an unidentified one. A small active vireo in the Maintenance Field rang internal alarm bells on the grounds of "potential Philadelphia". This has a troubling overlap with immature Warbling in fall, and this individual was too far away and not giving easy looks. What was evident was that it was almost warbler-esque in activity and looked a little small. However the definitive ID points for Philadelphia were absent - it was not yellow from throat to breast and it didn't have an evident dark mark between eye and bill. I decided "Warbling" at the time based also on a single buzz call, but most vireos sound the same and in retrospect I'd be tempted to call it a Philadelphia Vireo but frustrated at not being sure about it. Quite a few other Philadelphias from other locations make me especially curious about this bird.

Mixed species flock in Ewing 9/17

And by Ewing I mean in my yard in NJ. I was tinkering with the aging Honda's splash guard and heard a mixed flock moving through.

The local boys were:
Downy Woodpecker
White-breasted Nuthatch
Carolina Chickadee

However they were accompanied by a rather nice selection of migrants:
Northern Flicker (multiple)
Gray Catbird
Red-eyed Vireo
American Redstart
Northern Parula (multiple)
Blackpoll Warbler
Black-throated Green Warbler
Chestnut-sided Warbler
Common Yellowthroat

and the finale was a high altitude Osprey coasting over the yard headed for the Delaware River. The Osprey and three of the warblers were yard birds. The species list also compares pretty well to my Central Park sightings list from earlier in the day. I also heard a Song Sparrow sound off, which may or may not be a migrant - most summer breeders leave my yard before fall migration, which is why Gray Catbird is included on the migrant list.

NYC Checklist Updates

The checklist that I've been maintaining at
http://www.philjeffrey.net/NYC_unofficial_list.html
has been updated to reflect the amazing fallout as a result of Hurricane Irene. What was added was:

Cory's Shearwater (Bronx)
Great Shearwater (East River, Brooklyn)
Audubon's Shearwater (Bronx)
Band-rumped Storm-Petrel (Bronx)
White-tailed Tropicbird (Manhattan)
Sooty Tern (several)
Bridled Tern (Staten Island, Brooklyn)

although of course this list could conceivably get modified by virtue of NYSARC rulings.

Other noteworthies such as Leach's Storm-Petrel were already on the list, although remarkable finds in themselves.

Given the conditions I personally didn't see any of these birds - while they were being recorded off Brooklyn and Manhattan (and a similar lot off Cape May) the conditions were simply too hazardous to consider driving that far with high winds and potential flooding. Instead I picked up inland Laughing Gulls (three juveniles over Mercer County Park). The pelagics cleared out fast - I got down to Cape May the following morning but there was pretty much nothing out on the ocean, although Bill Boyle did point out a fly-by Sandwich Tern along the beach which turned out to be a new NJ bird for me.

Central Park 9/10 and 9/11

A fairly slow migration day on 9/10 saw me in Central Park for my first fall birding trip to NYC. The number of warblers were fairly low for a northerly wind and I found:

Osprey
Northern Flicker
Eastern Wood-Pewee

Swainson's Thrush
Wood Thrush

Black-and-white Warbler
American Redstart

Noteworthy were the Yellow-bellied Flycatcher (first of year for me) and EIGHT Osprey making their way south.

On 9/11 I returned to Central Park without expectation of finding much. However I was living in Manhattan on 9/11/01 and birding Central Park that morning - an experience best related elsewhere, if at all - and this visit was more about symbolism than anything else. As expected it was much quieter even than Saturday. I added Northern Parula (3) and Yellow Warbler to the previous day's warbler totals but left the park fairly early for brunch rather than keep staring at trees full of American Robins and not much else. Of note were two White-throated Sparrows, one of which was singing. There was no hawk movement to speak of on Sunday.

Parasitic Jaeger and Brown Booby (in NJ!)


This has been quite the year for life birds, including exotic ones (Rufous-backed Thrush, Black-vented Oriole, Laysan Albatross, Short-tailed Albatross, Gray-hooded Gull), so when a Brown Booby turned up in Cape May I doubted my luck would run so far as to have it stick around.

Instead I headed for Bombay Hook NWR (Smyrna, DE) in the morning to look for shorebirds, and apart from the belated year bird American Avocet and some Blue Grosbeaks wasn't all that blown away by things. Checking email I saw that the Booby was still being seen, so I made a 2.5 hour "sprint" across the southern tier of NJ to Cape May, where I saw the Brown Booby perched on a distant marker just before 1pm. Since there was a 1:30 sailing of "The Osprey" I called them up while looking at the Booby through the scope and hopped on the boat to take a closer look. And a closer look it was, with the Booby seen from perhaps 50 feet away.



What's even more remarkable is that it was an adult - usually only juveniles go way out of range. Notably other Brown Boobies had been seen very recently in Massachusetts and Maine - a mini invasion of a Caribbean bird that only breeds in the USA on the Dry Tortugas.

Also seen from the tour were several Whimbrel, a Marbled Godwit and a few Black Terns amongst commoner species. After the tour ended I braved traffic to go to the "Concrete Ship" at Cape May Point. I hadn't even put the 'scope down when a Parasitic Jaeger flew by (a dark-ish juvenile). I had been extra-conservative about Parasitics despite seeing two in Avalon over a decade ago, and "seeing" one or two on pelagics, but this was getting silly so I decided to add it to my life list after all. Also at the Concrete Ship were lots of terns (Common, Forster's, more Blacks, Least, Royal), a lot of Laughing Gulls, with Sanderling and Semipalmated Sandpiper on the beach. I couldn't pull in any Storm-Petrels out over the ocean but it was windy and murky by this point. I headed home through a line of strong storms flash-flooding the roads in places.

Gray-headed/hooded Gull

(Gray-hooded in AOU area - they just have to be different; Gray-headed everywhere else).

A bird originally identified as a Black-headed Gull had its ID corrected on Thursday from something semi-rare to something exceptional. Two birders had spotted a Gray-hooded Gull on the Coney Island beach on 7/24, and thank God they took a photo of it.

