The Life of Animals | Merganser | Besides fish, take a wide variety of aquatic prey such as molluscs, crustaceans, worms, larvae of insects and amphibians, less frequently, small mammals and birds can be adopted. As in other birds with the character, the salmon pink hue variable shows men probably related to diet, derived from carotenoid pigments found in certain fish and shellfish. In most places, the merganser is almost as good a salt water fresh water goer.
In small streams, are found in pairs or small groups, and float down, circling in the rapids, or fish with strength in some deep pool at the foot of a waterfall or rapid. When floating quietly, which are placed in the water like ducks. But swimming in deep water as cormorants too, especially if you're swimming upstream. Often the fish in a group that forms a semicircle, and drive the fish into a shallow, where they are easily caught. In areas without trees (such as the mountains of Central Asia), using the holes of steep and high cliffs, banks, sometimes at great distances from water. The ducks are taken from his mother in his bill to rivers or lakes soon after hatching, where they feed on freshwater invertebrates and small fish fry, when fledging 60-70 days old.
The species is a partial migrant, with the birds away from areas where large rivers and lakes freeze in winter, but live where the water open. Eastern part of North American birds south in small groups in the United States ice conditions on lakes and rivers, there is freedom, smoother on the Pacific coast, they are permanent residents. Scandinavian and Russian birds migrate to the south, but the West European birds, and some in Japan are largely established. In particular, most of the Western European male population migrates north from estuaries in Finnmark in northern Norway (mainly Tanafjord) to the suit, allowing the females to ensure the ducks.
In Western Europe there was a clear spread south from Scandinavia in the field of breeding in 1850, to colonize in Scotland in 1871, in England in 1941, and also a large increase in population in the Alps A small breeding population was recently Ireland.
