Gorilla Behavior

Gorillas are primarily terrestrial. They are social diurnal animals, living in groups called troops. Each troop has 5 to 30 gorillas, led by one silverback. A silverback is an adult male gorilla; the hair on his back turns gray with age. Silverbacks are the strong, dominant troop leaders. Gorillas communicate with each other using complicated sounds and gestures. Gorillas are usually shy and inoffensive animals. Only when provoked or threatened, the gorilla will beat its cupped hands against its chest in an attempt to intimidate intruders.

Gorillas are herbivores. They eat leaves, fruits, seeds, plant bulbs, and flowers. Gorillas spend most of the day resting and eating. Gorillas do not drink water. Each evening, gorillas build nests in trees where to spend the night.
