California Gull
Larus californicus
Summary 2
The California gull (Larus californicus) is a medium-sized gull (18 to 22 inches long), smaller on average than the herring gull but larger on average than the ring-billed gull, though it may overlap in size greatly with both. Adults are similar in appearance to the herring gull, but have a smaller yellow bill with a black ring, yellow legs, brown eyes and a more rounded head. The body is mainly white with grey back and upper wings. They have black primaries with white tips. Immature birds are also similar in appearance to immature herring gulls, with browner plumage than immature ring-billed gulls. California gulls have been spotted at the COSA from February to May and in July
