Birds of Connecticut

Connecticut is small, but it has three sounds. The shoreline along Long Island Sound is terns, gulls, Ospreys and salt-marsh sparrows, with a national wildlife refuge scattered in ten pieces along 70 miles of coast. The river valleys and the suburbs in between are the everyday New England chorus. And the hills in the northwest, the Litchfield Hills, are real northern forest, where Hermit Thrushes and Veeries sing in June and Barred Owls call at night.

A yard anywhere from Greenwich to Storrs gives you the same start: Blue Jay, cardinal, robin, chickadee, titmouse, Song Sparrow, Mourning Dove, goldfinch, Downy Woodpecker and a Carolina Wren. That is ten of the album before breakfast.

The Connecticut album

These are the 100 birds people report most often in Connecticut, ranked by how frequently they turn up. The common and uncommon ones are shown; the rare and legendary cards stay face down until you catch them in the game.

Backyard birds you will hear first

The Blue Jay leads the Connecticut album, and it is the one bird everybody already knows by ear: a harsh jay, jay, a bell-like queedle, and a Red-shouldered Hawk scream good enough to fool the hawk. The Northern Cardinal whistles cheer, cheer, cheer from the top of the maple by February, and the American Robin is the first voice of the morning from March to July, a run of short, clear phrases that goes on and on.

The Black-capped Chickadee gives its name as a call and a two-note fee-bee whistle as a song, and the Tufted Titmouse rings out peter, peter, peter from the oaks. The Song Sparrow sings from the top of the hedge, two or three clear notes and then a jumble, and the American Goldfinch flies over calling po-ta-to-chip.

Add the Downy Woodpecker's whinny, the White-breasted Nuthatch's nasal yank, the Carolina Wren shouting teakettle from the woodpile, and the Gray Catbird mewing from the forsythia from May on.

The regions, by ear

The shoreline

Long Island Sound, salt marsh and barrier beach. The Stewart B. McKinney National Wildlife Refuge runs in ten units along 70 miles of coast, and its Falkner Island holds more than 2,000 pairs of Common Terns and some 40 pairs of endangered Roseate Terns, so the sound of a summer boat trip is terns screaming. Ospreys whistle from platform nests in every marsh, Piping Plovers pipe from the beaches, and in fall Bluff Point in Groton and Lighthouse Point in New Haven collect migrating songbirds and hawks heading down the Atlantic Flyway.

The Connecticut River valley and the suburbs

Marsh and farmland with towns between. Red-winged Blackbirds sing konk-la-ree from the cattails in March, Wood Ducks whistle off the ponds, and the suburban chorus of jay, cardinal, robin and titmouse fills the rest.

The Litchfield Hills and the Quiet Corner

Northern hardwood forest, hemlock ravines, hayfields and old stone walls. In June the Wood Thrush and the Veery sing at dusk, the Scarlet Tanager rasps from the canopy, Black-throated Green Warblers buzz from the hemlocks, and the Barred Owl asks who cooks for you after dark. Audubon centers at Sharon and Southbury sit in this country.

Best months to listen

May is the month. The residents are on territory, the thrushes and warblers arrive, and by the end of it every wood in the state is singing from 5 am. June keeps most of it, especially in the hills. July fades, and August is quiet but for catbirds and goldfinches.

September and October bring the fall flight along the coast, hawks on northwest winds and sparrows in the thickets. Winter is chickadees, titmice, cardinals, jays and the robins that never left, plus sea ducks and gulls on the Sound.

Places worth the drive

• Hammonasset Beach State Park, Madison: the largest shoreline park in the state, two miles of beach, and Meigs Point for shorebirds and fall migrants.
• Milford Point, Milford: a Connecticut Audubon center on the salt marsh, with terns and plovers in summer.
• Bluff Point State Park, Groton: an undeveloped coastal peninsula with more than 200 species recorded, best on a September morning.
• Lighthouse Point Park, New Haven: the fall hawk watch on the Atlantic Flyway.
• The Litchfield Hills: thrushes, tanagers and warblers in June, and Barred Owls after dark.

None of them is required. A yard with a feeder and a few oaks will give you 30 of the 100 in a year.
