Wolves are forced to work harder for food as winters get warmer

From Earth.com:

Gray wolves don’t just change where they roam when the climate shifts. New research suggests they also change how they eat.

In warmer periods, wolves appear to consume harder parts of carcasses, including bones, as if they’re squeezing every last bit of nutrition out of a meal when conditions make hunting and feeding more difficult.

The study was led by the University of Bristol with the Natural History Museum.