As you might expect with a rare bird that's been seen precisely once in the USA over a decade ago, some civilized panic occurred. Not seen Friday morning but seen Friday afternoon, seen off and on during Saturday, I finally decided to go look for it late morning on Sunday. Since I started out first at Negri-Nepote (Blue Grosbeak, Grasshopper Sparrow etc) I accelerated arrival time to mid morning since it had already been seen.

I actually saw it while walking toward the group of birders on the boardwalk because it has a very distinctive flight pattern with large white mirrors above the black primary tips. On the ground it was a little less obvious with the gray hood and black collar less pronounced than some photos of birds in fresh alternate. Overall plumage condition is a little worn but consistent with an adult in late alternate with year-old primaries and retrices. It's pretty tame but no tamer than the Laughing Gulls it's taking its cues from. It's a little smaller than a Laughing Gull but not by much.

I'm still not sure this qualifies as a countable species - while I don't see any captive origin issues for the bird and there's no particular reason to believe ship-assistance it's still a quite remarkable record well out-of-range.

A picture from August 2nd, when I made a second trip to see this bird:

Negri-Nepote

On a marginally more palatable day I went walking in the early morning at Negri-Nepote Grasslands in Franklin Twp NJ. This place was full of passerines with a good number of juveniles. I saw more Grasshopper Sparrow juveniles than anything else, which is really good news for this very uncommon species in NJ. One or two adult males were still singing, and I saw one adult carrying food.

One species conspicuously absent were Dickcissel - they haven't been seen here in a few weeks.

Other sparrows at Negri-Nepote included Chipping, Field (+juv), Song (+juv), a singing male Blue Grosbeak (not seen) and there were also American Goldfinches, Indigo Buntings and fly-over House Finch. I also saw multiple House Wrens (one using a Tree Swallow box), a Prairie Warbler, a few Orchard Orioles, Cliff/Barn/Tree Swallow, three eclipse plumage Wood Ducks on the pond that is drying up. Also of interest there were a flock of 10+ Bobolinks - although this is a grassland they don't breed here for reasons that must be to do with the habitat mix, but Bobolinks breed early and migrate early. These birds were southbound migrants including molting adult males.

Brig 7/23

Short birding trip (truncated by heat and Tour de France coverage). I went zero for everything on the rarity front at Brig despite checking Glossy Ibis facial skin color (for White-faced) and there being feeding frenzies at very low tide at a few of the sluices (Forster's Tern, Laughing Gull, Double-crested Cormorant).

Shorebird numbers were up, mainly Semipalmated Sandpiper (abundant, thousands) and Short-billed Dowitcher. My best birds were Whimbrel and Pectoral Sandpiper, both year birds, before heading for cover and air-conditioning.

Brigantine NWR

A warm Sunday visit to Brigantine, although I actually started off at Great Bay Blvd in Tuckerton, just to the north. Along Great Bay there were multiple singing Seaside Sparrows but I was unable to come up with Saltmarsh (Sharp-tailed) Sparrow. Also there: Boat-tailed Grackle, Laughing Gull, distant Forster's Terns, inevitable Red-winged Blackbirds, sizable flocks of Tree Swallow on the wires, and I heard a couple of Clapper Rails. A couple of Least-ish Sandpipers flew over the road, a reminder that fall shorebird migration had already started.

Then to Brigantine where the Purple Martin colony was in full swing. The tide appeared to be high but on the way down. Activity at Brig wasn't all that impressive, especially on the shorebird front: Short-billed Dowitcher, Lesser Yellowlegs, Greater Yellowlegs, Spotted Sandpiper, Least Sandpiper, Stilt Sandpiper. OK, the Stilt was certainly a decent find, and was an adult in fading alternate plumage. At this time of year pretty much all of the birds are adult in faded alternate plumage since it's too early for juveniles to be in a condition to migrate south. Terns included the inevitable large numbers of Forster's which nest out in the saltmarsh and are just starting to show signs of molt in a few cases (into basic plumage). At the south-eastern sluice there was a single Common Tern (semi-reliable here) and a few Gull-billed Terns were dotted around the place. Canada Geese appeared to be at an all-time low for a summer in which I'd normally expect to find lots of juveniles along the drive. There were several Osprey nests with young but the really photographically convenient nest from last year was inactive - I thought that one was a little too close to the wildlife drive and is inactive in most years. I didn't find Saltmarsh at Brig either, but Seaside Sparrow, Marsh Wren, Common Yellowthroat, Song Sparrow, Indigo Bunting and Blue Grosbeak were present. The male Blue Grosbeak was singing and was my first one for the year - not at all common this far north. A fairly typical results for Brigantine but nothing at all compelling.

(Update: 7/17 there were pretty much the same species but also Least Tern family group with juveniles).

Hooded Crow, Staten Island

This bird is an Old World species of crow, the Hooded Crow, at Crooke's Point of Great Kills Park (part of the Gateway National Recreation Area, just as Jamaica Bay WR is). Back when I still lived in Britain it was a subspecies of the Carrion Crow (Corvus corone) but subsequently was elevated to full species status as C. cornix. Hooded Crow is somewhat of a predator, and the local several pairs of Northern Mockingbirds instinctively know this - they're mobbing the crow quite hard whenever it pops into the parking lot, and often on the beach too. So although the above photo looks like they're companions, nothing could be further from the truth.

This is a pretty significant vagrant, or at least would be if they had much of a migratory habit - Hooded Crows show shorter range migration in winter as a reaction to hard weather (rather like Blue Jays) but like all the crows that I'm familiar with are mostly sedentary. Given the location it's rather tempting to think this was a ship-assisted bird. It could also be an escapee, but there's no obvious feather wear from a cage and the bird is fairly wary. Strongly suggestive of wild origin but I doubt it flew trans-Atlantic under its own power.

Also at Great Kills: Brown-headed Cowbirds incl juveniles (why can't the Mockingbirds harass these ?); Yellow Warbler; Willow Flycatcher; Gray Catbird; Common Tern; Osprey; the usual suspect on the Gull front.

Update: the Hooded Crow moved off Staten Island not long after I saw it, but was found again hanging out on Long Beach Island in New Jersey (this is south of Barnegat Light, so it's traveled a fair distance). As of August 5th it's still present.

