List of birds of Connecticut facts for kids

This is a list of all the different types of birds that have been seen in the state of Connecticut. This list is based on the official checklist from the Avian Records Committee of Connecticut (ARCC), updated on March 14, 2022. Most bird watchers in Connecticut use this list to keep track of the birds they spot.
This list includes all known bird species in Connecticut. It features birds that live here all the time, those that visit during migration or winter, and even very rare visitors. It also includes birds that are now extinct (gone forever) or extirpated (no longer found in Connecticut, but still exist elsewhere). About 280 bird species are seen regularly in Connecticut every year. In the past, surveys showed around 150 to 173 species were confirmed to breed in the state.
Out of 451 species on this list, 307 are common residents or regular migrants. Nine species were introduced to North America by humans. Three species are now extinct, and four no longer live in Connecticut (though two of these are still brought in for hunting). Another 139 species are considered rare or accidental visitors. Twelve species are included based only on a single sighting.
Here are some special tags used for certain species:
- (R) Rare or accidental - These birds are not seen often and need special proof if you spot them.
- (I) Introduced - These birds were brought to North America by people.
- (X) Extinct - This species no longer exists anywhere in the world.
- (E) Extirpated - This species no longer lives in Connecticut, but you can find it in other places.
- (S) Sight record only - This bird has only been seen once or a few times, without other proof like photos.

Loons
Order: Gaviiformes Family: Gaviidae
Loons are aquatic birds, about the size of a large duck, but not related to them. Their feathers are mostly gray or black, and they have spear-shaped bills. Loons swim and fly well, but they are very clumsy on land because their legs are placed far back on their bodies. Three species have been seen in Connecticut.
- Red-throated loon, Gavia stellata — This bird is quite common, especially along the coast and at river mouths during spring and fall migration. It's less common in winter, mostly found in eastern Long Island Sound. Groups of 100-200 can gather in November.
- Pacific loon, Gavia pacifica (R)
- Common loon, Gavia immer — Historically, this bird rarely nested in Connecticut, and no recent nesting has been seen. It's quite common during spring and fall migration, found in coastal waters, large lakes, and reservoirs. Pollution and changes in water levels have affected their numbers.
Southern Storm-Petrels
Order: Procellariiformes Family: Oceanitidae
Storm-petrels are the smallest seabirds, related to petrels. They feed on tiny ocean creatures and small fish from the water's surface, often while hovering. Their flight is fluttering, sometimes like a bat. Two species have been seen in Connecticut.
- Wilson's storm-petrel, Oceanites oceanicus — This bird is regularly seen in eastern Long Island Sound during the summer, but it's uncommon further west.
- White-faced storm-petrel, Pelagodroma marina (R)
Northern Storm-Petrels
Order: Procellariiformes Family: Hydrobatidae
These storm-petrels are similar to the southern storm-petrels in looks and habits. However, genetic differences mean they are placed in a separate family. Two species have been seen in Connecticut.
- Leach's storm-petrel, Hydrobates leucorhous (R)
- Band-rumped storm-petrel, Hydrobates castro (R) (S)
Shearwaters and Petrels

Storks
Order: Ciconiiformes Family: Ciconiidae
Storks are large, heavy, long-legged, and long-necked wading birds with strong, long bills and wide wings. They do not have the special "powder down" feathers that other wading birds use to clean off fish slime. Storks also cannot make sounds because they lack a voice box. One species has been seen in Connecticut.
- Wood stork, Mycteria americana (R)
Frigatebirds
Order: Suliformes Family: Fregatidae
Frigatebirds are large seabirds usually found over tropical oceans. They are black, or black and white, with long wings and deeply forked tails. Males have colorful throat pouches that can inflate.

