Bird #5

IDs by Steve Hampton and Jon King

Bird #1 (small light colored) - pale Thayer's Gull

Bird #2 (larger bird) - Glaucous-winged Gull

Bird #3 - palish Thayer's (the size, structure, dark legs, and very long prim proj all point to Thayer's, in this case with a hint of "kumlieni" e.g., in the prim tips)

Bird #4 - Glaucous-winged Gull

Bird #5 - GW X smithsonianus hybrid (probably not F1 as it is generally very close to Herring, but the washed out feel and prims suggest GW was involved a while ago).
