Dromaius

Dromaius is a genus of large, flightless birds in the order Casuariiformes native to Australia. The genus is most widely recognized for its sole living representative, the emu, whose scientific name is Dromaius novaehollandiae. Fossil records document additional extinct relatives assigned to the same genus, illustrating a longer historical presence on the Australian continent.

Emus are among the tallest and fastest birds in the world. They typically stand about 1.5 to 1.9 meters tall, have long necks and legs, and carry gray-brown plumage. Their powerful legs enable rapid running, with top speeds reaching around 50 kilometers per hour. They have three-toed feet adapted for traversing open terrain.

Distribution and habitat extend across much of mainland Australia, especially in open grasslands, savannas, and lightly wooded areas. Emus are adaptable and can exploit a variety of water sources, but they avoid dense forests and heavily human-modified landscapes when scarce resources are available.

Ecology and behavior: emus are omnivorous, feeding on a mix of grasses, seeds, fruit, flowers, insects, and occasional small vertebrates. They are nomadic in search of food and water, often traveling long distances in arid regions. They are social but may form loose groups outside the breeding season.

Reproduction: breeding involves a nesting male incubating a clutch laid by a female over several days. The egg incubation lasts about eight weeks, after which the male raises the chicks. Females may begin new breeding cycles after laying, with the males and chicks forming a multi-month, if loosely organized, family group.

Taxonomy and status: Dromaius belongs to the broader Casuariiformes lineage, closely related to cassowaries. The emu is listed as Least Concern by major conservation bodies, though local populations can be affected by habitat loss, drought, and predators. The genus name derives from Greek roots meaning swift runner.
