The Museum acquired its first collection of scientific importance when Frank Stephens, the first director of the museum, donated his bird and mammal collection to the museum in 1910. The holdings have continued to grow in size and significance, with subsequent addition of specimens collected by staff members and others, including Laurence M. Huey, Sam G. Harter, May Canfield, J. E. Green, Joseph W. Sefton, Jr., R. C. Banks, J. R. Jehl, Jr., A. M. Rea, and P. Unitt, as well as acquisitions of important collections, primarily that of Stanley Jewett.
Birds: approximately 46,700 skins (both flat and conventional or "round" skins); 8050 skeletons.
Taxonomic coverage: Skins of almost all species of North America, including Baja California. The full range of variation (geographic, seasonal, sexual, developmental) of many southwestern species is represented. Passerines with complex geographic variation are covered in greatest depth. The skeleton collection is taxonomically broad, covering over 90% of all bird families. For groups not occurring in western North America, it is based heavily on specimens received through the San Diego Zoo. The waterfowl, parrots, pigeons, starlings, and babblers are among the large families especially well covered.
Type specimens: There are 48 primary type specimens (holotypes and syntypes).
Mammals: About 23,450 specimens, about 20,000 skins, almost all with accompanying skulls. About 960 complete skeletons, including virtually all species of southern California and a broad variety of marine mammals, both pinnipeds and cetaceans. The mammal collection was first accredited by the American Society of Mammalogy in 1975 and most recently re-accredited in 1995.
Taxonomic coverage: Almost all species of western North America, including Baja California. Rodents are by far the group best represented, with over 18,250 specimens. Other notable components are 1645 specimens covering 41 species of bats, 221 specimens covering 25 species of cetaceans, and 142 specimens covering 14 species of pinnipeds. Of mammal families worldwide, 58% are represented.
Type specimens: Holotypes of 87 subspecies and 2 species.
Geographic coverage (both birds and mammals): California, Oregon, Arizona, and Baja California are the states best covered.
The collections are constantly growing on the basis of specimens received through the public, wildlife rehabilitators, the San Diego Zoo, and the department's own research.
