One of the hopes for our time at the Salton Sea was to see reasonable numbers of Thayer's Gulls. These hopes were soured a little when there appeared to be very few reports of Thayer's on the South-eastern California RBA but with a little persistence my group and I found one on Jan 14th, at least nine on Jan 15th, and then over ten during a solo effort on Jan 18th. Most were first-year birds, but I managed to find all the age classes including a nice adult with an American Herring Gull at Red Hill on Jan 18th. This post details some of the first-cycle birds.

Wonderful post! Great images! Very instructive. I downloaded a couple of images to see whether I could get a better look at the primaries and the tertials using Photoshops Shadows/Hightlights function.
