Heavyweight contendahs

Silver Beach this morning had a decent selection of gulls.  I don't find either Glaucous or Great Black-backed to be as attractive as their smaller sister species, but it's fun to get them together in the same frame.

Sibley has Glaucous at just over 3 pounds and the rangier Great Black-backed at about 3 1/2.  The Glaucous probably wasn't used to having to give ground.

The full adult flew right past.

The Black-backed did eventually as well.

There were a total of 4 Great blackbacks present.  This one's subadult bill but near adult wings probably makes this a 3rd winter bird.

The heavy all dark bill and white rump of the first winter bird generally stand out as well.
