Christman Bird and Wildlife Sanctuary is a national historic district located near Delanson, Schenectady County, New York. The district includes six contributing buildings and one contributing structure on a largely wooded, rural tract. It lies in the valley of the Bozenkill and includes a waterfall along the Helderberg Escarpment. Located on the property is a two-story frame dwelling built in 1868, a stone dairy house, barns, large stone walls, and an open lean-to built by the Mohawk Valley Hiking Club. The sanctuary had its beginnings in 1888 when property owner W.W. Christman (1865-1937) and his wife, the former Catherine Bradt, began a winter bird feeding program during the great blizzard of that year.
