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.

Six Mile Run, July 31st

To finish off a month after a couple of weeks idle due to surgery I visited Six Mile Run to see how the postbreeding situation was. I found that they'd mowed a portion of the main field to the north of the grassland path - this might be for habitat regeneration. Best bird was a juvenile Blue Grosbeak, flocking with Field Sparrows (juveniles here too) and a couple of very worn adult Song Sparrows. A few male Indigo Buntings were hanging around, and two were singing. I thought I heard a brief snippet of Grasshopper Sparrow song but didn't see any so I might have been mistaken. The habitat was still in flower, particularly with some thistle species, and Eastern Tiger Swallowtail butterflies were relatively numerous. Orchard Oriole, Cedar Waxwing, Eastern Bluebird, House Wren and American Goldfinch were also around.

Contrast this with Griggstown which had no flowering plants within hundreds of yards of the parking lot, no butterflies, and virtually no birds. Franklin Township have really f*cked up the habitat maintenance at Griggstown and actually managed to degrade it substantially.

Six Mile Run, Griggstown, Pole Farm: May 30th

Results for Six Mile Run (Franklin, NJ) were almost identical to the visit on the 26th:

The most cooperative bird was the same Willow Flycatcher, actively marking territory.

Dropping down to Griggstown the grass has grown up but there was somewhat of a dearth of singing heard from the parking lot. Orchard Oriole and Rose-breasted Grosbeak were fly-bys but I didn't linger there.

Instead I headed to Pole Farm to check for Bobolink, which were there in modest numbers (4-5 males, 1 female) along with Eastern Meadowlark and Willow Flycatcher. Despite the new kestrel box, I didn't see any raptors.

Six Mile Run, May 26th

A quick hour-and-a-bit around the main field trails (east of the parking lot) before work. Three male Willow Flycatchers (one on marginal territory but the most active singer), two Orchard Oriole males (one first spring), two or three singing Grasshopper Sparrow males were the highlights of this trip and not coincidentally also year birds. Otherwise a worthwhile but totally predictable list of species. The biggest miss was Indigo Bunting, neither seen nor heard.

SIx Mile Run and Griggstown, July 11th

For the first bit of birding I'd done since the MN-ND-WY and Britain trips, I went to Six Mile Run and Griggstown to get a feel of mid-summer birding there. I only got to Six Mile Run by 9am so had to compete with bicyclists for trail usage. Nevertheless I got a pretty reasonable sample of bird life there: Song, Field and Grasshopper Sparrows, Willow Flycatcher, Yellow Warbler, Eastern Bluebird, Indigo Bunting, American Goldfinch - these are all pretty representative of the species there and some of them were still singing including one Grasshopper Sparrow. Perhaps they were starting to worry about second broods, which is probably what all those singing House Wrens are doing (like the one in my back yard).

Griggstown, by contrast, was quiet although it was even later in the morning. Griggstown is less of a native grassland preserve right now than a native shrub and weed preserve and the amount of actual grassland probably translates into reduced diversity. So I didn't linger there and concentrated on trying to fit a modest-sized Buddleia (Butterfly Bush) in my Honda Accord for the drive home from the Belle Mead co-op. This place are good about stocking native plants and many of the perennials in my attempt to make the new place more wildlife-friendly have come from there.

Griggstown and Six Mile Run, May 30th

I really haven't spent any time at my two local grasslands this spring, so I rectified this on Saturday morning by going to Griggstown Native Grassland Preserve and the nearby Six Mile Run, both on the east side of the D&R canal in Franklin Twp.

Griggstown was somewhat of a disappointment, since it held neither Bobolink nor any singing Grasshopper Sparrow and there was no Willow Flycatcher - I'm wondering if the successional nature of what's going on there may have something to do with it - the habitat has a different feel to Six Mile Run. I did see a smattering of usual species and a Red Fox: Song, Chipping and Field Sparrows, an Indigo Bunting, Orchard and Baltimore Oriole, Eastern Bluebird, Yellow Warbler and Common Yellowthroat and the inevitable Red-winged Blackbirds and Tree Swallows.

At Six Mile Run, there was all this and more. There were several singing male Grasshopper Sparrows, some of them obviously paired. There were two singing Willow Flycatchers (not obviously paired) and a pair of Great Crested Flycatchers in the parking lot. Best of all there was a Blue Grosbeak male a little further up the trail I usually take. The Willow Flycatcher shot is from Six Mile Run.

Princeton area Grasslands - May 7th 2008

After an uninspiring stint in Central Park on May 6th I decided to look locally on May 7th at three local grassland preserves: Griggstown, Six Mile Run and Negri-Nepote, all of which are in Franklin Twp which seems to value its open space in contrast to other localities.

Starting at Griggstown there were swallows looking for mud on the ground, including a Northern Rough-winged Swallow that dropped down into the parking lot. There were four Bobolinks around the parking lot, which left when I arrived, but I kept seeing male Bobolinks in the preserve - they weren't being vocal or displaying however. There were also (silent) Savannah Sparrows but I heard no singing Grasshopper Sparrows. Griggstown appears to be getting a slow start. Wood Thrushes were to be heard from the woodland, at least.

Next I went to Six Mile Run, where the usual Chipping Sparrows were in the parking lot and Brown Thrasher, Baltimore Oriole and Yellow Warbler were in the scrubby area nearby. One interesting thing was watching a female Yellow Warbler gather silk strands from a Gypsy Moth caterpillar tent for nest building. She visited various tents several times for this. In the fields Eastern Bluebirds, Tree Swallows and Field Sparrows are inevitable. Two Indigo Buntings were singing, along with a Blue-winged Warbler. Further down the trail I came across the first of four singing Grasshopper Sparrows - in fact the first one was a very brightly-marked male. Since they starting singing later in the morning it's conceivable that they hadn't started at Griggstown.

After Six Mile Run I went to Negri-Nepote, where a Prairie Warbler sang near the parking lot, another Grasshopper Sparrow at the first of the grasslands. At the freshwater pond there were Hooded Merganser, several Least Sandpipers, Solitary Sandpipers, a full breeding plumage Spotted Sandpiper and a Lesser Yellowlegs. The sun was high enough that I didn't waste time photographing them, but it was interesting to see how they use any little bit of water they can find. Near Negri-Nepote I noticed other undeveloped private land that looked like it could be good for grassland species, although the two lots on the corner of Skillman Rd right next to the preserve had For Sale signs on them.

Finally I visited Princeton's Institute Woods to check that there hadn't been a warbler dropout - apart from Rose-breasted Grosbeak and singing Yellow Warbler things were relatively quiet at 11am and I left without spending too much time there.
