This map gives you a rough idea of where you might spot a Emu. The coloured areas show countries where these birds have been seen. The Emu is native throughout Australia and is found in many different habitats. The Australian Museum respects and acknowledges the Gadigal people as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. Booming is created gmarkets in an inflatable neck sac, and can be heard up to 2 km away. It may have been derived from an Arabic word for large bird and later adopted by early Portuguese explorers and applied to cassowaries in eastern Indonesia.
The peculiar structure of the trachea of the emu is correlated with the loud booming note of the bird during the breeding season. Three subspecies are recognized, inhabiting northern, southeastern, and southwestern Australia; a fourth, now extinct, lived on Tasmania. Emus form breeding pairs during the summer months of December plus500 review and January, and may remain together for about five months.
Habitats
- The rooster will watch over the chicks until they are grown.
- Emus also require lots of attention from their owners, so they should be housed with other animals that can give them company while their owners work on other projects or activities.
- They are also known to feed on wheat, and any fruit or other crops that they can access, easily climbing over high fences if necessary.
- They also consume insects, small vertebrates, and animal droppings.
- These sheets were created for teachers, but are relevant to anyone seeking more general information about emus.
The maternal investment in the egg is considerable, and the proportion of yolk to albumen, at about 50%, is greater than would be predicted for a precocial egg of this size. This probably relates to the long incubation period which means the developing chick must consume greater resources before hatching. The first verified occurrence of genetically identical avian twins was demonstrated in the emu. During the incubation period, the egg turns dark green, although if the egg never hatches, it will turn white from the bleaching effect of the sun. Emus forage in a diurnal pattern and eat a variety of native and introduced plant species. The diet depends on seasonal availability with such plants as Acacia, Casuarina and grasses being favoured.
- An emu is a large flightless bird native to Australia and New Guinea.
- The head and neck have sparse, black, bristly feathers, and its legs are long and powerful.
- Newly hatched chicks weigh about 15.5 ounces (440 grams) on average.
- The commercial industry in the country is based on stock bred in captivity, and all states except Tasmania have licensing requirements to protect wild emus.

On top of the sheer size of their legs, a few special features help boost their strength. Emus are unique among all bird species, for example, in having a gastrocnemius. This powerful muscle, located on the back of the lower leg, forms part of what’s known as the calf muscle in humans. Emus are constantly on the move, traveling up to 15 miles daily seeking food and water sources. When searching for food, the usually solitary emu teams up with up to 20 more birds.
Emus are inquisitive birds and have been known to approach humans if they see unexpected movement of a limb or piece of clothing. The pitchuri thornapple (Duboisia hopwoodii), or some similar poisonous plant, could be used to contaminate a waterhole, after which the disoriented emus were easy to catch. Another stratagem was for the hunter to use a skin as a disguise, and the birds could be lured into a camouflaged pit trap using rags or imitation calls. Aboriginal Australians only killed emus out of necessity, and frowned on anyone who hunted them for any other reason.
The Kurdaitcha man of Central Australia is said to wear sandals made of emu feathers to mask his footprints. The Emu was an important source of meat eur usd trading to the Aborigines in the areas to which it was endemic. Emu fat was used as bush medicine, and was rubbed on the skin. It was mixed with ochre to make the traditional paint for ceremonial body adornment, as well as to oil wooden tools and utensils such as the coolamon (Samemory 2008). The largest can reach up to two meters (6 feet 7 inches) in height and 1.3 meters (3.2 to 4.3 feet) at the shoulder).

This even led to an “Emu War” between the Australian military and the native Emu populations! Currently their populations are healthy, and the IUCN lists Emus as Least Concern. As with other ratites, emus have a relatively low basal metabolic rate compared to other types of birds. Emus are diurnal birds and spend their day foraging, preening their plumage with their beak, dust bathing and resting. They are generally gregarious birds apart from the breeding season, and while some forage, others remain vigilant to their mutual benefit. They are able to swim when necessary, although they rarely do so unless the area is flooded or they need to cross a river.
Wonder Sources
During the breeding season, males experience hormonal changes, including an increase in luteinizing hormone and testosterone levels, and their testicles double in size (Malecki 1998). Males lose their appetite and construct a rough nest in a semi-sheltered hollow on the ground from bark, grass, sticks, and leaves. The pair mates every day or two, and every second or third day the female lays one of an average of 11 (and as many as 20) very large, thick-shelled, dark-green eggs. The first verified occurrence of genetically identical avian twins was demonstrated in the emu (Bassett et al. 1999).
Emus track the recent rainfall, so they appear to depend mainly on the sight of and smell of wet grass. Female emus compete for access to males, while males build the nest and wait to be courted. Once a pair has mated, the female lays a clutch of eggs in the male’s nest over several days. The birds were a food and fuel source for early European settlers, and are now farmed, in Australia and elsewhere, for their meat, oil and leather. Commercial emu farming started in Western Australia around 1970. The commercial industry in the country is based on stock bred in captivity, and all states except Tasmania have licensing requirements to protect wild emus.
Males are aggressive when the chicks hatch, driving the remaining females away and attacking anything else that approaches the nest. The emu is common over most of mainland Australia, although it avoids heavily populated areas, dense forest, and arid areas. Emus can travel great distances at a fast, economical trot and, if necessary, can sprint at 50 kilometers per hour (30 miles per hour) for some distance at a time (Davies 1963).
Recent emu research suggests that these birds might be the result of human agriculture. Work is investigating the significance of this data and will continue to monitor this population. Artificial watering points have allowed emus to move into areas they weren’t able to reach before. With a permanent and reliable source of water, they can now thrive in the Australian inland. The variety of habitats these birds reside in is pretty neat and it’s easy to see where there from.
If they can’t find any of their favorite foods, though, emus will eat insects. Unusually among birds, the male is solely responsible for incubation, which lasts about 8 weeks. He also cares for the chicks for up to 18 months, defending them against predators and teaching them to forage. Emus are nomadic, travelling long distances in search of food and water.

At their necks and heads their feathers become sparse and inconsistent, showing greyish-blue skin underneath. The largest of these birds stands over 6 feet tall, and weighs up to 88 pounds or so. Female emus court the males; the female’s plumage darkens slightly and the small patches of bare, featherless skin just below the eyes and near the beak turn turquoise-blue. The colour of the male’s plumage remains unchanged, although the bare patches of skin also turn light blue. When courting, females stride around, pulling their neck back while puffing out their feathers and emitting low, monosyllabic calls that have been compared to drum beats. This calling can occur when males are out of sight or more than 50 metres (160 ft) away.
The male does the incubation; during this process he hardly eats or drinks and loses a significant amount of weight. The eggs hatch after around eight weeks, and the young are nurtured by their fathers. They reach full size after around six months, but can remain as a family unit until the next breeding season.
