In general red pandas live on their own, but when they do interact with other red pandas, they communicate by arching their tails, bobbing their heads, squealing, or making a sound that scientists call a “huff-quack”—a mix between a duck quack and a pig snort. Pandas who feel threatened may let out a barking sound or release a pungent liquid from glands at the base of their tail.
