About the Constitution Marsh Audubon Center and Sanctuary

Constitution Marsh Audubon Center and Sanctuary, owned by New York State Parks and managed by Audubon New York,  is a unique and beautiful tidal marsh located in Putnam County, New York, and serves as vital natural habitat in the Hudson River Estuary. It is situated on the east shore of the Hudson River, just south of the village of Cold Spring. The marsh is an Audubon New York Important Bird Area, a New York State Bird Conservation Area, and is designated as a Significant Coastal Fish and Wildlife Habitat.

Constitution Marsh Audubon Center and Sanctuary serves as the hub of our four Hudson River Audubon Sanctuaries. We conduct conservation education programs for public and private groups, participate in regional and hemispheric bird studies, and take an active part in regional invasive species management and habitat restoration efforts.
