Anas marila, Linnæus; Le Milloninan, Buffon; Der Bergente, Bechstein.
This species, like the former, passes in autumn from the north to the south. They are caught and shot among the common wild ducks. The scaup duck may be tamed so far as to remain sociably among the domestic ones, will eat bread soaked in water, oats, and barley; in short, all that is given to common ducks. Its size also is similar, but it is black, with the belly and speculum white; five black transverse lines unite on the white ground of the upper part of the body; the wings and tail are dusky.
THE MALLARD.
Anas Boschas fera, Linnæus; Le Canoel sauvage, Buffon; Der wilde Ente Bechstein.
Our domestic ducks derive their origin from this species. It is spread throughout Europe on lakes, ponds, and rivers. Its length is two feet; its plumage ash grey, striped and waved transversely with white and brown; the head and neck are bright green, known by the name of duck-green; the breast is chestnut brown; the speculum violet green. The female is brown, like a lark.
Observations.—Like other birds of the same order, the wild ducks unite in large flights in the autumn, but divide into pairs in summer, and build their nests either near the water, among the reeds and bushes, in the trunks of old trees, or sometimes even in the depths of woods. They lay from twelve to sixteen eggs. In the forest districts of Thuringia, the young ones are met with in considerable numbers, being led to a neighbouring pond by the parent birds. If, after having mutilated or lamed the end of the wing, they are put into a pond with domestic ducks, they live and pair with them, become accustomed to their mode of life, follow them in winter into the house, without any decoy but being fed plentifully. Wild ducks are taken in nets, snares, and even with fishing-hooks.
By pairing a mallard with a female domestic duck, a very fine middle race is obtained, which remains domestic[125].
