Planet Earth 08 Jungles Part 07

Understanding Animal Communication

The Territorial Calls of Animals

• The calls of certain animals, such as the chairman Gibbons, can travel over a mile and serve as territorial markers, signaling to neighboring groups to stay away.

• The jungle's rich diversity means that many species are attempting to communicate simultaneously, creating a complex auditory environment.

Morning Forest Chorus

• In the early morning, the forest is particularly vibrant with sound; this time enhances the richness of animal calls.

• Sounds can travel further in cooler air conditions, but dense vegetation limits how far most calls can penetrate.
