They are known for their distinctive quacking sound that echoes through the air when they’re in groups.

Connecticut’s diverse habitats provide excellent feeding grounds for these birds. They feed on aquatic plants, insects, fish, crustaceans, and mollusks. These ducks come in many colours and sizes, ranging from the small Bufflehead to the larger Mallard duck.

Apart from being an attraction to bird watchers and photographers who take pleasure in capturing photos of them amidst beautiful scenery or while feeding along river banks, Connecticut Ducks also hold cultural significance to some communities.

20 Species of Ducks in Connecticut

There are different species of ducks in Connecticut. But we see the top 20 species of ducks in Connecticut:


Ducks in Connecticut

Mallard ducks are a common sight in Connecticut. These beautiful birds are known for their vibrant green heads, brown bodies and white neck rings. They can be found in various waterways across the state, from small ponds to large lakes and rivers.

During the breeding season, male mallards display elaborate courtships to attract females. They stretch their necks and flap their wings while emitting a low quack. Once a female is interested, she will follow the male around as he swims in circles around her. After mating, the female will build her nest on land near water sources such as marshes or streams.

While these ducks are not endangered, they face habitat loss and pollution threats. Efforts have been made to protect these birds through conservation efforts such as wetland restoration and anti-pollution measures.


• Scientific Name: AnasPlatyrhynchos
• Length: 20–26 in
• Weight:1.5–3.5 lb
• Wingspan: 32–39 in

Blue-Winged Teal:

Ducks in Connecticut

Blue-Winged Teal Ducks are among the smallest ducks in North America, measuring just 14 inches from beak to tail. They are common across Connecticut during migration periods and sometimes remain to breed. These ducks can be easily identified by their striking blue colouration on the wings, which gives them their name.

These birds prefer shallow wetlands and marshes, where they can feed on aquatic plants, seeds, and insects. During breeding, males attract females with a distinctive whistling call while displaying blue feathers. Blue-Winged Teal Ducks usually lay between 7-9 eggs in a well-hidden nest close to water sources.

Despite being common in Connecticut during migration periods and breeding seasons, Blue-Winged Teal Ducks face threats such as habitat loss due to human activity and climate change affecting their food sources.


• Scientific Name: Spatula discors
• Length: 16 in
• Weight: 13 oz
• Wingspan:23 in

Green-Winged Teal:

Ducks in Connecticut

Green-winged Teal ducks are common in Connecticut during the fall migration season. These small, elegant birds are known for their brightly coloured plumage and distinctive whistling calls. They can be found in ponds, lakes, and marshes across the state from September to November.

During the breeding season, these ducks nest in wetlands across North America, including Alaska and Canada. However, as winter approaches, they migrate southward towards warmer climates. Many of these ducks stop in Connecticut to rest and refuel before continuing their journey.

Connecticut’s extensive network of wetlands provides an ideal habitat for Green-winged Teal ducks during their migration period. These waterways offer the perfect combination of food sources and shelter for these birds to survive while travelling long distances.


• Scientific Name: AnasCarolinensis

Northern Pintail:

Ducks in Connecticut

Northern Pintail Ducks, known for their elegant and striking plumage, are common in Connecticut during winter. These migratory birds travel from as far north as Alaska to spend the colder seasons here in Connecticut. The state’s coastal habitats provide ideal conditions for these ducks to thrive and make their homes.

These ducks can be easily identified by their long necks, slender bodies, and distinctive tails that taper to a fine point. Males have attractive plumage with slate grey heads and chests, white bellies, and chocolate brown feathers on their backs. Females have more subdued colouring with mottled brown feathers that help them blend into their surroundings.

Northern Pintails are considered one of the most graceful species of waterfowl due to their slender frame and swift flight pattern.

In Connecticut, they are often seen along the coast or in larger bodies of water, such as lakes or reservoirs, during the fall migration period. They are also known to breed in certain areas of the state, particularly in marshes and other wetland environments.

One interesting fact about ruddy ducks is that they are considered one of the most sexually dimorphic species of waterfowl, meaning males and females look very different.
