觀察細節
1st time seeing in North America. In field across from dump. Black backed gulls but not as dark as Greater Black Backed. Barely bigger than adjacent Ring Bills. 1st bird had some streaking on head although head was tucked in, bird was sleeping so couldn't see legs. 2nd bird had head tucked in. Showed darker mantle then adjacent gulls, Hard to determine leg coulour in lighting. In photo it appears legs are not as yellow as adjacent Ring Bills, however the legs also don't appear pink like Herring gull in same pic. Pics aren't greatest but should show enough for confirmation.
