A large flock was here , with a few Western Gulls . Note here the yellow to olive legs , the dark eyes , and the red and black marking on the bill .
Full breeding plumage.
My best guess is that this is a California Gull transitioning from juvenile to adult plumage.
Tons of gulls that refused to get off the runway! Planes were landing and taking off pretty constantly, and the airport even set a guy in a truck to drive down the runway and try and chase them off, to no avail. They'd fly off a little ways and come right back.
Small flock, mostly immature.
