Swan bird

Swan bird
The swan is a large type of water bird from the genus Cygnus in the Anatidae family. Short-necked ducks and geese also occur in the family Anatidae. Geese and short-necked geese belong to the Anserinae subfamily, but this type of goose has its own tribe, the Cygnini tribe. There are seven species of birds in the genus Cygnus. Swans are monogamous animals, 'divorce' sometimes occurs when the nesting process fails.
