Excerpt from Bulletin of the Southern California Academy of Sciences, 1943, Vol. 42: Los Angeles, California The area covered in the present report includes El Segundo beach and sand dunes, Playa del Rey beach and salt marsh, and that portion of the Pacific Ocean, within a mile or so of shore, bordering on the Playa del Rey - El Segundo region. Because the ocean and salt marsh play such important roles in governing the occurrence of a large proportion of the bird life of El Segundo sand dunes, it was deemed best to include them in the survey of the avifauna. In preparing this paper, the objectives I have attempted to keep in mind have been to assemble and present information that would indicate: (1) the species and subspecies of birds occurring within the region, (2) the relative abundance and distribution of these forms within the area, (3) the factors determining the presence and habitat distribution of the various kinds, and (4) the annual cycle of activity of each kind in the region. The relative completeness of the present list is due, not so much to the observations of members of the El Segundo Sand Dunes Survey group as, to the fortunate circumstance that, in the early part of this century and up to 1923, members of the Southern Division of the Cooper Ornithological Club did a large amount of field work in this area. Their specimens, many of them deposited in the Los Angeles Museum, constitute an extremely valuable source of information on the birds of this territory, particularly as regards forms which are not readily identifiable in the field.
