The silverback Ziz feeding on bamboo
He pulls bamboo shoots from the ground, peels them and chews them.
Humming and singing
With such sounds gorillas show comfort and pleasure, for example when they find especially favoured food.
Belching
This soft grunting is the most usual vocalisation. By belching, the gorillas keep contact to each other and communicate different kinds of information.
Crying
A gorilla baby cries because it wants to drink milk.
Alarm
When a silverback male is alarmed, he emits a characteristic sound.
Play with chuckling
Young gorillas are wrestling.
Playing males
Even adult males sometimes engage in playful wrestling, in this case it is Ziz and Pablo.
Chestbeating with hooting
Display of a silverback male
Coughing
This aggressive vocalisation is emitted to warn conspecifics or to rebuke them.
A conflict in the group
Two females have a dispute, other group members also take part in the conflict and the leading male tries to resolve it.
