Shaun bellowing One of our keepers caught this fantastic video of Shaun bellowing. Koalas have evolved a unique additional pair of vocal cords which enable them to make such deep sounds. Male and female koalas can bellow, but it's usually male koalas bellowing to attract a mate. Bellowing lets koalas tell each other where they are and warn other males that there is a male present in the area. #RockhamptonZoo #koala #bellow | Rockhampton Zoo
