Trumpeter Swan Killed by Gray Wolf in Minnesota

Posted on

Canis lupus (Gray Wolf) have been suspected as natural predators of Cygnus buccinator (Trumpeter Swan), but detailed descriptions of such predation events are lacking from the peer-reviewed literature. Herein, we document a Trumpeter Swan that was killed by a Gray Wolf fitted with a GPS collar in northern Minnesota, thus confirming that wolves are natural predators of Trumpeter Swans.