Out of area: WA/OR trip

On probably the last birding trip of the year - since I do mainly late winter and early summer trips - I went to the last chunk of the lower 48 that I hadn't really birded, the Pacific NW. I wound up with 19 life birds which is rather remarkable given that I started out with 622 USA species and it's hard to envision adding 19 in one trip. 9 of these were added in one day on a Westport Pelagic trip on 6/25: Sooty Shearwater, Pink-footed Shearwater, Fork-tailed Storm-Petrel, Leach's Storm-Petrel, Black-footed Albatross, Laysan Albatross, Short-tailed Albatross, South Polar Skua and Cassin's Auklet. The Laysan's is fairly rare, but the Short-tailed Albatross is a real rarity with much excitement on the boat - there are only ~2,400 in the world. This one was an immature. Laysan is also unusual but it's possible that the tsunami kicked many off their breeding grounds this year. Previously I'd seen one Albatross species: Royal Albatross in NZ. I added 3 new ones on this trip.

Other lifers: Rhinoceros Auklet, Marbled Murrelet, Common Murre, Tufted Puffin, Pacific Wren, Red-breasted Sapsucker, Northwestern Crow, Vaux's Swift, Cassin's Vireo, Tricolored Blackbird.

Pretty much impossible to see more than a few life birds in one trip in the Lower 48 going forward.

Arizona in flames

Way out of area, but anyone who has birded the sky islands of south-east Arizona can understand the cumulative horror of the extensive wildfires that are active right now.

The Chiricahua's (Portal, South Cave Creek, Paradise) are extensively burned, with a firestorm nuking Rustler Park, but S. Cave Creek partially saved by preventive burns. (Inciweb for Horseshoe Two, Coronado NF). The boundaries of this fire extend over the entire AZ Chiricahua footprint.

The nigh-on half-million acre Wallow fire at the eastern edge of AZ (away from the sky islands but still in valuable montane habitat).

The evolving Monument fire in the Huachucas (inciweb link now active) which appears to have consumed chunks of Ash Canyon and rumor has it burning Mary Jo Ballator's birding B&B. There was a brief fire in Ramsey Cyn recently. Evacuation seems possible for Miller Cyn now. Lack of containment on that fire would see decimation of Miller, Carr and Ramsey Cyns.

The Murphy fire west of I-19 and nw of Nogales that probably burned out Sycamore Cyn and covered the area around Pena Blanca Lake.

So far Madera Cyn and Mt Lemmon don't have fires on them or this might constitute a total loss of habitat. Of course fires are part of the natural process and some fire suppression policies in national forests might have contributed to the severity of this - but the drought is the biggest issue and perhaps these fires won't be totally over until the monsoon season in July, assuming it arrives.

The fires mentioned above cover large areas that I visited in the AZ segment of my AZ-NM-CO birding trip in 2006 (Sycamore, Ramsey, Miller, Carr, Ash, S. Cave Creek Canyons, Rustler Park in three different mountain ranges)

Negri-Nepote Dickcissel

Trying to pack in a few breeding season sites in good weather before I wander off to the Pacific NW I went to Six Mile Run (Grasshopper Sparrow etc) and Negri-Nepote Grasslands. I've been to Negri-Nepote before but not very often - it's just far enough away to represent a higher effort barrier. However this Franklin Twp-managed site is better than Griggstown and probably should become my spring-summer alternative to that.

For example: I heard (and probably saw) a Grasshopper Sparrow within the first 200 yards from the parking lot at Negri-Nepote. I wasn't there for very long since this was a short visit sandwiched between Six Mile Run and work. Predictable birds were: Indigo Bunting, House Wren, Field Sparrow, Common Yellowthroat. On the pond was a male Mallard, Killdeer, Great Egret and a swarm of feeding swallows (Tree, Barn). The bird I mainly came to see was a singing male Dickcissel, given a relatively monotonous and uninspired song even compared to other Dickcissels, but it did make it pretty easy to find.

Dickcissel's breeding range once covered the Atlantic coast but breeding in this area has become a rare to very rare event. They breed here and there in Delaware, but breeding in NJ is extremely irregular. Normally I see this species as a misdirected fall migrant (Jones Beach) or more rarely as a spring wanderer (Central Park) but this is the first Dickcissel I've seen in NJ. Unlike the movement of Cassin's Sparrow's east in response to the major drought of the interior west, there's no obvious climatic reason for Dickcissel turning up in NJ. I saw some in very late May in coastal TX at Anahuac NWR, in March in FL, and for me this is a banner year for them since previously I've seen them very infrequently.

Grasslands, 6/12

Sunday wasn't any better weather-wise than Saturday, and in fact it was lightly drizzling by the time I reached Six Mile Run State Park (Franklin Twp, NJ). I found the usual suspects fairly straightforwardly: the usual Willow Flycatcher tussle near the parking lot (could it actually be the same two males each year), American Goldfinch feeding in the thistle, Tree Swallow and Barn Swallow, Field Sparrow, Grasshopper Sparrow out in the field. One Grasshopper Sparrow was singing consistently and the other one (also probably male) was just giving contact calls. One singing male Indigo Bunting, a distant Prairie Warbler, Eastern Bluebirds, and an adult Cooper's Hawk hunting the area. The Red-winged Blackbirds must have just fledged or be close to it - several males ended up hovering in an agitated way over my head although they didn't dive-bomb me.

No orioles and no Blue Grosbeak, but Willow Flycatcher and Grasshopper Sparrow were new birds for the year.

A few miles to the south I visited Griggstown. I didn't hear any Grasshopper Sparrows, nor any Indigo Buntings, but I did add both Baltimore and Orchard Orioles for the day. Red-winged Blackbird numbers seemed low and this site definitely appears not to have bounced back from mismanagement in recent years. We shall see if it pulls in the sparrows this fall.

Baldpate Mtn, 6/11

An early morning check of the radar showed a patch of thunderstorms headed toward Mercer county so I ran errands while waiting for the storms to pass by. Afterwards I drove up to the top of Baldpate and found almost exactly the same species as a previous visit. Notably no Kentuckys singing at any point, although it being later in the morning and later in the year may play a role.

I also explored the trails off the north side of Baldpate via the parking lot at the powerline cut. This had lots of habitat that seemed Hooded/Kentucky-friendly yet I only came up with one singing Hooded on the mile-long loop trip.

