About Mandarin duck
The scientific name of mandarin duck is Aix galericulata and it is a perching duck species which is native to the East Palearctic. The mandarin duck is medium-sized with 41–49 cm in length and 65–75 cm of wingspan. It is closely related to North American wood duck.
Population of the duck
The mandarin ducks were once widespread in East Asia region. But they were exported on large-scale so the population reduced in the eastern Russia and China. Further, the destruction of its forest habitat further accelerated the reduction in population so much so that the population reduced below 1,000 pairs in each of Russia and China. Japan has an estimated population of around 5000 pairs.
They usually prefers the dense breeding grounds. It usually breeds into the shrubby forested edges of rivers and lakes in low-lying areas. It can also breed in valleys at altitudes of 1500 m. It also breeds in marshes, flooded fields, and open rivers during winters. The duck prefers fresh water but are also seen wintering in the coastal lagoons and estuaries.