- Double-crested cormorant, Nannopterum auritum — This bird is now common from spring to fall. Around 1900, it was a rare visitor. It's much less common in winter, but sightings are increasing. They are mostly found on coastal islands, major rivers, and some inland lakes. By the late 1990s, there were at least 1,000 nesting pairs in the state.
Pelicans
Order: Pelecaniformes Family: Pelecanidae
Pelicans are very large water birds with a unique pouch under their beak. Like other birds in their group, they have four webbed toes. Two species have been seen in Connecticut.
- American white pelican, Pelecanus erythrorhynchos
- Brown pelican, Pelecanus occidentalis (R)
Herons, Egrets, and Bitterns
Order: Pelecaniformes Family: Ardeidae
This family includes herons, egrets, and bitterns. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to have shorter necks and are more secretive. Birds in this family fly with their necks pulled back, unlike other long-necked birds like storks. In the past, egrets were hunted for their feathers, but their numbers recovered once they were protected. Twelve species have been seen in Connecticut.
- American bittern, Botaurus lentiginosus — This bird is uncommon but found throughout the state at any time of year. It lives mostly in large marshes. Its numbers likely dropped when common reeds took over cattail marshes.
- Least bittern, Ixobrychus exilis — This bird is rarely seen. It's found from spring through fall in large marshes, preferring areas with a mix of plants and open water.
- Great blue heron, Ardea herodias — This bird is common in marshes and other water bodies from spring through fall. Its numbers have been growing recently. It's increasingly seen in winter, but still uncommon then.
- Great egret, Ardea alba — This bird is quite common along the coast from spring through fall and rarely in early winter. It's less common inland. Groups of about 100 pairs nest on islands like Great Captain Island, Charles Island, and Dyuck Island. Their numbers have been increasing.
- Little egret, Egretta garzetta (R)
- Snowy egret, Egretta thula — This bird is quite common along the coast from spring through fall. It can be found resting at night with great egrets and cormorants. It nests in woody areas on coastal islands. The population in Long Island Sound (including New York) slightly decreased from 1,650 pairs in 1977 to 1,390 in 1998.
- Little blue heron, Egretta caerulea — This bird is not common, seen from spring through early fall, most often in mid-to-late summer when young birds arrive from the south. It nests in woody areas of coastal islands. Its nesting range expanded north along the East Coast in the 20th century.
- Tricolored heron, Egretta tricolor — This bird is seldom found in the state. It's seen in coastal waters in spring and summer and has occasionally nested in the Norwalk Islands. In the mid-20th century, it became more common in New York and southern New England.
- Cattle egret, Bubulcus ibis — This bird is rarely seen, found in coastal waters in spring and summer. It has regularly nested in the Norwalk Islands. This bird is originally from the Old World and arrived in South America in the 1880s, spreading north to Florida by the 1940s and then along the East Coast.
- Green heron, Butorides virescens — This bird is quite common, found in marshes and swamps from spring through fall. Loss and damage to marshes likely caused a decline in its population in the 20th century.
- Black-crowned night-heron, Nycticorax nycticorax — This bird is quite common on the coast and on the Connecticut river from spring through fall. It's rarely found in winter. It spreads inland along the Connecticut and Housatonic Rivers in late summer. It nests on coastal islands. The state population was about 500 pairs as of 2004. Numbers declined in the Northeast in the 20th century, possibly due to human activity and pesticides.
- Yellow-crowned night-heron, Nyctanassa violacea — This bird is rarely seen, found in coastal marshes from spring through early fall, usually in the western part of the state.
Ibises and Spoonbills
Order: Pelecaniformes Family: Threskiornithidae
This family includes ibises and spoonbills. They have long, wide wings and long bodies and necks, with rather long legs. Their bill is also long; it's curved downward for ibises and straight and flattened for spoonbills. Four species have been seen in Connecticut.
- White ibis, Eudocimus albus (R)
- Glossy ibis, Plegadis falcinellus
- White-faced ibis, Plegadis chihi
- Roseate spoonbill, Platalea ajaja (R)
New World Vultures
Order: Cathartiformes Family: Cathartidae
New World vultures are not closely related to Old World vultures, but they look similar because they evolved in similar ways. Like Old World vultures, they eat dead animals. However, unlike Old World vultures, which find food by sight, New World vultures have a good sense of smell to find carcasses. Two species have been seen in Connecticut.
- Black vulture, Coragyps atratus
- Turkey vulture, Cathartes aura
Osprey
Order: Accipitriformes Family: Pandionidae
The osprey is a medium-large bird of prey that eats fish. It lives in many different places because it can nest near any body of water that has enough food. It is the only member of its family.
- Osprey, Pandion haliaetus — These unique black and white birds are common in Connecticut from spring through fall. They are often seen on nesting platforms along the east and central coastline. They are also called "fish hawks."
- Their busiest migration times are early to mid-spring (around St. Patrick's Day) and late summer through early fall (around Labor Day). Young birds migrate a bit later.
- Ospreys eat medium-sized fish, like flounders, which they catch by diving feet first from the air. They are unique in Connecticut for having a fish-only diet and are one of the few raptors that hunt live fish. You might see them hovering over the water before splashing down, sometimes going 2 or 3 feet deep! They can catch up to 10 fish a day. Adult ospreys feed their young for up to 8 weeks. They have even been known to snatch goldfish from backyard ponds.
- This bird used to be rare, partly because of pesticide pollution (like DDT). In 1974, there were only nine nests in the state, but by 1999, there were 162 nests with 315 young birds. Their range has expanded westward along the coast and up the Connecticut and Quinnipiac rivers. Their nests stay strong through the winter, while the birds migrate as far as South America. Ospreys usually build nests in the highest possible places, including cell phone towers.
- In May 2008, the Maritime Aquarium at Norwalk set up a webcam to watch an osprey nest on Manressa Island, near a power plant. The aquarium watches ospreys because they are "at the top of the food chain" and "an important indicator of the health of the entire ecosystem."
Hawks, Eagles, and Kites
Order: Accipitriformes Family: Accipitridae
This family of birds of prey includes hawks, eagles, kites, and harriers. These birds have very large, powerful, hooked beaks for tearing meat from their prey. They also have strong legs, powerful talons (claws), and excellent eyesight. Fifteen species have been seen in Connecticut.
- White-tailed kite, Elanus leucurus (R)
- Swallow-tailed kite, Elanoides forficatus
