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.
