A Heermann's Gull (Larus heermani), photographed at Gazos Creek Beach, just north of Franklin Point. Gazos Creek Beach is part of Año Nuevo State Reserve in coastal San Mateo County, CA.
Much lighter/brighter than others I have seen.
San Pedro Riparian National Conservation Area south of Hwy 92.
Enjoying a buffet of insects at the Green Things nursery
Not 100% sure on this ID, but it was about the right size, etc. for a female INBU, and there were a lot of males and more easily identifiable females at the CA that day.
