Several of the previously recorded birds are quoted as from "the 

 Coronado Islands," though these are erroneously stated to be "in the 

 Gulf of California." 



Summary. 



Twenty-two species of birds are known from Los Coronados 

 Islands. Fifteen of these are indigenous, while seven are visitants 

 which breed elsewhere. Only six native land birds have been 

 found, of which the Bald Eagle, Raven, and Duck Hawk are birds 

 of long flight and general distribution. Two of the remaining 

 three are different in certain recognizable features from their 

 relatives on the adjacent mainland ten miles distant, being most 

 like those on San Clemente Island, six times as far away in 

 another direction. The non-indigenous species are all of wide 

 distribution along the Pacific coast of North America.
