The National Audubon Society (Audubon) is a non-profit environmental organization dedicated to conservation. Located in the United States and incorporated in 1905, Audubon is one of the oldest of such organizations in the world and uses science, education and grassroots advocacy to advance its conservation mission. It is named in honor of John James Audubon, a Franco-American ornithologist and naturalist who painted, cataloged, and described the birds of North America in his famous book Birds of America published in sections between 1827 and 1838.