Upsides were House Wren nesting in the trail map structure, Great Crested Flycatcher, singing Blue-winged Warbler (not seen).

Louisiana May-June

Away from the NYC area I took advantage of a conference trip to New Orleans in late May into June to do a little birding for one of my nemesis birds: Bachman's Sparrow. Via my own research and a lot of helpful advice from TX birders they weren't all that hard to find at Boykin Springs and another site, both near Jasper TX in the pine woods at the eastern edge of the state. As a bonus I saw two Red-cockaded Woodpeckers at the second site, these being my second and third RCWO respectively.

June is going to be the month for trips - I'm off on a pacific northwest trip in two weeks.

Central Park 5/24

On the day before setting off on my Louisiana conference trip I took a morning and birded Central Park for almost certainly the last time this spring migration. Spring migration started with a bang in late April where everything seemed early, then stalled with bad weather in the traditional peak window.

So here we are on May 22nd, and there's still a fair number of adult males singing in the trees: Northern Parula, Ovenbird, Common Yellowthroat, Blackpoll Warbler (inevitable), Canada Warbler, American Redstart, one or two Magnolia Warblers, Black-throated Blue Warbler. Adding to the warbler list was Northern Waterthrush and Yellow Warbler. But most species were heard singing, although it was a mix of males and females seen. Migration may have some legs yet, but I'll be away for close to two weeks and I anticipate things will be pretty slow by the time I get back out.

Best bird of the day was a Lincoln's Sparrow at Tanner's Spring.

Delaware Bay Shore, 5/22

It was heavy overcast and drizzle, with non-migration-inducing winds on Saturday night, so I gave up on any idea of going into Central Park and went in the opposite direction to the NJ Delaware Bay shore instead.

I got a slow start, the light rain not being much of an inducement, but it was merely overcast when I made it to Belleplain State Forest at 10am. Along the usual stretch of Sunset Road I hard a distant Prothonotary Warbler, a closer (but equally elusive) Louisiana Waterthrush, and a Yellow-throated Warbler in the pines there. All were heard-only as was a Worm-eating Warbler and a probable distant Kentucky. Birds I actually did see at Belleplain were Acadian Flycatcher, Great Crested Flycatcher and a Blue-gray Gnatcatcher on its nest.

Belleplain SF was not my main target, which was instead saltmarshes and coastal ponds. I went to Jake's Landing and on getting to the parking lot the first sparrow I put my eyes on was a Saltmarsh (Sharp-tailed) Sparrow - not something I see each trip there, although this was the site of my life bird. Shortly afterwards the first of several Seaside Sparrows and Marsh Wrens doing little song flights. The species were the usual selection (Willet, heard Clapper Rail, Snowy Egret, Glossy Ibis, Osprey, Forster's Tern) and since it was both breezy and overcast I left before too long - I did see one Northern Harrier which suggests they might be nesting there again.

My main interest for the day was migrating shorebirds at the impoundments along Matt's Landing Rd at Heislerville. I got there a little before noon with a projected high tide of something like 1:30pm and there already were a lot of shorebirds in the pool. Hundreds per minute were coming in as the tide rose. There was a multi-thousand swarm of Semipalmated Sandpipers (year bird) but I was lucky enough to find the female Curlew Sandpiper within the first 30 seconds. They prefer the mud and shoreline rather than wading, so despite being similar to Dunlins (but longer-legged) they don't spend much time with them. A little later on the brick red (but still a little mottled) male was found. The female showed remarkable site fidelity and kept feeding on the same 50 yard stretch of mud. Dunlin, Semipalmated Plover, Short-billed Dowitcher were also numerous. The Black-bellied Plovers were more elusive on the other side of the pond. The Black Skimmers were also present, along with Forster's Tern and a couple of Least Terns. I spent some time sorting through sandpipers and came up with three White-rumped Sandpipers - birds I don't see in alternate plumage all that often. Large numbers but not a lot of diversity - this habitat doesn't favor the Ruddy Turnstones (I saw 1) or Red Knots (zero) that hang out along the sandy beaches of the bay. The shorebird flocks were pretty nervous, and at one point a female Purple Martin was flushing them as it dove for insects over the mud.

Although there was a little sun down on the shore, back at home it was still solid overcast. A little migration had happened - as I was doing yard work I heard a singing male Blackpoll Warbler feeding amongst my spruce trees (which along with my big oak prove to be a favorite with migrant warblers).

Sterling Forest, May 21st

Back up to Sterling Forest on the first sunny day for a over a week, and as it transpired the only sunny day of the weekend. Getting there around 7:30am I checked Blue Lake, where there was little singing activity, so I spent the entire morning along the power line cut at Ironwood Road.

A relatively cool start after a week of rain, and there wasn't that much active singing. In particular I heard no singing Golden-winged until I turned around on the trail, which is where I saw my first male. By that time I'd already seen two singing Blue-winged and photographed a female that was paired with the first "Blue-winged".

I say "Blue-winged" because it was this bird - almost certainly the one that was singing in the same tree as the Golden-winged 10 days perviously - that had pretty obvious Golden-winged genes in it. From underneath it's an unremarkable Blue-winged, but when I saw it from the side the upper wingbar had yellow in it, and the lower wing bar was both broad and solidly yellow. The face was perfect Blue-winged, so it wasn't an obvious "Lawrence's" Warbler. Some sort of back-cross that was 3/4 Blue-winged and 1/4 Golden-winged. Based on tail feather shape (and wear?) it was a first spring bird. The only good thing about all of this is that it was at least paired with a Blue-winged female, not a Golden-winged.

I had three singing Golden-winged on the day, plus a good mix of other warblers: Cerulean (singing male, also seen), Yellow Warbler, American Redstart, Black-and-white Warbler, Magnolia Warbler, Chestnut-sided Warbler, Common Yellowthroat, Ovenbird (heard), Hooded Warbler (heard). That's down from my previous trip here, but a pretty good total given that there was little migration ongoing with another in a series of winds out of the east.

