During the breeding season, male koalas use loud, bellowing calls that consist of a series of harsh inhalations each followed by a resonant, growling expiration. These calls advertise an individual’s presence and warn off other males.
The only vocalization generally heard from females and sub-adult males is a harsh, wailing distress call given when harassed by adult males.
