The University of Arizona's Bird Collection containing over 18,000 cataloged specimens is the largest bird collection in the state. The Museum maintains a traditional study skin collection as well as a wing and tail, skeletal, and nest and egg collection. Originally begun in 1884 by Arizona resident Herbert Brown, the bird collection has seen periodic growth over time due to the efforts of some of the nation's best ornithologists. The Bird Collection remains dedicated to preserving the treasures of the region, while also promoting education and awareness to the public.
