zoutedrop Posted February 6, 2020 Share Posted February 6, 2020 Please validate these birds as Great Black-backed Gulls. January, 2020 in Newfoundland Quote Link to comment Share on other sites More sharing options...
Jerry Friedman Posted February 6, 2020 Share Posted February 6, 2020 Until somebody who knows something about gulls shows up, I'm going to pass on the first and suggest that the second and third pictures look good for Greater Black-backed to me, with those fancy black-and-white patterns. However, the fourth, with the back and wings lighter gray than that wingtips, makes me think about Lesser Black-backed. If anyone disagrees, ignore me.

akiley Posted February 8, 2020 Share Posted February 8, 2020 They're all Great Black-backed. The last is too bulky in shape and bill for LBBG. Mantle shade looks fine to me, although it could be darker. See a bird like this one: https://ebird.org/checklist/S53857375 2 Quote Link to comment Share on other sites More sharing options...
