MWM Posted February 26, 2022 Share Posted February 26, 2022 Taken today in Geneva NY, looks like a Greater but with yellow legs. (One pic has regular pink-legged Great Black-back for comparison). Quote Link to comment Share on other sites More sharing options...
Sneat Posted February 26, 2022 Share Posted February 26, 2022 Looks fine for a Great Black-backed Gull to me. Bill is larger than I would expect for a Lesser Black-backed Gull and back just slightly darker. There is also not a noticeable size difference between the two birds in the comparison photo, a Lesser Black-backed Gull would be significantly smaller than a Great Black-backed. The legs are tinged yellow, but I would expect more bright yellow to conclude Lesser Black-backed Gull, especially when the individual has a clean unstreaked head. 3 Quote Link to comment Share on other sites More sharing options...
RobinHood Posted February 26, 2022 Share Posted February 26, 2022 Agree with Greater, bill size and too dark for Lesser. 1 Quote Link to comment Share on other sites More sharing options...

MWM Posted February 27, 2022 Author Share Posted February 27, 2022 I was checking out Great Black-backed Gulls on Ebird, some of their files pics show adult birds with pale yellowish legs? Wonder if it's a Breeding/Non-breeding trait? 1 Quote Link to comment Share on other sites More sharing options...

Listening to a presentation on Gull ID by Amar Ayyash and he just mentioned, 2-3% of Great Black-backed Gulls have yellow legs. 3 Quote Link to comment Share on other sites More sharing options...
