Fwd: [eBird Alert] Kings County Rare Bird Alert **THAYER'S gull reports

"If we had not had a Christmas Bird Count in those early years, we would not have as strong an understanding of long term bird trends. Many of these changes take place gradually." - Chan Robbins, legendary biologist, retired USFWS employee, and creator of the North American Breeding Bird Survey

- Reported Dec 15, 2025 13:15 by Linda Ewing
- Prospect Park, Kings, New York
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&q=40.6602841,-73.9689534&ll=40.6602841,-73.9689534
- Checklist: https://ebird.org/checklist/S288746767
- Comments: "Found yesterday by Ant, who'd been patiently searching for this bird to return (they'd had it last year). Very challenging to ID; I benefited from KZ's knowledge (and scope). Best field marks, for me, were the bright pink legs & feet (deep pink, almost red); dark eye; and pale underwing (seen well just once). More round-headed than herrings. Seen variously on ice, in water, and in flight."
