The Great Basin Bird Observatory is an ornithological nonprofit organization based in Reno, Nevada. Founded in 1997, its mission is to conserve birds and their habitats in Nevada and adjoining regions through partnerships, applied research, and education. The Great Basin Bird Observatory was founded as a non-partisan conservation science organization. Its first, and for many years only, project was the first comprehensive Nevada Breeding Bird Atlas. For the atlas project, field work was completed between 1997 and 2000, and the results were published by the University of Nevada Press in 2007.