Other passerines: Indigo Bunting, Eastern Towhee, Field Sparrow, Scarlet Tanager, Baltimore Oriole, Yellow-billed Cuckoo (heard), Eastern Wood-Peewee and Great Crested Flycatcher. I also had an Empidonax-sp that looked a lot like a Least Flycatcher but I wasn't totally sure of it based on incomplete looks (but not Acadian or Yellow-bellied). Not a bad day and I stayed a little later there due to the slow start.

Of note were a young Snapping Turtle crawling up the hill, and a large (5+ ft!) Black Rat Snake sprawled across the trail and really quite sluggish in the lower temperatures of the morning.

Migration trickles on, between downpours

Even though the deluge is scheduled to continue for the first half of the week, it's nevertheless obvious that some birds are still moving in undesirable conditions.

Monday (17th): large 70++ flock of Cedar Waxwings on campus in Princeton; smaller flock of Cedar Waxwings at the yard in Ewing; Northern Parula singing late in the day at Ewing - a new yard bird.

Tuesday (18th): faint Blackpoll-sounding call from the trees in the yard, and an odd-sounding warble that transpired to be a Magnolia Warbler singing an underperforming song while resting in my spruce trees (probably still quite dry). Magnolia Warbler was also a new yard bird.

I am nervous what this cold-wet stretch of weather will do to tired migrants and early breeders, but at least some are finding food and shelter. It should start drying out and warming up on Thursday.

Baldpate Mountain

On the first morning of a week's rainy spell I assuaged some restlessness by hiking up Baldpate Mountain through some good eastern hardwood forest habitat after the latest line of storms had come through, although there was still light drizzle and quite a lot of water dripping from the trees. I started at the parking lot off Fiddler's Creek Road and decided to walk uphill on the road rather than slip on wet rocks along the trail.

Yellow Warbler, Eastern Towhee and Eastern Wood-Pewee were around the parking lot. On the walk up Wood Thrush, Ovenbird sounded off. Much of the birding today was by ear since the viewing conditions were pretty bad. I heard a distant Veery in the forest. But overall it was quiet, and it being cool and wet you really can't blame the birds. Towards the top of the road as the forest started to thin I added more Wood-Pewees, then Indigo Bunting, Field Sparrow, Chipping Sparrow and Yellow-throated Vireo. Up at the grassy meadow behind the house complex (the alleged visitor center that is never open) there were more Field Sparrows, Indigo Buntings, Common Yellowthroats and a couple of unenthused Blue-winged Warblers.

Hiking an upper section of the Summit Trail before it drops off steeply downhill I could hear Worm-eating Warbler, Blackpoll Warbler (migrant), more Ovenbirds but no Hooded Warblers. Going back down the hill on the road again I added Rose-breasted Grosbeak (a singing mail), possibly another distant Worm-eating, and on getting back to the parking lot once more there was a Northern Parula. Parula's sometimes breed around here, but this one was just as likely to be a migrant.

Before I went home I decided to check on the entrance on the other side of Baldpate, at Pleasant Plains Road, however once I found the trail head at the powerline cut the drizzle had really cut down below tree-top level. This entrance is worth exploring more, particularly since the powerline cut might attract more warblers (like Blue-winged), although it's not really quite the right habitat for Golden-winged or Chestnut-sided.

Central Park 5/14

Overcast skies made for difficult birding in Central park on Saturday morning. Initially in Strawberry Fields the going was pretty slow as well, and continued that way through the Maintenance Field. En route the Upper Lobe was a little better with a female Ruby-throated Hummingbird and a few warblers, including a very vocal Northern Waterthrush.

On reaching the Evodia Field, however, things lit up a lot. Within five minutes I found a singing Tennessee Warbler, a Blackburnian Warbler, and two Cape May Warblers chasing each other. Tennessee Warbler had become a mini-nemesis bird since I had systematically missed them for several springs in the park, but this one was belting out its song near the source of the Gill and impossible to ignore (that is, if you know the song). Later on the Cape May male was singing at the Azalea Pond. It was also my first of the year, as was the Eastern Wood-Pewee that was flycatching in the lower canopy.

Elsewhere, on the Point etc, the birding returned to relatively slow. Catharus thrush numbers continue to be low, with a couple of Swainson's adding to the now-resident (non-Catharus) Wood Thrushes.

There was a burst of migration in early spring in late April and the first few days of May, but the standard peak window of May 5th-12th has been much slower with less conducive weather patterns. Saturday was the start of some quite wet weather with predominantly east-originated winds and rain every day that may last this whole week and are especially non-conducive to spring migration birding. If migration doesn't go right past us (to the west of us) it could make for a strong migration burst next time the weather is more migration-friendly.

Sterling Forest

May 11th is the earliest I have ever been to Sterling Forest - when I first went there I favored early June although more recently I've been more likely to go there at the end of May. So this was somewhat of an experiment. The novel experience was the presence of some migrants in what otherwise would be considered classic northern deciduous breeding habitat (Yellow-rumped Warbler, Nashville Warbler, Blackpoll Warbler, White-crowned Sparrow). The female Black-throated Blue was probably a migrant too. In the end I racked up quite a decent total of warblers, although some species were heard-only, and unquestionably my best for this site.

The main targets at Sterling Forest are Golden-winged Warbler and Cerulean Warbler. I heard two Ceruleans and saw/heard about six Golden-winged. All males. I didn't see any sign of females but perhaps since this is mid migration they are en route. Unfortunately I also saw four Blue-winged, a personal high total, which doesn't bode well for this little enclave of Golden-winged. In fact one Blue-winged was singing in the same tree as a Golden-winged without territorial exclusion, which illustrates how this sort of hybridization can so easily come about.

My usual initial spot for Golden-winged has been trashed by the power line company, which likes to destroy habitat of endangered species by chemical and mechanical means. Looks like that will take a few years to bounce back, assuming it ever does. I've also seen these jackasses prune trees in breeding season, including destroying an American Redstart nest in the process and right next to a Golden-winged nesting site. Of course the power line cut itself is providing niche habitat for Golden-winged, especially after habitat encroachment or succession of its more usual sites. Golden-winged is essentially extirpated in NJ, at least from any publicized spots - the last site that I knew of near Layton has gone too far in succession. Although Cerulean is relatively rare, Golden-winged is much rarer as a regional breeding species.

