History:

Saw Mill River Audubon Society sanctuaries are open year-round from dawn until dusk for members and the general public for study and enjoyment. Guided group tours of the sanctuaries are available upon request. Trail maps are available for the six sanctuaries with trails and bird lists and nature trail booklets are available for Brinton Brook and Pruyn Sanctuaries.

Pruyn Sanctuary was first established by Agnes K. And Dr. F. Morgan Pruyn, long-time residents of Chappaqua, in 1966 through a gift of 16 acres to Saw Mill River Audubon Society. Small parcels of two and four acres each were added by the Benedict and Allison families respectively from their nearby properties.

In 1978, Dr. Pruyn purchased 31 acres of the valley saving it from development and donated them to the Society as well. Agnes K. Pruyn passed away in April 1975. Dr. F. Morgan Pruyn continued to maintain and improve their land adjoining the sanctuary and took an active role in supporting the Society until his death in May 1988.

The Pruyns willed to the Society the remaining acreage of their property along Millwood Road (Route 133) and their residence that now houses the office of the Saw Mill River Audubon Society. Pruyn Sanctuary, originally Gedney Brook Sanctuary, was renamed in honor of the Pruyns in April 1990.

An additional 14 acres, the Crystal Spring parcel, was added to the sanctuary in 1997 and a donation from Alok Aggarwal, a local developer. Nestle was a previous owner of this property during the 60s when spring water was piped and bottled from this area.
