Значение термина goosander в knolik
goosander - Goosander
goosander - Bill and irides blood-red; head and upper neck glossy dark green; lower neck and under parts white tinged with salmon-pink; upper back and scapulars black; wing-coverts white; primaries and some of the secondaries ash-brown; lower back and tail ash- grey; legs and feet orange-red. Length, twenty-six inches. The female is less conspicuously coloured, and has a reddish brown head and neck.
The mergansers are sea-ducks of slimmer and more elegant forms than the species already described, and differ from scaups, eiders, and scoters as terns differ from gulls. They have grebe-like necks and long, slender, serrated bills, and a variegated plumage with strongly contrasted colours.
The goosander is the largest of the three British species, and is not uncommon in winter on some parts of the coast, and is abundant in the west districts of Scotland. Its visits to the coasts of England and Ireland occur chiefly in severe seasons. It is also a breeder in the Highlands of Scotland. In its summer haunts in Scandinavia and north of the arctic circle the goosander affects rivers and inland lakes, but is also found on the sea-coast. But whether on sea or lake, the water is its element; and being somewhat grebelike in form, with the legs placed very far back, it sits erect, and moves with difficulty on land. On the water it submerges its body when swimming like the cormorant, and, like that bird, preys on fish, pursuing and capturing them under water.
The goosander has a habit very singular in a bird of its conformation and marine habits during the greater part of the year: it breeds in the hollow trunk of a tree. Seebohm relates that the Finns take advantage of this habit, and of the goosander's readiness to make use of an artificial substitute for the hollow trunk, by fastening hollow boxes, with a trapdoor behind, to the trees. The peasant robs the nest daily until a score or more eggs have been taken; the bird is then allowed to keep and hatch any more that may be laid, so that the following year's harvest may not be spoilt. He adds that if there is no hollow tree, and no boxes are provided, the nest is made in a hole under a rock, and that the bird has been known to breed in an old nest of a crow or bird of prey in a tree. "When the nest is at a distance from the ground the parent bird removes her young in her beak, carrying them down one by one, then leading them to the water. The nest is made of weeds and moss, and a quantity of down from the bird is added. Eight to twelve eggs are laid, smooth-shelled, and creamy white in colour.
The call of the goosander is a low whistling cry.
