Winter can be a difficult time for rabbits like these Eastern Cottontails. With their preferred food sources unavailable, they forage farther and expose themselves to greater danger. Rabbits are a favorite prey species of many predators, such as hawks, owls, and foxes, and their life expectancy in the wild is short.
