The Mute Swan (Cygnus olor) is native to Eurasia and was an introduced species to North American parks and estates. Escaped individuals have established breeding populations outside of captivity and their aggressive behavior poses a great threat to native waterfowl.

Because of their strength & aggressiveness, Mute Swans have very few natural enemies to help control their rapidly increasing populations.

Mute swans compete for resources with other waterfowl such as loons, ducks, colonial waterbirds, tundra swans & geese and will sometimes completely displace, or even kill, native waterfowl.
