Thayer's Gull (Larus thayeri), Pittsburgh Pt, Lake Havasu, Mohave County

This Thayer's Gull was discovered and photographed by David Vander Pluym on 09 November 2011

Casual in Az less than 15 state records

Shows the pale primaries from below caused by the inner webs being paler than the outer webs of the primaries. Small billed. Different from the Nov 21 bird because of the neat rows of brown on the under tail coverts as oppose to the more messy look of the Nov 21 bird.
