2nd Cycle Thayer's Gulls from California

Below is a collection of 2nd cycle Thayer's Gulls photographed in central California in mid-January (2014). A week-long trip here allowed for good study of this species with some 600 individuals sighted, ~ 100 of which were second cycles. Also available are collections of 1st cycles, 3rd cycles and adults.
