National Audubon Society

The mission of the National Audubon Society is to conserve and restore natural ecosystems, focusing on birds, other wildlife, and their habitats for the benefit of humanity and the Earth's biological diversity. Our national network of community-based nature centers and chapters, scientific and educational programs, and advocacy on behalf of areas sustaining important bird populations engage millions of people of all ages and backgrounds in positive conservation experiences. Audubon is making progress protecting habitat on-the-ground, while its public policy office in Washington, D.C. connects Audubon with Congress, the executive branch, courts, and mass media to ensure our great natural heritage endures for generations.