However at least the most prominent spot for Golden-winged at Ironwood Road is mostly intact. Here Golden-winged, Prairie, Chestnut-sided, Yellow and Common Yellowthroat were on territory. I felt that the numbers of Prairie and Chestnut-sided were on the low side, but this may reflect ongoing migration especially of the latter species.

Scarlet Tanager as new yard bird

While making tea I heard a familiar song - one which I often describe as "a Robin on speed" - and tracked it down after a little while to a Scarlet Tanager that was singing from the top of my big oak in the back yard. It was just singing, not singing-while-feeding as a lot of warblers do, and in fact there were two Scarlet Tanagers with the other one singing from a distance to the north. A little later I heard a nearby Northern Parula sounding off. Despite the cool start to the day and what appears to be a north wind, some local migration must have happened.

Very gratifyingly, not only is Scarlet Tanager a new yard bird, but I also got to watch it sing for a while.

Sunday 5/8

This was a slower day, both measured in terms of the numbers of warblers but also the extent to which they quieted down by late morning. I did find a Cape May Warbler at Strawberry Fields, singing, but missed the Blue Grosbeak (a lingerer, presumably) and Bay-breasted Warbler. Cape May has been moderately numerous again this spring. Birds like Blackpoll Warbler and Black-throated Green Warbler were notably absent today.

By late morning I decided to pack it in and get some brunch at one of my old UES haunts. I had driven into the city and had parked at 79th/Madison.

After brunch I decided to hit a couple of birding spots and my preferred nursery before getting home. First stop was DeKorte Park in the Meadowlands Lyndhurst. DeKorte has great potential as a spring shorebirding spot if only they would draw down the water a little and expose a little more mud, even in one small section. In the event I saw Lesser Yellowlegs, Least Sandpiper (one quite advanced, very rufous, with a prominent white eye ring), and one Spotted Sandpiper. Also present were Gadwall, American Black Duck, Mallard (with ducklings), Tree/Barn/Bank Swallows. Passerine migration was also in evidence, with the trees and pond edge containing Yellow-rumped Warblers, Yellow Warbler and Common Yellowthroat.

After a visit to Belle Mead C0-op for grass seed, I went down to nearby Griggstown Preserve (Franklin Twp, NJ) to check for Bobolinks. Someone had reported quite a few near the parking lot. I found one, a male that still had a rather subdued plumage - either in mid-molt or a young bird. As often happens here, the Bobolinks drop in but don't seem to stick for very long. Also there was Orchard Oriole, Tree Swallow, Warbling Vireo and many Red-winged Blackbirds.

Saturday 5/7 - good migration

A pretty good migration happened overnight Friday-Saturday although the numbers were not huge in Central Park. In Strawberry Fields the diversity was decent and I picked up Blackpoll Warbler for the year (a singing male, one of a few that day and not atypical for the end of the first week in May). On the way into the Ramble I heard/saw Blackburnian Warbler and Northern Waterthrush and then shortly thereafter I found my first Swainson's Thrush for the year. It's not been a good year for Catharus-type Thrushes and Saturday was no exception with only a couple of Veeries and a Wood Thrush to add to the total (and Wood Thrush isn't even a Catharus). Still it's too early to expect Gray-cheeked so it may yet pick up.

Still, it was a decent mix of earlier and mid spring birds - Black-throated Green Warblers were in a couple of places, but there was also Canada Warbler. Red-eyed and Blue-headed Vireos. Along the point there was my second Summer Tanager for the year - certainly the only year when I've seen two in the park. There were also tame Canada and Magnolia Warblers, American Redstart - the relatively warm area along the Point was the most active part of the Ramble, perhaps reflecting a cool start to the day. Two good birds were in the Evodia Field area: a Ruby-throated Hummingbird and a Black-billed Cuckoo. I was alerted to the Cuckoo by other birders and was frankly amazed when it was chased out of the tree by another Cuckoo ! We rarely see multiple Cuckoos in the park, and when we do we really don't see that sort of territorial interaction. I assume the second Cuckoo was also Black-billed but I wasn't able to relocate it. Turns out this was my first Black-billed Cuckoo in a few years. I usually have better luck with Yellow-billed, although they really aren't that much more common.

Following up on a sighting of more than one Cape May at the Bethesda Fountain I wandered south of the boathouse - something I rarely do now but it used to be part of my regular route into the park when I lived on the UES in Manhattan. I was lucky enough to hear a singing male and after a little search did get onto it. A park employee showed me two roosting Raccoons, and later in the day I saw two more near the Upper Lobe - 4 being the most I've ever seen in one day in the park. Despite culling due to rabies infection they still seem to be present.

There was also a Blue Grosbeak - another park rarity - that I didn't see after it was initially found at Cherry Hill. At that point in time (early afternoon) the crowds would probably scare away most wild birds. (Probably the same bird was found the subsequent day at Strawberry Fields).

CPK 5/3 (Acadian, Cape May)

I often feel like Accuweather let the 16-year old interns play with the forecast, so I wasn't totally surprised on Monday evening to see that Sunday's forecast for the week was wrong and Tuesday had prospects for a good migration day.

And so it was.

Entering Strawberry Fields at 7:15am I saw three Great Blue Herons migrating north. Isn't that a little late for them ? I had Great Blues migrating over the ocean on 3/26. Also in Strawberry were a lot of Gray Catbirds (as in: 7 in one small tree, many elsewhere). Outnumbering the Catbirds were White-throated Sparrows, which were there in the hundreds. Common Yellowthroat also put in a strong showing today too, and I saw at least twenty.

There were rarities about, but I only put my eyes on a few really interesting birds. The high point for me was an Acadian Flycatcher in Strawberry Fields (greenish, long-billed, long-primary projection). Acadian was my #1 park nemesis bird for many years - I've heard a few over the years - but compared to the Least Flycatchers I saw later the difference was quite marked. Marked, that is, for an Empidonax. Other nice birds included multiple singing White-crowned Sparrows (never common there), Cape May Warbler, Hooded Warbler. I also picked up Rose-breasted Grosbeak and American Redstart as year birds along with the Cape May Warbler, Acadian and Least Flycatchers. One of the better nn-FOY birds was Louisiana Waterthrush which stood out since the supercilium was indeed "the whitest thing on the bird". Lots of Northern Waterthrushes too. 17 warber species in all - pretty good going for a day originally forecast as rainy.

