April 8, 2014 - Western Gull (Larus occidentalis)
Requested by: serotina
This gull is found on the West Coast of North America, in a more restricted range than that of most gulls. It is a marine gull, nesting on islands, including San Francisco’s Alcatraz Island. It is typically very aggressive at defending nesting territories and has been considered a nuisance because of this. Its varied diet includes fish, mollusks, seal and sea lion carcasses, and trash.
