Gulls (Laridae)

Yellow-footed Gull (Larus livens) - HBW 3, p. 608

French: Goéland de Cortez German: Gelbfußmöwe Spanish: Gaviota de Cortés

Taxonomy: Larus occidentalis livens Dwight, 1919, San José Island, Baja California.
Until recently treated as a race of L. occidentalis, but differs in vocal repertoire, particularly its lower-pitched long call. Some authorities consider it more closely related to, and perhaps derived from, L. dominicanus. Monotypic.

Distribution: NW Mexico, in Gulf of California; rare in S California, USA.
