Over 500 acres in size, Buttercup is an area of diverse habitats with rolling, open grasslands, second growth and more mature woodlands, a former orchard and a marshy, flooded woodland. There are six miles of trails throughout the sanctuary. Over 80 species of birds are possible on a good May day. Of special interest are nesting Great Blue Herons, Wood Ducks, Bobolinks and other birds of the field. Both Golden-winged and Lawrence’s Warblers are seen periodically. The sanctuary is relatively undeveloped. Open from dawn until dusk, seven days per week.
