Mandarin Duck (Aix galericulata), zoological garden of Augsburg, Germany.
The Mandarin duck, a native to East Asia, is like the peacock in that the males of the species have dramatic plumage while the females are generally plainer. While development and large scale trapping have thinned their numbers, they’re still found across a wide swath of East Asia. According to the BBC, they are one of the few duck species that is not hunted or raised for food; apparently they taste awful.
