National Bird Collection

The Division of Birds, National Museum of Natural History, Smithsonian Institution, houses and maintains the third largest bird collection in the world with over 640,000 specimens. Our National Collection, known in the ornithological literature by the acronym USNM (referring to our former name of United States National Museum), has representatives of about 85% of the approximately 10,000 known species in the world's avifauna.

This collection supports scientific research by resident staff and associates, as well as numerous visting scientists. Specimens are made available to researchers worldwide through collections visits, loans, and through our online database.

In addition to the Smithsonian staff, zoologists from the Patuxent Wildlife Research Center, U.S. Geological Survey are permanently stationed in the division and work closely with colleagues and specimens at the Museum. These specialists focus primarily on North American birds.
