Thayer's Gull

 The fun gull build-up continues (surely that Mew Gull is just around the corner, right???).  A young Thayer's Gull flew in to a limited amount of time I had at Tiscornia yesterday.  Fortunately it landed since I was too slow to extricate the camera from the coat layers initially.

Perched it'd be easy to blow off as just another Herring Gull.  It has a small round head, and a considerably shorter bill than the Herrings though.

Here's a couple views of the Venetian blind primaries.

And while Thayer's is fairly Herring-like on top, it's still a white-wing (and my first one of the fall) below

Technically Thayer's is lumped in as a subspecies of Iceland Gull in current taxonomy, but still a fun form to see nevertheless.
