Isla Guadalupe (29° N, 118° 17' W) is located off the west coast of Baja California, México. The history and status of its avifauna, as well as a brief description of the island, have been given by Jehl and Everett (1985). Additional recent observations have been reported by Dunlap (1988) and Oberbauer et al. (1989).
In this note we report on birds observed on and near Isla Guadalupe on 23 November 1989. Our time ashore lasted from 1000 to 1500 hours, during which we traveled about 60 km (round trip) by car from Melpomene Cove, at the southern end of the island, to the large barren area north of the remnant of the cypress forest, in the high central region. En route we also visited Campamento Oeste.
