What is bark the things red pandas eat?

Red pandas primarily eat bamboo, which makes up about 95% of their diet. They also consume fruits, acorns, berries, and occasionally small insects or bird eggs. While they do eat the leaves and shoots of bamboo, they also gnaw on the bark of certain trees, which provides additional nutrients. Their specialized digestive systems are adapted to process their fibrous diet, though they still need to consume large quantities to meet their energy needs.
