Giant Pandas live in humid bamboo forests or forests with a mix of coniferous and deciduous trees, at altitudes of 1300 to 3600 meters. Both males and females live alone most of the year, and do not hibernate like bears do. Giant Pandas sleep for 10 to 16 hours per day, and spend most of their waking hours eating bamboo shoots and leaves. Occasionally a Giant Panda will eat insects or small animals. The Giant Panda has a protrusion on its wrist, which the Giant Panda can use like a thumb. This "sixth finger" is perfect for grasping bamboo stalks. Giant Pandas are excellent tree climbers, and often climb trees to avoid enemies. However, they are not very good at climbing down from trees, and often fall in the process. Giant Pandas have black fur around their eyes and on their ears, nose, shoulders, arms, and legs. Other areas of their bodies are covered by white or cream-colored fur. Their tails are white as well.
