Canada lynx

The sanctuary said it had lost five African serval cats, four bobcats, two Canada lynx and a Bengal tiger, among others.

Frigid winters, food scarcity, intense competition for territories and the threat of becoming prey to large predators like the Canada lynx are just some of the trials they face.

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research.

The conservationist groups' petition argues that "gunning down wolves from helicopters risks harm to other wildlife like grizzly bears and Canada lynx, as well as public safety and wilderness values."

The researchers also demonstrated that they could distinguish between samples from bobcats and the closely related Canada lynx.
