The emu has a pouch in its throat that is part of the bird’s windpipe and is used for communication. When the pouch is inflated, the emu can make deep booming, drumming, and grunting sounds. These calls are usually made during courtship and the breeding season.

Emus are omnivores and look for food during the day. They eat a variety of plants, depending on the season. For example, they eat acacia seeds until the rains come, and then eat new grass shoots and caterpillars.

In wintertime, they feed on the leaves and pods of cassia. Springtime brings beetles, grasshoppers, and fruit. They also eat crickets, ladybugs, lizards, moth larvae, and ants.

Emus form breeding pairs in the summer and stay together through the fall, when the first clutch of eggs is laid. The male builds a rough nest of twigs, leaves, and grass on the ground where the female lays 5 to 15 avocado-green eggs over several days. When finished, the female wanders off, leaving the male to incubate the eggs.
