They are very silent and avoid contact. They remain in touch with others by the system of Scent-pests . There is a glandular area around the Panda s tail. Which when rubbed against a tree bark leaves a pungent odour. This helps the Pandas to know who has been there and how long ago.
Pandas live in places which have a thick bamboo vegetation.
Those are the only places they can survive in. They survive basically on bamboo. It forms their staple diet. They eat leaves and stems. They are also carnivorous but eat meat only when available which is not often.
