Savannah sparrows, bobolinks, and eastern meadowlarks regularly nest in the abandoned hayfields while nest boxes provide opportunities to view eastern bluebirds and other cavity-nesting species. Dense vegetation along Fairfield Brook provides an ideal nesting habitat for marsh wrens and a variety of other bird species.

Fairfield Brook Wildlife Management Area contains a variety of habitats from abandoned agricultural fields, shallow marshes with a wooded swamp, mixed woods, and a stand of hardwoods.

Parking is informal with room for 1 or 2 cars at a bar-way off East Road as well as on a cart path off of Swamp Road near March Hare Road. Driving into the field is prohibited.

The field along Swamp Road is cut annually to maintain habitat for ground-nesting bird species.
