While is it sometimes difficult to distinguish some gulls. For the Heermann's Gull Larus heermanni this is easy since it is the only gull with black feet. The black tip of its beek, both upper and lower, also helps. Finally, in flight the broad black tail band with white tips is also distinctive. Most of the Heermann's gulls on this page were from a colony many dozens at Mussel Shoals, Ventura, CA intermixed with Elegant Terns (see Elegant Tern). The 0 to 199 photos were taken at Moss Landing, CA
