Connecticut Birds and Birding in Connecticut State

eBird lists over 445 types of birds as occurring in the state of Connecticut.

The most common bird in Connecticut: the most frequently seen bird in the state is the Blue Jay. It is reported on 43% of bird watching lists.

If you are serious about knowing the birds native to Connecticut, then check out eBird for Connecticut. It has recent sightings and photos, illustrated checklists with weekly abundance bar charts for state, counties, and individual hotspots of the best birding locations.

If you want to know about other people interested in birds in your area, join a local bird group. The American Birding Association maintains a list of bird watching clubs for each state.

Connecticut Bird Identification

This section is the species accounts. These are designed to help you to recognize birds you see in your backyard. I have used eBird to select the birds that are most common. “Common” means the birds seen most often throughout the year, not necessarily the most numerous.

Each species account starts with a photograph. In the identification section I am using size and shape and bill type before considering the color or patterns on the birds. I find these more reliable when trying to identify an unknown bird. Pay attention to body and tail shape and especially bill shape of birds you see, not just plumage color.

In the section on bird feeders and foods I tell how to attract each species. Not all types of backyard birds will come to feeders. But all backyard birds can be attracted with water. So don’t forget to add a birdbath to your bird feeding station.

To appear in this article, most birds are widely distributed throughout the state and are often year-round residents. However, for those birds that are more localized in place or time, I list the general region and seasonality. Please see the section following these species accounts for the lists of common species by season.

Even if a species is found in a general area, they occur only in the habitat they prefer. So, the exact habitat of your neighborhood is important for the presence of absence of certain kinds of birds.

1. Blue Jay (Cyanocitta cristata)

A common and well-known bird in the eastern half of the United States.

Blue Jay. skeeze from Pixabay

Range in Connecticut: Blue Jays are year-round residents throughout Connecticut.

Identification: 

Size: About that of American Robin. 

Shape: Fluffy, large crested head, ample tail. Large strong legs. 

Bill: Black, long and stout. 

Color: Blue above, white below. Black neck collar. White patches in wing.

Habitat, range & behavior: Woodlands and towns.

Found in the eastern half of the United States. In summer into southern Canada. 

Bold and brash. May bully smaller birds. Jays gulp lots of seeds or other food at once, storing it in their crop. Then they fly off and bury food items in a hidden cache.

Food and feeder preference: Omnivorous. They can quickly empty your feeder! 

Because they are also aggressive toward other feeder birds, some people put mesh cages around smaller bird feeders. Small birds can go through, squirrels and larger “pest” birds are prevented entry. Some people feed jays peanuts, perhaps away from the seed feeders.

2. Northern Cardinal (Cardinalis cardinalis)

This is one of the most common and popular backyard birds in the eastern half of the United States.

Northern Cardinal. GeorgeB2 from Pixaby

Range in Connecticut: Northern Cardinals are year-round residents throughout Connecticut.

Identification: 

Size: Cardinals are a bit smaller than American Robins, about the same size as Red-winged Blackbirds. 

Shape: Plump body with fairly long full tail. Wispy crest. 

Bill: Short, heavy, conical, pink. 

Color: That bright red color is matched by few other birds. Black face. The female is grayer, but with hints of red in wings and tail, and has a crest, too.

Habitat, range & behavior: Cardinals are year-round residents in shrubby woodland edges.

Found from the eastern United States to Texas and Arizona south into Mexico. 

That large conical bill is made for chewing seeds. Watch them crack open sunflower seeds, spit out the hulls, and pluck the kernel with their tongues!

Food and feeder preference: Black oil sunflower seeds. Many types of seeds, berries, nuts in larger hopper or tray feeders.

In typical woodpecker fashion, it hitches up the tree trunk and larger branches.

Food and feeder preference: This species eats insects and nuts. They may eat peanuts from a tray feeder and eat from a suet block.

14. Red-winged Blackbird (Agelaius phoeniceus)

These noisy flocking birds are most often found in marshes. But in winter they are found in backyards.

15. European Starling (Sturnus vulgaris)

Introduced to North America in the late 1800’s, they crossed the continent, often to the detriment of native cavity-nesting birds. The prime example of an invasive species.

European Starling. Greg Gillson

Range in Connecticut: European Starlings are year-round residents throughout Connecticut.

Identification: This is a key species for comparing with an unknown bird. 

Size: 8-1/2 inches from bill tip to tail tip. About the size of a Red-winged Blackbird. Smaller than an American Robin. Larger than a White-crowned Sparrow or Spotted/Eastern towhee. 

Shape: Stocky with large head, short square-ended tail. Longer legs. 

Bill: As long as head. Sharp pointed. Yellow in spring, otherwise dark. 

Color: They are grayish brown much of the year, with glossy iridescence and white spotting during the spring.

