Though many bears hibernate when winter rolls around, Panda Bears do not. Because their diet is primarily composed of bamboo shoots, which are very low in nutritional content, when winter comes the panda must continue eating because it is unable to build up the necessary fat reserves.

It is important to note that not all species of bear will hibernate. Bears like the Asiatic Bear live in warmer climates where food is readily available all year long and there is no need to hibernate.
