State of Connecticut

Birding Connecticut

For the third smallest state in the US, Connecticut has a wide variety of habitat, and subsequently, birds. A really dedicated and lucky birder could find up to 290 species in one year in a state that lists 406 as the total number of species. Coastal lowlands border the Long Island Sound, a large salt water estuary that is fed fresh water from large rivers such as the Connecticut, Housatonic and Thames. These coastal areas are rest stops for a great number of shorebirds as they wend their way up to their breeding grounds and down their winter homes. There are well over 250 species of regularly occurring birds that can be seen along the coast. Nesters in this group include the endangered Piping Plover, Least Tern, and, on Falkner’s Island right off the coast, Roseate Terns.

In the spring, around mid May, migration is in full swing and birds ascend upon this state with great fervour. Thirty-six species of warbler have been recorded, and 33 drop in typically, twenty-five of them staying to breed. The Northwest Hills of the state are home to a number of rarities at this time and are included in every birder’s big day. River Road in Kent, is one of the best places to catch the land birds, representing a good variety of flycatchers, thrushes, and warblers. The Northeast corner is also home to some of the more northern-driven birds.

Connecticut was largely an agricultural state up to the late 1880s. But as farming waned, many of the fields reverted to woodland. Evidence of this history is found in the countless stone walls running throughout the state’s wooded lands. Hardwood trees such as the black, red and white oaks dominate. The drumming of any one of 6 of the 7 woodpeckers that make these woods their home can be heard, occasionally joined by the pee-a-weee of the Eastern Wood Pewee, the nasal anking of White-breasted Nuthatches, and the scolding of Tufted Titmice.

Winter is the ideal time for seeing waterfowl off the coast. As the inland waters in the surrounding areas freeze, scores of ducks, loons, grebes, and geese make their way to the open sound. One of the big winter shows occurs along the southern end of the Connecticut River, where Bald Eagles, also driven Southeast by frozen water, can be found all along the shores of the waterway.

Birding is a very popular pastime in Connecticut, with at least four local bird clubs (including New Haven Bird Club, Western Connecticut Bird Club, Nachaug Ornithological Society & Hartford Audubon Society – not a branch of National Society – which is one of themost active clubs in the state, having the most field trips); and the Connecticut Ornithological Association (COA). The COA maintains the rare bird alert (203-254-3665) and publishes the quarterly The Connecticut Warbler, a journal of Connecticut ornithology. The New Haven Bird Club created and sponsors the BIG SIT!, a world-wide sedentary birding competition. There are also 14 local branches of the National Audubon society, a number of nature centres, and the Connecticut Audubon Society.

Since its beginning, the Society has remained active in the local birding community, providing a venue for both novice and expert birders. In 1975 total membership was over 100. In recent years membership has held steady at about 80. The society has upheld throughout its existence a tradition of providing local birders with lively programs during its monthly meetings, numerous field trips to birding hot spots both local and distant, and opportunities to participate in censusing and research efforts through such activities as the May and Christmas counts and bird banding.

  • IBA Stratford Great Meadows

    WebpageSatellite View
    The Great Meadows estuarine system, located on Stratford's West Shore, East of Bridgeport Harbor, is comprised of barrier beach, ditched and unditched saltmarsh, filled wetland and upland. About sixty percent of the marsh is low marsh dominated by saltmarsh cordgrass, and forty percent is high marsh with saltmeadow cordgrass. The area also has several small fresh or brackish ponds, salt pannes and tidal mud and sand flats. The area contains the largest block of unditched saltmarsh (about 225 acres) left in Connecticut. Great Meadows Marsh is a significant over-wintering area for waterfowl, especially Black Ducks. The rare Snowy Owl, threatened Short-eared Owl, and special concern Ipswich Sparrow, can also be found wintering here. It is a critical nesting habitat for special concern species Saltmarsh Sharp-tailed and Seaside Sparrow, Willet, and the threatened Least Tern and Piping Plover.
  • NR Devil's Den Preserve

    WebpageSatellite View
    At 1,756 acres, Devil's Den is the Conservancy's largest preserve in Connecticut. Here, with your help, the Conservancy has protected a valuable oasis for wildlife and a natural filter for thousands of people who need clean water.

  • NR Long Wharf Nature Preserve

    PDFSatellite View
    Just off I-95 and fronting on New Haven Harbor, this preserve is the result of human disturbance and the resilience of nature. The upland, created by filling, evolved into a grassland and a small woodland dominated by tall cottonwood trees, almost all the result of natural seed dispersion. The tidal wetland and dune area accreted over the 50 years since I-95 was constructed. At low tide, the preserve encompasses approximately 15 acres, from mud flat to dune to salt marsh to upland. A loop trail connecting the shore and upland and leads to the historic Oyster Point neighborhood.

