Thayer's Gull 1st cycle (2CY), May 21 2012, Anchor Point, Kenai Peninsula, Alaska. Picture: Tom Johnson.

Presumed Thayer's Gull (worn/ bleached first cycle) - obviously daintier than the hulking Glaucous-wingeds and Glaucous-winged x Herring hybrids present, with a noticeably slimmer bill.

Bird in complete moult: P1-P2 dropped. Note moult in flank and side of breast with new feathers obvious colder grey.
