影音備註

Center Gull is candidate #2 for Possible Iceland (Thayer's) Gull. Has darker eyes than the surrounding Herring Gulls; Herring gull seems to have yellow eyes for all but juveniles. This photo makes it clear how much darker the eyes are the the other gulls, which seem to have clearly yellow eyes.

觀察細節

Some immature gulls that were with the herring gulls, but possibly are something else, perhaps Iceland (Thayer's), based on darker eye coloration.