Habitat, range & behavior: Lowland birds that need trees large enough for nest cavities but plenty of open area for feeding. They are most abundant in urban and suburban areas where they find food and artificial nest cavities. 

Resident from coast-to-coast from southern Canada to northern Mexico. In summer north across Canada and Alaska. Native range is Europe to Pakistan, north Africa. 

Often viewed as a pest, starlings often bully other backyard birds, taking over bird feeders, and stealing nest cavities from smaller native birds. In winter they can form into flocks of tens of thousands.

Food and feeder preference: Primarily insects when available, often feeding on the ground. Discourage them from your backyard hopper and tray feeders by never feeding birds table scraps (including bread or meat). They have weak feet and do not perch well on tube feeders. A cage mesh around smaller hopper feeders may keep them out.

16. Common Grackle (Quiscalus quiscula)

Sometimes considered a pest to crops, grackles are longer and lankier than very similar blackbirds.

Common Grackle. GeorgiaLens from Pixabay

Resident in the southeastern United States. In summer they migrate northward and west to the central United States and Canada. 

They monopolize feeders and are bullies toward other birds.

Food and feeder preference: Grain, corn, acorns, small aquatic fish and amphibians. To discourage them, use tube feeders, rather than hopper or tray feeders. Don’t over-feed, keep spilled seed picked up.

17. House Finch (Haemorhous mexicanus)

Originally a bird of the West, now found across most of the US. There are other red finches, but these are the ones most likely in residential areas.

Food and feeder preference: Feed mostly on insects and spiders. They will feed on suet.

22. Northern Flicker (Colaptes auratus)

Of all the bird identification questions I get asked, this common larger backyard bird is the bird most people ask about. It doesn’t occur to those unfamiliar with it that this could be a woodpecker.

Northern Flicker. Greg Gillson.

Range in Connecticut: Northern Flickers are year-round residents throughout Connecticut.

Identification: 

Size: About the size of a Mourning Dove. Larger than a robin. 

Shape: Stocky with short legs, short tail, big head.

Color: Back is brown with black bars. Under parts pinkish with black spots. Undersides of black wing and tail feathers are bright salmon red (West) or yellow (East). Head gray (West) or brown (East) and males with red (West) or black (East) whisker marks and nape marks (East). Black crescent across chest. White rump seen in flight.

Habitat, range & behavior: Found in woodland edges and forests. 

Year-round resident from extreme southern Canada, across all of the lower-48 states and in the mountains of Mexico and Middle America. In summer breeds northward well into Canada and Alaska. 

Frequently noted hopping on ground pecking in the ground for insects. In late spring, males proclaim their territory by rapid pounding on a hollow tree branch, though the ringing of metal downspouts at dawn is louder and carries much farther, to the exasperation of anyone trying to sleep inside!

Food and feeder preference: Ants and beetles are their primary foods. Will eat black oil sunflower seeds and are attracted to suet.

23. Chimney Swift (Chaetura pelagica)

Swifts have such small weak feet that they cannot perch on wires or trees like swallows. Look for them high in the air chasing bugs with rapid wingbeats. 

Chimney Swift. Jim McCulloch CC 2.0

Range in Connecticut: Chimney Swifts are summer residents throughout Connecticut.

Identification:

Size: Small bird. Smaller than House Finches or Cliff Swallows.

Shape: Small head on short neck, very short tail. Thin pointed wings with no apparent bend at the wrist as most other birds.

Color: Gray-brown throughout.

Habitat, range & behavior: Open sky, above forests or residential areas.

They are summer residents east of the Rockies from southern Canada southward. They do not winter in the United States.

In fall migration they form large flocks of hundreds or thousands and swirl into large chimneys at dusk. Because the upper arm is so short as to barely exist, the flight of swifts is described as rapid and twinkly, not smooth and graceful as swallows.

Food and feeder preference: Insects caught on the wing. Will not visit feeders.

24. Northern Mockingbird (Mimus polyglotos)

This bird sings from exposed perches most of the year and often through the night. They have an unending supply of their own unique short phrases that they repeat about 3 times each, but frequently intersperse songs of other birds.

They are found in eastern and southern parts of the US, West Indies, and south into Mexico.

They boldly defend their nests from other birds, cats, and intruders.

Food and feeder preference: Northern Mockingbirds eat insects, berries, and fruit. You may attract mockingbirds to your feeder with grapes, raisins, apple slices. They will come to a suet block. They readily use a bird bath.

25. Chipping Sparrow (Spizella passerina)

As with many vireos, they sing persistently through the summer and through the heat of the day, not just primarily during spring and at dawn as many other songbirds.

Food and feeder preference: They eat insects and will not come to feeders.

28. Cedar Waxwing (Bombycilla cedrorum)

Waxy red tips to the wing feathers give these birds their unique name. Maybe it’s the fancy crest. Maybe it’s the bandit mask. Maybe it’s the yellow band at the tip of its tail. But these are one of my favorite birds.

