Possible Slaty-backed Gull at Pt. Pinos, Monterey, 5 Feb 2007
This morning while walking the dog I stumbled upon two interesting gulls at
Pt. Pinos. One was a classic first-cycle Glaucous Gull, the other a
possible second-cycle Slaty-backed Gull. I was able to photograph both, and
I've posted photos here:
The bird was quite striking compared with the surrounding Western Gulls in
that it was very white-headed with an obvious pale eye. In flight the inner
primaries were pale and I could see a hint of the "string of pearls" caused
by the pale inner vanes on the outer primaries.
Comments are of course welcome. Here is an assortment of similarly aged
Slaty-backed gulls taken in Japan on 15 Feb 2001.
