Learn about swan birds

Swans are a large group of birds belonging to the Duck family, along with geese and ducks. Swans and geese are closely related, and are classified into the Goose family in which swans make Cygnini cardboard. Sometimes, they are classified into a separate subfamily called Cygninae.

Most swans have dark black-colored legs, except for two species in South America, with pink legs. Their color is very diverse: 4 species live in the subarctic region with black mines with irregular gold patches, other species have defined red and black "models" . The white swan and the black swan have a hump at the base of the upper beak.

Northern hemispherical swans have pure white fur, but southern hemisphere swans are white-and-black. The Australian black swan (Cygnus atratus) is completely black except for a few white feathers on its wings and the South American swan neck - as their name suggests - has a black neck. The swan bird can fly at 60 miles per hour.

Swans often stay together for life, but the "divorce" sometimes happens, especially after failing to make a nest. The average number of eggs in each nest is 3-8. It takes 35-42 days for swan eggs to hatch into children. A male swan is called 'cob' and a swan is called 'pen' ( female swan).

A swan bird has 25,000 feathers on you and a male swan is the only bird with a penis.

The most famous story about swans is probably the ugly duckling fairy tale . The story revolves around a young duckling who was treated unfairly until everything was clear that he was a swan and well received in the community. He was mistreated because for many people, the ducklings are actually more adorable than the swans, even though the swans will become mature swans - really charming creatures. Swans are symbols of love and loyalty because of lifelong pairing.