Brown-headed Cowbird. Greg Gillson.

Range in Connecticut: Brown-headed Cowbirds are year-round residents throughout Connecticut.

Identification:

In summer they breed across Canada and most of the United States and Mexico. In winter they move south out of Canada and occupy both coasts and southeastern States in the US.

These small blackbirds join other flocks of blackbirds in cattle feedlots. You may see cowbirds riding on the backs of cattle, sheep, or horses. They originally rode on the backs of American bison on the Great Plains but expanded when forests were cut.

Food and feeder preference: Cowbirds eat grains, seeds, and insects. They will readily come to hopper and platform feeders. They are larger and more aggressive, so keep other birds from feeders and have a big appetite!

Common Birds in Connecticut

To determine how common each species is I used the data from actual bird sightings from the citizen science program eBird. Birds are listed by frequency. That is, how often the species is recorded on checklists submitted to eBird (a percentage).

When choosing the birds to include in this article I leaned strongly to birds that are present throughout the year in good numbers. Thus, many of the common birds are year-round residents. This means that they live in the same location all year. They raise their young in your neighborhood. They don’t migrate. Or if the species does migrate, the ones living in your area don’t. If this is the case, some migrants may move into your area during certain times of year, adding to the same species that are in your yard full time.

Some migrant birds visit your yard during the “summer.” Often, they arrive in spring and remain until late fall. They nest and raise their young in your neighborhood. These are the summer residents.

Other migrant birds visit your backyard during the “winter.” Some of these winter visitors may arrive in July and remain into April. Others may only be found in the cold of December or January. They key here is that they nest and raise their young somewhere else. They only visit your yard in the non-breeding season.

Migration is an amazing spectacle.
There will be birds that fly through your region in spring or fall (or both). They may visit your backyard only a few days or weeks a year. They aren’t regular enough, or stay long enough, to be included in this article. But the number of briefly visiting migrant birds could double the number of species presented here. You may see them over time. Consult checklists in eBird for your county to see what is possible.

I have generally excluded common waterfowl, birds of prey, shorebirds, seabirds, and others that aren’t usually found in residential areas. But they may certainly fly over or be seen regularly if your home is on a shoreline, for instance.

Frequently Asked Questions

What birds stay in CT for winter?

Connecticut transforms into a vibrant haven for many feathered friends during the winter months, even as some migratory species head south. Here are some common birds that stick around the Constitution State to grace the frosty landscapes:

Songbirds:

Norhern Cardinal: Their striking red plumage adds a splash of color against the wintery backdrop. Both males and females sing melodic tunes throughout the cold season.

Tufted Titmouse: These bold birds with their distinctive crest add a dash of personality to winter gardens and feeders.

American Robin: These iconic birds continue foraging for berries and worms, occasionally offering cheerful bursts of song on sunny days.

Dark-eyed Junco: These shy ground feeders with their slate-gray backs and white bellies are common sights in fields and open woodlands.

Woodpeckers:

Downy Woodpecker: These small woodpeckers tap away on tree trunks, searching for insects and larvae hidden beneath the bark.

Hairy Woodpecker: Slightly larger than their Downy cousins, these woodpeckers also bring life to winter forests with their drumming calls.

What is the state bird of Connecticut?

The state bird of Connecticut is the American Robin, a beloved songbird known for its cheerful melodies and bright orange breast. These familiar birds grace the state year-round, bringing splashes of color and joyful songs to backyards, forests, and parks.

In 1943, the American Robin was adopted as the official state bird due to its widespread presence and popularity among residents. Their melodic songs, especially during spring mornings, offer a heartwarming welcome to the warmer season. Their adaptability and resilience have also earned them a respected place in Connecticut’s natural heritage.

What is the big black bird in CT?

Finding American Crows in Connecticut is quite easy, as they are incredibly adaptable and widespread throughout the state. These intelligent birds thrive in various habitats, making them a familiar sight regardless of where you are. Here are some specific places to look:

Forests and woodlands: Crows commonly forage in wooded areas, searching for insects, small animals, and berries. Look for them hopping on forest floors, perched on branches, or soaring high above the treetops.

Fields and agricultural areas: These open spaces offer abundant food sources for crows, like insects, rodents, and leftover agricultural products. Observe them scavenging in fields, perched on fence posts, or even gathering in large flocks on the ground.

Urban and suburban areas: Crows have successfully adapted to living alongside humans. They frequent parks, backyards, and even busy city streets, scavenging for food scraps and nesting in tall trees. Keep an eye out for them rummaging through garbage bins, perched on rooftops, or flying overhead in their signature “caw” calls.

Coastal areas: Crows often visit beaches and marshes, searching for shellfish, small fish, and other coastal creatures. Watch for them scavenging along the shoreline, perched on rocks or pilings, or even dipping their beaks into the water.
