Other names: Mute swan, Cygnus olor
Where did it come from?
Mute swans are native to Europe and were brought to North America to decorate urban parks.
Why is it invasive?
These birds are highly aggressive and will chase both humans and native birds. In addition, they out compete native birds for food resources with their voracious appetite.
How do you prevent its spread?
These swans are still intentionally released in many areas. Support efforts to choose native swans for parks instead of mute swans.
