Sounds of the animal kingdom

Creatures communicate in countless ways, few of which involve spoken language. Calls carry messages about food, allowing creatures to cooperate across the landscape. This flow of signals is the glue of social life.

Voices travel far and reach many listeners at once. Frog choruses can advertise ownership of territory. Repetition often carries added meaning.

Smell may be invisible, but it tells volumes. A great many animals leave traces that advertise their identity, status, or presence. Such signals can persist for days.

Movement conveys mood at a glance. A raised crest can express submission. In tight-knit groups, these signals reduce needless conflict.

Certain displays are vivid and meant to court. Bright plumage help suitors stand out. Reliability in these signals often reveals the sender's strength.

Listening to animal communication deepens our understanding of their lives. Each gesture opens a glimpse into a world full of meaning. With closer study, the more subtle that world appears.
