Lesser Yellowlegs, Governors Island

I had my first Greater Yellowlegs in April 2013 at Sherman Creek. Since then I have had the species at least once every year — three times in 2017. Given that the Eastern population of Lesser Yellowlegs is somewhat larger than that of Greater, and that New York City shorebirding hotspots in other boroughs record relatively similar numbers of these birds, it is a mystery why Lesser Yellowlegs is so rarely observed in New York County (Manhattan).

Prior to yesterday, there had been only two eBird reports of Lesser Yellowlegs in Manhattan since 2010 — an unchaseable flyover in April 2010, and an appearance on the mud flats of Inwood Hill Park in July 2016 that was entered a couple hours too late to chase before the tide rose.

Yesterday, August 24, the fenced-in puddles on the southeast side of Governors Island, which have been hosting a variety of common shorebirds since spring, finally produced a rarity. After 3 p.m. Gabriel Willow of NYC Audubon found a Lesser Yellowlegs feeding among a mixed flock of shorebirds that included Least Sandpiper, Semipalmated Sandpiper, a single Solitary Sandpiper, and Killdeer.

With the last ferry to Governors Island leaving on weekdays at 4:15 p.m., I could not do a same-day chase.

Today I took the first ferry of the morning, at 10, hoping that the Lesser Yellowlegs did not join in what was a large overnight flight. To my delight it and all the other species mentioned above were still present.

Autumn Surge

Since my last post, on September 5, I had what seems to be my best-ever September and October, completely turning my year around. On this table I have bolded the names of species reported by relatively few birders.

Year
bird Date Species Location
183 6-Sep-16 Connecticut Warbler Central Park
184 9-Sep-16 Virginia Rail Central Park–The Ramble
185 11-Sep-16 Red-shouldered Hawk Central Park
186 12-Sep-16 Red-headed Woodpecker Central Park–The Ramble
187 19-Sep-16 Green-winged Teal Central Park–Harlem Meer
188 21-Sep-16 Northern Pintail Central Park–Turtle Pond
189 25-Sep-16 Vesper Sparrow Central Park–North End
190 27-Sep-16 Clay-colored Sparrow Central Park
191 28-Sep-16 Marsh Wren Central Park
192 1-Oct-16 Nelson’s Sparrow Randalls Island
193 3-Oct-16 Saltmarsh Sparrow Randalls Island–NE fields and shoreline
194 3-Oct-16 Eastern Screech-Owl Inwood Hill Park
195 6-Oct-16 American Wigeon Central Park–Harlem Meer
196 8-Oct-16 Eastern Meadowlark Central Park–Great Lawn
197 9-Oct-16 Wilson’s Snipe Randalls Island–NE fields and shoreline
198 12-Oct-16 Blue Grosbeak Central Park–Wildflower Meadow
199 19-Oct-16 Yellow-breasted Chat Central Park–North End
200 20-Oct-16 Northern Harrier Randalls Island
201 23-Oct-16 Cackling Goose Inwood Hill Park–Dyckman Fields

Let’s go through the list quickly. The Connecticut Warbler stayed at its Pilgrim Hill location all day and was seen by 50+ observers. Those few who missed that one had many other chances, as at least six others were reported and chaseable. Similarly, the Virginia Rail stayed in the Ramble all day, wandering sometimes from the outlet of the Gill on the Lake to the fenced-in Swampy Pin Oak area.

Very few birders had Red-shouldered Hawk this fall, even though it is generally a common flyover migrant. East and northeast winds that prevailed for over two weeks during the height of September hawk migration made this species and Broad-winged Hawk difficult to get.

Only a handful of birders got and reported this first Red-headed Woodpecker of the season, but several others of the species showed up in October and lingered.

Green-winged Teal — at least two — lingered for weeks on the Meer.

This female Northern Pintail stayed on Turtle Pond for only a day, but many saw it.

I had the only eBird report of this Vesper Sparrow, and surprisingly, the species did not end up being seen my many. Last year one lingered for days at Locust Grove.

A Clay-colored Sparrow was seen by a handful of birders on the grassy hill east of Lasker Rink and immediately alerted, but I was minutes late in responding and the bird was not seen there again. I ended up getting a different one near Wagner Cove.

A Marsh Wren lingered for at least a few days on the southern shore of the Lake.

Both Nelson’s  and Saltmarsh Sparrow again showed up on the northeast marsh of Randall’s Island, as they usually do.

An Eastern Screech-Owl was seen and reported at Inwood Hill Park. It proved to be a difficult chase, taking hours, as little information was provided as to location. I eventually found the roost and stayed to hear it calling after sundown.

The female American Wigeon on the Meer looked so similar to the many transitional-plumage Northern Shovelers with which it associated that a few birders were unable to find it on their first try even after my Twitter alert indicated that the bird was on the eastern section of the water. It stayed for more than a few days and was seen by many.

Deborah Allen reported the Eastern Meadowlark on the Great Lawn with her birding group. I ran out to see it immediately. It did not linger for more than an hour. Other meadowlarks appeared in the North End and on Randall’s Island, but these were seen by only a few.

I ran out to Randall’s Island’s northeast shore to chase a Caspian Tern seen earlier in the day by Andrew Farnsworth. I did not get the tern, but my hour there was well-rewarded by a Wilson’s Snipe that flew across the East River from Queens and landed nearby on a ball field. There were no snipes reported in Central Park this fall.

I chased an Muscota Marsh Blue Grosbeak that had already been reported to have flown, as birds do sometimes return to good locations. This one did not. Nevertheless, within ten days another Blue Grosbeak was reported at the Central Park Wildflower Meadow, and with a little patience I got that one.

My first Yellow-breasted Chat of the fall was heard only, in the thick brush south of the Children’s Glade. I was delighted to get it, as I had spent many hours on multiple occasions trying to observe the well-reported Chat at Maintenance Meadow in mid-September. I ended up getting another Chat visually on the 24th. This one apparently remained in the area and took up residence in the vicinity of the Sparrow Rocks, just east of the West Park Drive at 82nd Street, allowing many to see it.

The Northern Harrier — bird #200 of my year — was flying low downstream on the East River.

The Cackling Goose was initially reported at the ball fields north of Spuyten Duyvil, after which it flew. I re-found it on the Dyckman Fields at the opposite end of Inwood Hill Park.

This excellent fall helped to made up for a poor winter and a disappointing shorebird season. I am looking forward to what November and December will bring.

 

 

 

 

 

Weather continues to discourage migration

Since the very promising Wednesday, April 17, of last week, we have had five consecutive poor birding days. Continued cold weather and northerly winds surely are to blame. By now we normally would be seeing great numbers of Yellow-rumped Warblers, but birders are tallying only one or two per outing. Last year these warblers were already abundant by the 17th.

The standout migrant so far has been Blue-gray Gnatcatcher. Last year this was a difficult bird to to observe all throughout spring migration. I believe I had only two during all of April. On Friday, Saturday, and Sunday, totals of three to six gnatcatchers were the norm among eBird lists that I checked, and my own counts were also in this range.

Other warblers have appeared, but perhaps only one or two birds across the whole of Central Park: Black-and-white Warbler, Yellow Warbler, and Northern Waterthrush, for example.

All three swallow species have been appearing on the Lake, along with a Black-crowned Night-Heron or two. I had my first-of-season Chimney Swifts on Sunday over the Lake.

I also had my first-of-year Red-breasted Nuthatch in Inwood Hill Park on Saturday (heard only), followed by a close-up visual of one in the North End on Sunday.

Conditions for migration may be briefly more favorable during the middle of this week. We will see!