Backyard Monday

Watching the yard in Ewing on Monday morning was quite productive: the Yellow-rumped Warbler(s) were singing their unmusical warble and I could hear a distant Black-throated Blue Warbler song and hints of an even more distant Northern Waterthrush (uncertain). Then I spied an Ovenbird, only a few feet from my property line (and therefore sadly not on my full yard list). Finally two Pine Siskins turned up at my feeders, which I'm still running as I get through the last of the season's seed. Sadly from the way the House Wren is singing it still lacks a mate, but with migration ongoing perhaps one will arrive soon.

Good Weekend Part 2, May 1st


Following on the heels of Saturday, Sunday was slower but still pretty good. First interesting bird of the day was a Worm-eating Warbler at Balcony Bridge. I got a brief glimpse of what I believed to be the Varied Thrush (flushed by birders approaching too closely, yet again), then I got a tweet about a Bay-breasted Warbler in the Ramble. I got a brief look at that, and while trying to relocate it found a Blackburnian Warbler. After Nashville being a first-of-year bird the previous day there were several singing males in the Ramble and I saw a few individuals. While at the Bay-breasted I heard of a Yellow-throated Warbler elsewhere, and while unsuccessfully pursuing that I was told of a Summer Tanager. Summer Tanager is pretty rare in Central Park since it's north of the breeding range, but after a little searching it proved to be very active and not all that difficult to observe.

As the time approached noon I decided to check out Tanner's Spring which was initially quiet but had a brief flurry (N. Parula, Black-and-white Warbler, Black-throated Green Warbler, Nashville Warbler, Yellow-rumped Warbler) followed by another quasi-rarity - an Orange-crowned Warbler. Hermit Thrush and Veery were here (I saw Wood Thrush near the Varied Thrush spot). Then after leaving Tanner's intending to go home I spent at least an hour along the south side of Turtle Pond where the Summer Tanager was flycatching bees in the tall oaks and giving excellent views. I also added Eastern Phoebe and Canada Warbler for the day here.

Good Weekend Part 1, April 30th


As Chris pointed out, what you don't normally get is multiple Blackburnian Warblers on April 30th. And yet here one was, singing 20 feet over my head. The day had started cloudy and slow, although with pockets of activity. When the sun came out the Ramble lit up in terms of migrants: Veery, Wood Thrush, Blue-winged Warbler, Blackburnian Warbler, Nashville Warbler, Chestnut-sided Warbler, Magnolia Warbler, Cerulean Warbler, Red-eyed Vireo were the first-of-year birds. The Cerulean, while typically high, was quite vocal and gave decent looks.

I ended up with 16 warbler species, which is rather a high total for April, especially since I was carrying the camera. Cape May and Bay-breasted were reported from the north of the park, Worm-eating from the Ramble, so the multiple observer total was comfortably in the 20's.

Princeton - Hooded Warbler and Solitary Sandpiper

Although striking out on the Virginia Rail that was reported the previous day, a morning visit to Princeton's Institute Woods was quite interesting early. There wasn't a big migration there, with low numbers of warblers, but there were one or two interesting birds. On the pond: Great Blue Heron, Tree Swallows and two Solitary Sandpipers. The latter were new for the year to me. Along the drive toward the water plant were Baltimore Oriole, Yellow-rumped Warbler, Yellow Warbler and Blue-gray Gnatcatcher at the pond and off in the woods were singing House Wren, Ovenbird and Common Yellowthroat. However the best bird of the day was right back at where I parked my car - a female Hooded Warbler moving purposefully through the low undergrowth in the woods but showing itself clearly for a few seconds before darting across the road and vanishing.

Central Park 4/24 - good migration

On about as good a migration day as I've seen as early April 24th, a warm day following a wet day filled the park with migrants. Most of the migrants were Black-and-white Warblers (all male) and Yellow-rumped Warblers, but I did come up with 12 warbler species by the time I left around 1pm.

In the Maintenance Field things started off slowly, with two Brown Thrashers, Common Yellowthroat and Chimney Swift (first-of-year for me). Then Hermit Thrush and Northern Flicker put in an appearance and I had a brief look at Northern Parula flitting from tree to tree. Around Azalea Pond things were more active with multiple B+W Warblers and Yellow-rumped. My only Palm Warbler for the day passed through. Then I found by chance a silent Yellow-throated Vireo, for the longest time my only vireo of the day but I was to add Blue-headed Vireo later on. Northern Waterthrush was singing at Azalea Pond and there were several around including a very vocal one at the Upper Lobe. Near the Upper Lobe I also found a very mobile singing Yellow Warbler along with silent individual Blue-winged Warbler and Great Crested Flycatcher. Over at Sparrow Ridge (Sparrow Rock) near Tanner's Spring I found two Field Sparrows, a Black-throated Green Warbler and located a vocal Baltimore Oriole. Then up in the small flat area between Shakespeare Garden and Belvedere Castle I saw both the reported Hooded Warbler (first year male, by appearance) and tracked down the first year male Orchard Oriole by its chatter. The final hurrah for the day was a singing Black-throated Blue Warbler in the Oven.

Looking at the sightings logs I keep online, the Yellow-throated Vireo was by far my earliest one - previously May 1st was my early date. But the Black-throated Blue was more or less on time (my early date for that is the 20th). But there's still a lot of spring to come.

Princeton 4/18

With the prospects of a better migration day on Monday, I spent a little time at Princeton's Rogers Refuge before work. Along the road were several Yellow-rumped Warblers along with Ruby-crowned Kinglet (singing), Brown Creeper, Yellow-bellied Sapsucker, Eastern Phoebe. Near the pond I had a singing House Wren and back toward the car a Carolina Wren. A pair of Wood Ducks were on the pond.

The Lesser Calendines are in full bloom here, carpeting the ground in many places in an attractive display. Shame then that they are a nasty little invasive and crowding out the native species.

