The red-breasted merganser is a large duck with a long, slender body and dark green-black plumage. Its head and neck are reddish brown and its bill is orange with a black tip. The male has an iridescent crest that extends down its back, while the female’s crest is much smaller. Its wingspan can reach up to 30 inches.

They are excellent divers, swimming underwater in search of fish, crustaceans, amphibians, and mollusks. They mainly inhabit freshwater areas such as lakes and rivers, but they also occur in coastal waters during migration seasons.

Distribution Range

The Red-breasted Merganser is a North American waterfowl species. It breeds in Alaska and Canada and winters on both coasts of the United States, from California to Maine. In spring and fall, it can be found along the Great Lakes and other inland waters.

Its winter range extends further south than any other merganser species, except for the Common Merganser. It’s also been spotted in Central America, Mexico, Cuba, Bermuda, and some Caribbean islands during migration. Now that we’ve seen where this species lives let’s move on to its habits and habitats…

Habits And Habitats

The red-breasted merganser is an aquatic bird found in freshwater habitats throughout North America, Europe, and Asia. They prefer slow-moving waterways such as rivers, lakes, and ponds. These birds are excellent swimmers and can often be seen floating on the surface or diving for food. They tend to gather in large flocks during migration periods, when they travel from their summer breeding grounds to their wintering areas.

Red-breasted mergansers create nests near the water’s edge and build them out of grasses, leaves and twigs. The female typically lays between seven and eleven eggs which she incubates alone for about three weeks until they hatch. Both parents take turns caring for the young until they are able to fly.

Diet And Feeding Behaviors

The red-breasted merganser is an omnivore, meaning it eats both animals and plants. It feeds primarily on aquatic life such as fish, small crustaceans, and insects. They also eat mollusks, amphibians, and other small aquatic animals. Additionally, they will sometimes snack on plant material like grasses and grains found along the shoreline.

In order to acquire its prey, the red-breasted merganser will dive underwater in search of food. They are able to stay submerged for up to 30 seconds at a time when searching for sustenance. The birds have been observed using their long beak to probe under rocks and other objects for hidden prey.

Their diet is varied and can include:

  • Fish
  • Small crustaceans
  • Insects
  • Mollusks
  • Amphibians
  • Grasses
  • Grains
    By consuming such a variety of items, the red-breasted merganser is able to obtain all the nutrients necessary to thrive in its environment. With these dietary habits established, it’s now time to turn our attention towards its breeding and nesting behaviors.

Breeding And Nesting Habits

The red-breasted merganser is a beautiful duck that can be found in North American waterways. It has a large, dark green head with a bright chestnut-red breast and white neck.