    WebpageSatellite View
    Guilford Salt Meadows Sanctuary is located in Guilford, Connecticut along the East River, a tidal river that flows into Long Island Sound. The tidal wetlands that form the heart of the Guilford Salt Meadows Sanctuary are a remnant of the great salt and brackish water marshes that once extended nearly continuously along the Atlantic Coast from Maine to Georgia. These wetlands support specialized saltmarsh vegetation and animal life. They also provide vital refueling and nesting stops for thousands of migratory birds.
  • NWR IBA Stewart B McKinney

    WebpageSatellite View
    Situated on Murdock Hill, near the mouth of the Menunketesuck River at the junction of Gatchen Creek, Salt Meadow Unit serves as the visitors center and headquarters of the Stewart B. McKinney NWR. This former estate is owned by the USFWS. It contains habitats ranging from Spartina patens-dominated high -salt meadow- marsh to mature deciduous forest with some areas of upland fields, scrub and young deciduous forest. Some of the habitat is managed to provide a variety of second growth stages for diversity of habitats. The area is one of the most important fall migratory stopover areas for Neotropical migrant landbirds in Connecticut providing important habitat for many species of migrant songbirds. At least 29 species of warblers have been recorded in fall migration.

  • SP Hammonasset Beach

    WebpageSatellite View
    Hammonasset Beach State Park was created and the first land purchased in 1919. One of the last and most important additions was the purchase of 339 acres of Meigs' Point. The park borders Long Island Sound for about 10,000 feet and the Hammonasset River for about 5000 feet. The habitat consists of approx. 600 acres of salt marsh; 300 acres of grass parking and camping areas and about 100 acres of young forest upland. The unique location of several of the upland areas within the marsh and grassland peninsula creates an effective migrant trap.
  • WMA Barn Island

    WebpageSatellite View
    Barn Island Wildlife Management Area consists of approximately 1000 acres of land in the extreme southeast corner of the state, in a protected enclave sheltered by headlands. It is the largest coastal wildlife management area in the state. The habitat is dominated by 540 acres of deciduous forest and 290 acres of tidal marshes, but there are also significant areas of open salt water, four waterfowl impoundments, and coastal scrub woodlands and thickets. The Barn Island area is popular with birders. Barn Island and the recently acquired 144-acre addition provide nesting, and/or feeding habitats for several state-listed species of birds, including Seaside and Saltmarsh Sharp-tailed Sparrows, Willet, and King Rail. Barn Island also provides feeding habitats for Great and Snowy Egrets, Glossy Ibis, and Little Blue Heron, and Common and Least Terns, and supports wintering populations of Short-eared Owl and "Ipswich" Savannah Sparrows. Saltmarsh Sharp-tailed Sparrows are listed as "near-threatened" by BirdLife International, and as such, any site that supports 10 or more pairs or 30 or more individuals of any near-threatened species would meet the criteria of a globally significant site.
  • WMA IBA Charles E Wheeler

    WebpageSatellite View
    Wheeler marsh is an ~615 acre Spartina alterniflora-dominated low salt marsh at the mouth of the Housatonic River, and is a wildlife management area managed by the State of Connecticut Department of Environmental Protection for waterfowl and marsh bird hunting and the benefit of other wildlife.
  • WMA IBA Quinnipiac

    WebpageSatellite View
    900 acres of the tidal marsh is owned by the State of Connecticut and managed by the Department of Environmental Protection as a Wildlife Management Area; 14 additional acres are owned by the Hamden Land Trust. The Quinnipiac River originates in the Deadwood Swamp on the New Britain/Farmington border, and flows 38 miles to New Haven Harbor. The tidal salt marsh is south of Sackett Point Road, North Haven, and is influenced by the daily rise and fall of the tide. The marsh serves as a significant population of nesting Osprey (10 pairs), significant wintering area for Northern Harrier (3-4 birds), and one of few known nesting locations for Common Moorhen and Least Bittern in Connecticut. The marsh is a nesting and wintering area for American Black Ducks, and a nesting area for Saltmarsh Sharp-tailed Sparrow (unknown size of population). The marsh has been a significant roosting area for mixed flocks of blackbirds in the spring and fall migrations, including Red-winged Blackbirds and Common Grackles.
