Description:

 A large, bulky, extremely pale gull with dark eye and dark-tipped pink bill.

The bird was larger than the 100 Herring Gulls present.

The head and underparts appeared for the most part unmarked buffy or grayish white. There was light streaking, but this wasn’t readily noticeable.

The mantle had faint, widely spaced grayish bars. The wing coverts had what appeared to be faint grayish subterminal markings. The primaries and secondaries were seemingly solid translucent white. The uppertail coverts were barred with pale gray or buff, and the tail had faint barring, and slightly darker subterminal markings.

The eye was dark. The legs, which were hard to see most of the time, seemed pale flesh to me. The bill was a very distinctly pink, with a distinct dark tip.

 

 

 

Voice:

No voice was heard.

Similar species:

Other pale gulls are smaller. Albino/leucistic Gulls wouldn’t match this combination of features.

Photographs or tape recordings obtained?

Stills by me; digital photos by Dave Patton.

 

 

Previous experience with this species: 

1, seen 10 years ago. This was by far a better look.
