Red-breasted Merganser

The Red-breasted Merganser is a slender diving duck with a long, narrow red bill whose serrated edges help grip slippery fish. Both sexes have a shaggy crest. A breeding male shows a dark green-glossed head, white neck, rusty breast, black back, and white underparts; the female is greyer-bodied with a rusty head. Juveniles resemble females but have shorter crests and somewhat smaller white wing patches. Adults measure 51–64 centimetres, with males averaging heavier than females.

Breeding takes place beside freshwater lakes and rivers across northern North America, Greenland, Europe, and the Palearctic, with nests hidden on the ground near water. Northern birds migrate to mostly coastal wintering waters, where the species uses salt water more regularly than other mergansers. It dives and swims underwater after small fish, also taking aquatic insects, worms, crustaceans, and amphibians. Eggs are incubated for 28–35 days, and the precocial young leave the nest within a day of hatching. (Wikipedia, Red-breasted Merganser account)
