Site Description: The Wheeler Marsh Wildlife Management Area is a ~615-acre Spartina alterniflora -dominated low marsh at the mouth of the Housatonic River. The area receives substantial use by waterfowl hunters and some use by rail hunters. Milford Point is an 8.5-acre barrier beach with two large state-owned sandbars that are generally not covered by mean high water. The smaller of the two is often covered by storm or spring tides and the larger sandbar has recently become contiguous with the mainland. The Connecticut Audubon Society has a nature education center located on the barrier beach, which is operated under a lease agreement with the State of Connecticut, and the Stewart B. McKinney National Wildlife Refuge owns the 8.5-acre point proper. The area has much potential for education and research, and has been the site of Manomet International Shorebird Surveys since 1998, and location of an ongoing migrant banding station.

IBA Criteria: Connecticut (and Federally) Threatened species; High Conservation Priority Species; Rare, Unique or Representative Habitat; 500+ Waterfowl (winter) 1000+ Waterfowl (staging); 100+ Terns; 500+ Shorebirds; 100+ Individual Staging/Feeding Wading Birds; Exceptional Concentrations of Migratory Landbirds; Single Species Concentrations; Long-term Research and/or Monitoring. 

Birds: The marsh, sandbars, and barrier beach are some of the most important shorebird migratory stopover areas on Long Island Sound, providing foraging areas and resting areas for tens of thousands of shorebirds each year. Numbers of some species of migrating shorebirds (especially Semipalmated and Black-bellied Plovers) may elevate this area to the level of national or continental significance. The marsh, barrier beach and sandbars provide nesting habitat for several species of regional and national concern. Two to ten pairs of Piping Plovers nest in area annually. Common and Least Terns have nested in the area with up to 100 pairs of each species in recent years; it is an important tern staging area, including some Roseate Terns, with 1000+ terns recorded annually. Seaside and Salt Marsh Sharp-tailed Sparrows nest in the marsh. The marsh may also be a significant migratory stopover area for Saltmarsh and 'Acadian' Nelson's Sharp-tailed Sparrows. The area is an American Oystercatcher nesting area for 2-3 pairs. Species among 10-20,000 shorebirds recorded annually include small numbers of Red Knot, and significant (1000+/year) numbers of Black-bellied and Semipalmated Plovers. The marsh is a regionally important Clapper Rail and Willet nesting area. The marsh serves as an important waterfowl stopover and staging area, and a nesting area for American Black Duck and Gadwall. It is also one of Connecticut's most significant feeding areas for egrets and herons, and is particularly important to Black-crowned Night-Herons, which, however, can cause problems for other nesting bird species. The area is a Peregrine Falcon foraging area in migration/nesting season, Horned Lark nesting area, important heron/egret foraging area in nesting/post-nesting dispersal seasons, regionally important stopover/wintering area for Short-eared Owl, Northern Harrier, and American Bittern, Osprey nesting area, and significant migratory stopover. Barrier beach is one of Connecticut's primary 'Ipswich' Sparrow wintering and migratory stopover habitats. Milford Point is one of Connecticut's most-visited bird viewing areas. 

Non-avian Resources: Wheeler Marsh and Milford Point are one of the healthiest remaining tidal marsh/barrier beach systems in Connecticut, and as such host several uncommon plant species. The area is popular for fishing and hunting, and the marsh is an important nursery for many species of fishes. There is a significant Diamondback Terrapin population. A significant number of Red Bats (Special Concern) are known to use the area during fall migration.

Existing Conservation Measures: Access to the USFWS property is limited to protect wildlife in the nesting season. The CT DEP Wildlife Division, USFWS and Connecticut Audubon Society use interns and volunteers to monitor nesting Piping Plovers and Least Terns.
