At the end of 15 months, these would yield 4 square metres of leather, 150 kg of meat, 5.5 kg of feathers, and 2.7 litres of oil. Eggshells of infertile eggs have been used for carving. Emus move within their range according to climatic conditions. If sufficient food and water are present, birds will reside in one area. Where these resources are more variable, Emus move as needed to find suitable conditions. They are known to move hundreds of kilometres, sometimes at rates of 15 km to 25 km per day.

- They also prefer regions with easy access to water, so they avoid deserts and desert edges.
- It is omnivorous and forages on a variety of plants and insects, and can go for weeks without eating.
- There have been other attempts to shoot or poison large numbers of emus over the years, but the birds have proven resilient and resourceful.
- For such a bulky bird, however, their wings are surprisingly puny.
- Both sexes are brownish, with a dark gray head and neck.
However, Emus are not really social, except for young birds, which stay with their father. 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. 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 tracheal pouch is over 30 cm long and very thin-walled, and it allows the bird to produce deep guttural grunts. This pouch develops fully during the breeding season and is most frequently used during courtship. The emu’s call can be heard from more than 100 metres away. In the wild, they eat fruits, flowers, insects, seeds, and green vegetation; they also love caterpillars, mice, and lizards. To aid in their digestive process, they will swallow stones. On our farm, we fed them a specially formulated grain pellet containing numerous natural supplements to optimize health.
Humans Once Lost a ‘War’ With Emus
The eggs are dark green and shiny, with small pits on the surface. Emu farming has been tried for several decades but recently interest has been growing in this industry. A pair of Emus may produce ten eggs a year under good captive conditions, which yield on average 5.5 chicks.
This is a social time for them
They have blue colored skin on their long necks which is visible through their thin neck feathers. They have 2 concealed wings and a highly specialized pelvic limb musculature which aids their ability to run so fast. When temperatures are very hot, the emu pants to help maintain its body temperature. The Emu is the second largest bird in the world, the largest being the similar looking, Ostrich.
Emu Conservation Status
Immelmann noted that a sleeping emu looked like an anthill from a distance, suggesting this trait may be an effective camouflage. According to Immelmann, the emus would retire at sunset, then spent up to 20 minutes squatting in bed before getting into their sleep position. Once in a deep sleep, however, “the Emu seems insensible to the reception of noise or visual stimuli,” Immelmann wrote. In 1932, a group of 20,000 emus were searching for water in Western Australia when they came upon the state’s recently expanded wheat farming region. The emus began to damage swaths of wheat plus the surrounding fences, which meant rabbits and other animals could get in.
- In zoos and farms, these birds live in large enclosures with fencing at least six feet tall.
- Each emu foot has three forward-facing toes that allow it to grip the ground, thrusting the bird forward.
- The tracheal pouch is over 30 cm long and very thin-walled, and it allows the bird to produce deep guttural grunts.
- He becomes aggressive once his chicks hatch, chasing away any females in his territory (including the mother) and attacking any perceived threat to his nest.
- The emu’s range also includes New Guinea, Indonesia, Solomon Islands, and the Philippines.
Breeding and life cycle
During this time, while he will defend the young birds, the male is also tolerant of other lost chicks joining his flock. Males do both, and in exchange, he has access to multiple hens, who, between them, will compile a clutch of up to 25 emu eggs that the male will then incubate. Fowl are relatively known for the guttural drumming noises, but a full-grown female emu has even a large turkey beat when it comes to banging the cans. Emus are part of a diverse order ranging from the humble kiwi to the largest birds that ever roamed the earth. They’re one of the many ratites that evolved to be enormous, and they handle it well.
The special nature of these feathers enables emus to cope with extreme changes in weather. All ratites have flat breast bones (no keel) and no wing muscles, so they cannot fly but have instead developed solid legs for running. While naturally docile and curious, Emus can use their legs equipped with three-toed dinosaur-like feet for defense. Emus have three main calls, a throbbing drum (by the female), a grunt (by the male), and a whistle (by the chick). Those unique legs can take enormous strides, enabling emus to run at speeds up to 30 mph (48 kph). Emus also have an impressive vertical leap, which can quickly carry the large birds up to 6.8 feet (2.1 meters) off the ground — all without the help of wings.
Each emu foot has three forward-facing toes that allow it to grip the ground, thrusting the bird forward. A powerful kick is also handy for keeping predators at bay. He seldom leaves the eggs during this period and can lose a considerable amount of weight. He waits until they are all hatched before he and his chicks leave the nest site. During their first 4 days outside the shell, the chick only needs to eat or drink once they have fully metabolized the yolk sac.
Though infrequently, they also hunt small animals like lizards, snakes, and mice. Before the breeding season, males bulk up and build their fat stores so they can survive the nesting period. Emus are omnivores, which means that they feed on both plant and animal matter. They forage for seeds, berries, fresh grasses, and fruits, but usually do not eat leaves. These birds also hunt for a variety of small creatures, like grubs, spiders, beetles, grasshoppers, millipedes, caterpillars, and more.
These calls are usually made during courtship and the breeding season, heard up to 1.2 miles (2 kilometers) away! A hiss, described by one of our animal behavior specialists as bloodcurdling, is effective at warning off dingoes. Winhangadurinya is an experiential space, a complex arrangement of three dimensional objects with deep meanings, including these carved emu eggs. It lives throughout most of the continent, ranging from coastal regions to high in the Snowy Mountains. Emus were once found in Tasmania, but were exterminated soon after Europeans arrived. Two dwarf species of emus that lived on Kangaroo Island and King Island also became extinct.
The life span of an emu is between 10 and 12 years in the wild. 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 calculated bets 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.
What do Emus eat and how do they communicate?
Predators of the emu include dingoes and wedge-tailed eagles. Snakes and other nest-raiders devour emu eggs, but they’re not the only ones. One emu egg can make an omelet big enough to feed four to six adults.
Their pelvic limb muscles are also particularly massive, accounting for as much of their total body mass as the flight muscles do for most flying birds. 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. They also eat crickets, ladybugs, lizards, moth larvae, and ants.
