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.

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.

Griggstown Preserve, October 13th

Typical for a day in mid October, Griggstown Native Grassland Preserve was swarming with Savannah Sparrows. There were also good numbers of Swamp Sparrows and various other expect sparrow species. Two American Kestrels, a Northern Harrier and a late Bobolink rounded out the selection.

Griggstown Preserve, August 10th

A late summer visit to Griggstown after several weekends bogged down with house-hunting revealed no great surprises. Song Sparrows, Field Sparrows and a few Indigo Buntings were in evidence. The Red-winged Blackbirds had moved off breeding territories although a few appeared to be staging at the cherry trees over toward Canal Rd. Also there were two Ruby-throated Hummingbirds, chasing each other. There were a few Bobolinks - either all females/juveniles or the males had already molted. I'm not sure if they bred here this year, but at the very least they were using it in late summer - a promising sign. Other species were several Eastern Bluebirds including juveniles (despite the wet and cold spring), Barn Swallows, House and Carolina Wrens, Common Yellowthroat, Brown Thrasher, Eastern Towhee, Orchard Oriole and heard Baltimore Oriole. A loud begging juvenile Red-tailed Hawk was making its way around the edge of one of the fields and there was also a large (female?) immature Cooper's Hawk being far more unobtrusive.

Very little singing, as you might expect, apart from a Song Sparrow or two and an Indigo Bunting.

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.
