DESCRIPTION
Bewick's Swan (Cygnus columbianus bewickii) is commonly known as the Tundra Swan.

FUN FACTS
- Bewick's Swans are named after the English naturalist Thomas Bewick, who was known for his detailed illustrations of birds
- They are remarkable migrators, traveling thousands of kilometers from their breeding grounds in the Arctic to wintering areas in Europe and Asia, often flying in a distinctive V formation.| These swans are known for their strong family bonds, with young swans staying with their parents for several months after hatching
- This social structure helps them learn essential survival skills and increases their chances of survival during migration
