Physical Description
Emus are large, flightless birds. Their necks and legs are long, but their wings are tiny, reduced to less than 8 inches (20 centimeters). After molting, the birds are dark, but sunlight fades the feathers and they become paler at the end of the season. Chicks have longitudinal stripes with black, brown and cream, so they blend easily into long grass and dense shrubbery. Emus have three toes.
Size
The emu is the second largest living bird and the largest bird found in Australia. Its height averages 5.7 feet (1.75 meters). Males weigh 110 to 121 pounds (50 to 55 kilograms), and females weigh about 11 pounds (5 kilograms) more than males.
Native Habitat
Emus live only in Australia, where they are widespread. Subspecies once existed on Tasmania and King Island, but they are now extinct. Emus live in eucalyptus forest, woodland, heath land, desert shrub lands and sand plains. It is found in desert areas only after heavy rains have caused growth of herbs and grasses and heavy fruiting of shrubs. Emus also live close to Australia’s big cities, but are no longer found where native vegetation has been cleared for agricultural land.
Emu migrations may be a result of human agriculture. The establishment of artificial but permanent watering points in the Australian inland, where cattle and sheep graze, has enabled emus to expand into places from which they were previously excluded by lack of water. In some areas, they are now considered pests.
Communication
Males sometimes make calls, which sound like “e-moo” and can be heard over long distances. Females make resonant, booming sounds.
