Understanding PandaTalk Pandas leave their calling card by rubbing or scratching on trees.
Pandas leave messages by scratching or rubbing the bark off trees.
They also communicate with each other by leaving their scent, which is believed to be unique to each panda. At times they can be heard making noises best described as barking, squealing, bleating or roaring. Biologists say pandas bark when they are in danger, squeal like pigs when they are afraid and roar like bears during courtship.
