觀察細節
Previously reported today. Slightly larger than Ring-billed Gull, dark mantle, yellow bill with red spot, all swimming together with RBGU flock, between tower and Metlife buildings. Got very brief view in good light with 30x scope, but a soaring Bald Eagle spooked the flock. The gulls landed closer but in the glare of the afternoon sun. For once, I wished it was cloudy! I moved down to the dock to get better angle and found good long looks at 7 LBBG: 6 adults 1 immature, all but 1 adult swimming together in the raft of RBGU at 15:50. The seventh adult was in another part of the flock. Photo shows 2 adult LBBG and 1 immature LBBG along with 3 RBGU.
