Adult females will often use this time to give birth to a litter of cubs. Newborn cubs are born blind, toothless and nearly hairless, and they spend the rest of the winter snuggled up to their mother s thick fur, nursing on her milk, which is rich in fat. By the time spring arrives many bears have lost up to a quarter of their body weight, so when they wake up they re as hungry as you guessed it bears. Red Foxes Many animals migrate or hibernate when their favorite foods are unavailable. Not the red fox.
Foxes are omnivores, which means they ll eat just about anything.
When their primary foods fruit and insects are gone in the winter, foxes simply look for something else to eat, such as snakes, rodents, rabbits, squirrels, birds or whatever else they can catch. The foxes often hide leftovers under leaves or bury them in a hole to be eaten later. In winter, foxes often den in abandoned woodchuck or badger holes, which are usually very deep up to 40 feet. There, they breed. The female gives birth to anywhere from four to ten pups in early spring.
