In the very center of Sanski Most near Sana River, a small colony of mandarin ducks, which are unusual for our climate, can be seen this week.

They have never been to these areas before, and because of their appearance they are significantly different from “Bosnian” ducks.

The Mandarin duck is considered to be the most colorful duck in the world, is of medium size and belongs to the group of East Asian ducks and is closely related to the North American duck.

The species was once widespread in East Asia, but large-scale exports and the destruction of its forest habitat have reduced populations in eastern Russia and in China to below 1,000 pairs in each country; Japan, however, is thought to still hold some 5,000 pairs. The Asian populations are migratory, overwintering in lowland eastern China and southern Japan.

Specimens frequently escape from collections, and in the 20th century, a large, feral population was established in Great Britain; more recently, small numbers have bred in Ireland, concentrated in the parks of Dublin.

Now, about 7,000 are in Britain with other populations on the European continent, the largest of which is in the region of Berlin. Isolated populations exist in the United States.

The habitats it prefers in its breeding range are the dense, shrubby forested edges of rivers and lakes. It mostly occurs in low-lying areas, but it may breed in valleys at altitudes of up to 1,500 m (4,900 ft). In winter, it additionally occurs in marshes, flooded fields, and open rivers.

While it prefers fresh water, it may also be seen wintering in coastal lagoons and estuaries. In its introduced European range, it lives in more open habitat than in its native range, around the edges lakes, water meadows, and cultivated areas with woods nearby.
