I'm at a meeting, but here's another image from the boat trip to Bodega Canyon and Cordell Bank on 9 October 2016. This is an immature Sabine's Gull (Xema sabini). We were very fortunate that Captain Rick was able to maneuver the boat into position for wonderful, close-up views of this pelagic gull.
For comparison, the photo below shows the Black-legged Kittiwake (see last night's post) and the Sabine's Gull in the same view.
Sabine's Gulls nest in the Arctic, but winter in the tropics and subtropics. Not such a bad way to spend the year!
P.S. For views of adult Sabine's Gulls, and a little more information about them, review the post from 3 September 2013.
