Red-Breasted Merganser (Mergus serrator )
Red-breasted mergansers are large diving ducks with a long, thin reddish orange bill and an iridescent green head.
Red-breasted mergansers have an average length of 23 inches and an average weight of 2 1/2 pounds.
These birds are most abundant in the northern Atlantic flyway, but can be found in all 4 flyways. They overwinter along the South Carolina coastline.
Red-breasted mergansers spend the summer on fresh, brackish, and saltwater wetlands of the tundra and boreal zones. In the winter these mergansers can be found on secluded bays and estuaries in saltwater environments along the both coasts.
Typical Flock Pattern
The main food consumed by mergansers is small fish and crustaceans. They will also eat worms, insects, and amphibians in smaller amounts.
Pair formation begins in late winter and these late breeders do not begin nesting until late May. The female selects the nest site on the ground near water, usually under shelter or in dense cover. The initial nest is just a scrape, but throughout the nesting period dead grass and litter is added to the nest. The average nest size is around 10 olive buff eggs.
Drake makes a catlike yeow-yeow, and hens produce a raspy krrrr-krrrr call.
- Their flight, strong and direct, is usually low over the water.
- Males are not territorial during the nesting season but protect their mates and nest sites; may nest colonial with same species and with gulls and terns.
- Social throughout the year.
