Living or visiting Connecticut and wondering what bird you’re looking at? This article covers the most common birds of Connecticut. Odds are high the bird you’re looking at is one of them. It will also inform you on how to identify them.
Connecticut is a wonderful state for birding, especially for the multitude of shorebirds on Long Island Sound and the coastline. Birders should consider that the shore becomes crowded during the summer, making spring and fall a better bird-sighting option. Although Connecticut is the third smallest state in the U.S., it has 430 species of birds.
Litchfield’s White Memorial Conservation Center has 4,000 acres of birding habitats that include forests, marshlands, and river edges. Birders can explore the 40 miles of trails or canoe down the Bantam River for sightings. They will find, among other species, Broad-wing Hawk, Willow Flycatcher, Yellow-throated Vireo, Scarlet Tanager, and the Pileated Woodpecker.
Bantam Lake is a haven for waterfowls, including the migrating Least Bittern, American Bittern, and Common Gallinule. Osprey and the Bald Eagle are a non-infrequent sight.
The Audubon Center in Greenwich is in a 285-acre sanctuary with seven miles of birding trails. The trails wind through deciduous forests, swamps, a river, and a lake. Birders are likely to spot a Ruffed Grouse, Great Crested Flycatcher, Tree Swallow, Ovenbird, several Warblers, and the beautiful Baltimore Oriole. Birders can contact the Center regarding their fall hawk watch – over 20,000 raptors have been spotted during certain years.
Sherwood Island State Park is a large coastal park with woodland and beaches, a great place to see waterfowls such as the Glossy IBIS, Long-tailed Duck, and the Least Bittern in the spring.
Milford Point, close to the town of Milford, has been officially named an “Important Bird Area” for its abundance of shorebirds and waterfowl. The Point conveniently has an observation platform and a tower.
Lighthouse Point Park near New Haven has 15,000 raptors migrating from September to November, making this the most famous hawk watch in New England. Some of the raptors are the Turkey Vulture, Red-shouldered Hawk, and the Peregrine Falcon, among many others, possibly even a Golden Eagle. The park itself has several programs about bird migration.
