Description

Emu (Dromaius Nivaehollandiae) is a soft – feathered brown, three-toed feet bird, with a dark grey head, long necks and legs. The flightless bird is stated to be able to reach a height of 6.2ft with an estimated body weight of 66 to 100 pounds.

Like the camel who can travel for days without resting, the emu is long-distance travelers as well. It can travel great distances and have been known to go for weeks without eating. However, they drink water infrequently when the opportunity arises.

Unlike most birds who have one feather per follicle, the emu grows a double-shafted feather from each follicle with similarities to hairlike appearance. Its feathers are less water-resistant than other bird feathers, and its tail feathers are usually stiff.

The three-toed feet bird is considered to have long and powerful legs, that allows it grips, thrust itself forward and make a run to cover an estimated distance of 31 miles (50 kilometres) per hour. An adult female Emu has been studied to be larger and heavier in size than an adult male emu.

Habitat

The population of the emu is currently considered stable. Emus are known to be primarily found in Australia. Three subspecies are recognized to be inhabiting northern, southeastern and southwestern of Australia.

They have also been found to occupy parts of new guinea, Indonesia, Solomon Islands and in the Philippines, while a now extinct emu lived on Tasmania.

Feeding and reproduction

Emu

Emu is an omnivorous animal and is known to feed on a variety of plants and insects depending on the season.

They eat acacia seeds until the rain comes, and then eat new grass shoots and caterpillars. In the wintertime, they feed on the leaves and pods of cassia, while in springtime, they feed on beetles, grasshoppers, and fruit.

They also eat crickets, ladybugs, lizard, moth larvae and ants. Their feeding process in its habitat is considered to be important as they serve as seed dispersal specialist.

The reproduction of Emus takes place usually in May and June. Female emus are known to fight viciously for a mate, especially unpaired males.

Mating pairs remain together for up to five months, after which female, lay several clutches of eggs in one season. They are usually large, emerald-green or dark shiny green eggs having a resemblance to Avocado.

The females often wander away to mate with another, while the male is left to incubate and nurture the eggs for about seven weeks without drinking, feeding or defecating.

Behaviour and predators

The emu possesses a pouch in its throat, that is part of the bird’s windpipe used for communication.

When the pouch is inflated, the emu can make deep booming, drumming and grunting sound usually made during courtship and breeding season.

A hiss described as blood curing is effective at warning off dingoes. When cornered, they kick with their big three-toed feet to keep predators at bay. It will also rattle its tail, to also scare off predators.

Predators of emu include dingoes, foxes, wedge-tailed eagles. Snakes and other nest-raiders feed on the emu eggs, while humans feed on their meat, eggs and nurture them for their oil and leather.

Drought and wildfires are also potential threats that could affect them.