Central Park after the deluge, 4/17

Saturday ended amidst a storm of epic proportions, which cleared out too late to provide much of an overnight migration. So while I traveled into Central Park on Sunday I had to work hard to see any migrants at all. I came up with a single drab female Pine Warbler for the new world warbler list, although it was perfect habitat for Waterthrushes or Rusty Blackbird given the amount of water in the Ramble. Most interesting bird for me was an immature Sharp-shinned Hawk sitting in the Evodia Field, which showed little interest in making a pass at the American Goldfinches working a way at the last remaining feeder.

Princeton: Bittern, White-eyed Vireo 4/14

A quite cooperative American Bittern had been at Princeton's Rogers Refuge most of the week. After a quick check on Monday, when I found only a few Wilson's Snipe, I returned on a warm Thursday evening where I found the bird out in the open at the edge of the phragmites. Not a bad bird for NJ. I also saw one Wilson's Snipe again as it flushed from further back in the pond.

Additional birds were Wood Duck, Blue-gray Gnatcatchers and a White-eyed Vireo. The vireo is noteworthy because my personal early date for WEVI in the north-east was April 22nd 2008 (Sandy Hook), so this bird was 8 days early.

Migrant yard birds Saturday 4/9

After a week away working at Brookhaven National Lab, I returned home to see that spring had progressed in my absence. On Saturday morning I was watching feeder birds and thought that the House Finches looked odd. On retrieving my binoculars the birds were still there and proved to be two male Purple Finches - a first for the feeders, and for my year list, although they've flown over the yard before. The finches stuck around throughout the morning. Another first-of-year was Chipping Sparrow, which had clearly had a major influx during the week from other NY/NJ reports. Dark-eyed Junco numbers seemed to be down, so possibly some have moved on.

Two FOY's before even leaving the house. Although I was still lethargic from the Brookhaven trip I did head out to a local birding spot. Plainsboro Preserve is an old gravel pit with surrounding woodland and farmland. The visitor center had held a good collection of US birding travel books but their selection was poor this time - they've clearly stopped stocking them. At the feeders were a predictable mix of molding American Goldfinch, Brown-headed Cowbird and Red-winged Blackbird. Tree Swallows have also moved in en masse this past week and several were staking out nest boxes. I also found Golden-crowned Kinglet, Hermit Thrush (FOY) and Eastern Phoebe but the preserve was relatively quiet, as is typical here. The lake can sometimes pick up Common Loon but all there was were a few Canada Geese and two Mallards.

Redpolls


Common Redpolls were forecast to be an "invasion bird" this winter. And invaded they have, but they started invading really late in the winter, around February. It's not likely that they are still heading south, but there are some lingerers around. Two such birds turned up at the Central Park feeders and I went to see them on April 3rd. I found one adult male and a much drabber bird that on checking my photos turned out to be a first winter male. They didn't stick around for long (and certainly not close to as long as the long-staying Varied Thrush, still present in the park on April 14th).

Snipe in Piscataway 3/27


While recovering from the pelagic and associated drugs, I wasn't disposed to venture too far afield, instead limiting my sights to Piscataway, 20 miles to the north, and a Wilson's Snipe that had been in a park there. Just a single bird - and I wonder how these individuals elect to go their own way - and one that was sheltering in a wet area with surface water surrounded by Canada Geese. In fact it was having to dodge the geese as the latter wandered around. It was a little skittish, and with the number of (on-leash) dog walkers it's probably not much of a surprise.

This was a nice riverside park with some woodland, and I picked up Hairy Woodpecker and Northern Flicker for the year, in addition to the expected flocks of Robins and Canada Geese.

I stopped at Griggstown Preserve on the way back just as a monitoring stop en route to my favored plant nursery and found nothing, but the grassland hasn't yet bounced back from winter.

Uneventful "Inshore" Pelagic 3/26

I don't normally go on Pelagics without good reason, since I'm prone to getting seasick. I had balked at a genuine winter pelagic since the high temp was in the high teens Farenheight. However I rolled the dice on this Pelagic run by See Life Paulagics and found it to be almost totally futile - nothing I saw was something I couldn't see on/from land (and for the most part already had), although some of the views were better. For the life of my I cannot understand why this outfit always runs pelagics with NJ and NY trips on the same weekend, unless they're using the Saturday trips to scout for the Sunday trips.

Highlights: Iceland, Glaucous and Lesser Black-backed Gulls spending time at the back of the boat, somewhat of a regular pelagic thing; lots of Razorbills and some of them in breeding plumage.

Lowlights: only one year bird (the Glaucous); all the Razorbills were rather distant; NO other alcids (murres, puffins, dovekies); NO Kittiwakes; NO Fulmars; and the Gannets were relatively uncommon and all adults. Nothing on the water near the boat save gulls and a few Gannets.

The trip started off well - a Peregrine on the highway bridge, and coming north out of Belmar to Sandy Hook there were large numbers of scoters (Black, Surf and a few White-winged) off Sandy Hook. Which is where we picked up the persistent first winter Glaucous Gull in rather worn plumage. That bird followed us for a while, including the point where we turned south-east toward the "mudhole". When the Glaucous left an immature Iceland Gull joined us briefly. From the turn and for the first few miles we picked up a lot of Razorbills, most distant, but absolutely all of them in flight - if they saw us within several hundred yards they left the scene. A few of the closer ones (close enough that I could pick out the white stripe on the bill) had visible breeding plumage but most appeared to be in basic plumage. As we got further offshore the activity dropped off precipitously and so there were long stretches of total boredom. At about hour 6.5 (of 8) we found a group of gulls around some trawler (scallops?) and picked up adult Iceland and shortly afterwords also second cycle Lesser Black-backed, then after that a brief visit with third cycle Lesser Black-backed. But overall it was 2 hours of good start and 6 hours of total tedium.

Migration novelties were a flock of 7 Great Blue Herons, far enough from land that they must have set off on faith or some sixth sense heading for Long Island , a single Great Egret even further out, and a Wood Duck that I missed but was the furthest out of all (but at least it can set down on the water).

Note to self: no more late March pelagics, at least not with this lot, barring a lot of evidence to the contrary. Subsequent Atlantic pelagics should probably be off MA or NC, or perhaps a real deep winter pelagic again.

(I haven't seen the results of the subsequent day's pelagic, but given the lack of noise about it on the lists I think it had much the same results).
