The Laysan Albatross, Diomedea immutabilis, the most abundant species of albatross in the north Pacific (Pitman 1985), has recently expanded its breeding range into the eastern Pacific. In May 1986, adults with chicks were discovered on Isla Guadalupe, 230 miles west of Baja California, Mexico (Dunlap 1988), with nesting continuing there at least through 1988 (Oberbauer et al. 1989). Courtship has also been reported at two other sites off Mexico: Alijos Rocks, 185 miles west of Baja California (Pitman 1985), and Isla San Benedicto, in the Islas Revillagigedo, about 230 miles south of the southern tip of Baja (Pitman 1988).
To date, only one account of the Laysan Albatross in the Gulf of California has been published: a single bird seen 5 May 1982, east of Cabo San Miguel, Baja California Norte (Wilbur 1987). Here we provide additional records gathered during fieldwork in the northern Gulf of California.
