Almost all black swans are monogamous species. The two mothers together raise a swan and nest in the middle of a shallow lake. The food consists of water plants.
The black swan was first discovered by Willem de Vlamingh in 1697 in western Australia. The discovery of this species caused a great interest among the Europeans, who at that time thought that all the swans were white.
