Brown bears are top predators of the taiga, hunting everything from deer to fish. They also like berries, nuts, roots, and other vegetation. During the summer, they eat massive amounts of food, sometimes as much as 40 pounds per day. Their bodies convert much of this extra food and store it as fat. In autumn, brown bears dig dens and begin long winter hibernations, during which they live off the stored fat. (Erik Mandre/ Shutterstock) Read More
