№ 242-244. Ducks. The extended series.

A Harlequin Duck is a small party-coloured sea duck. The birds live on the slopes near mountain rivers. They build their nests in the thick bushes of alder forest. At the rivers they eat salmons fry and maggots in the litter-banks, at the sea they dive in the inshore water and eat shellfish and cancroids.

A Baer's Pochard lives in the Amur watershed and builds nests at small Seaboard lakes rich with water and inshore plants. During the period of the top increase of the lake water the species abundance decreases. With the beginning of the water recession it rises considerably. During the dry periods it falls again. The total population of this sort of ducks is unknown.

A Common Merganser is a large duck with a long neck and a narrow nib. It lives in the Middle Siberian taiga. The birds build their nests in the splits in the rocks, in old trees hollows and on the ground, but in this case they hide the nests under the brushwood. They mostly eat fish.

The margins of the sheetlet feature the flying ducks, a landscape and blossoming flowers.
