MWM Posted November 18, 2022 Share Posted November 18, 2022 Thinking Great Black-backed or Herring for the juvenile, and either Lesser Black-backed or Slaty-backed for the other gull? Quote Link to comment Share on other sites More sharing options...

MWM Posted November 19, 2022 Author Share Posted November 19, 2022 Thanks for the reply, what details tell it's a Lesser Black-backed instead of Slaty-backed? Even looking at Sibley's I don't really see much difference (except for the legs, and a couple inches in size). Quote Link to comment Share on other sites More sharing options...
AlexHenry Posted November 19, 2022 Share Posted November 19, 2022 Slaty-backed is much rarer. Size (relative to herring gulls) and shape look like a Lesser Black-backed. 4 Quote Link to comment Share on other sites More sharing options...
MWM Posted November 19, 2022 Author Share Posted November 19, 2022 Thanks, the reason I was checking is there was a Slaty-backed reported at the same location a few days ago. However this location usually gets a couple Lesser Black-backed each winter. Quote Link to comment Share on other sites More sharing options...
