We surveyed raptors on Espíritu Santo Island, Gulf of California, bimonthly from November 1998 to October 1999. Visual surveys averaged 64 hours per visit. We collected two Elf Owls by mist net. Of the ten species of raptors recorded, five are resident (Turkey Vulture, Osprey, Red-tailed Hawk, Great Horned Owl, and Elf Owl), two are common visitors (Peregrine Falcon and American Kestrel), and three are rare visitors (Northern Harrier, Harris’ Hawk, and Golden Eagle). Four species were previously unrecorded on the island (Northern Harrier, Harris’ Hawk, Golden Eagle, and Elf Owl). Of the ten species, three are protected by the Mexican government.
