Emu Facts, Diet, Habitat, Reproduction, Eggs
The Tasmanian, Kangaroo Island and King Island subspecies became extinct after the European settlement of Australia in 1788. The emu breeding season is dictated by the shorter days of the cooler Australian outback winter. The female lays an egg in the nest, which the male will cover with leaves and grass. 3-4 days later, she will lay another egg and repeat this until there are 8-10 eggs in the nest. The female may then find a second mate to start a second clutch.

Ostriches, on the other hand, are far more distantly related to emus, despite being closest in size. The Kiwi of New Zealand (not the fruit) is a strange and charming little flightless bird that doesn’t appear to have an ounce of intimidation in it. They also make the best noise of any animal on two legs. Thankfully, these quirky little weirdos are doing quite well, though climate change does seem to be making their lives more difficult. Domestic emus are playful, mischievous birds that have a specific kind of excited wiggle that they do when they’re enjoying themselves. Emus are part of a diverse order ranging from the humble kiwi to alvexo forex broker the largest birds that ever roamed the earth.
First, the male builds a rather basic nest consisting of a slight hollow in the ground lined with trampled bark, grass, sticks and leaves. The female then lays 8 to 10 large shiny green eggs that look like avocados and weigh nearly 680 grams each. 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.

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. The male parent emu cares for his chicks for up to 18 months, and most survive to adulthood. Emu chicks follow their father everywhere, whistling softly to each other and eating what is free margin in forex tender plant shoots.
- Both sexes sometimes boom or grunt during threat displays or upon encountering strange objects.
- They can walk just minutes after hatching and can leave the nest at about three days old.
- In classic human fashion, the colonists set up shop uninvited among the native habitats and then got upset by the natives being there.
- They need shrubs or trees for their food, however, so they do not live in open areas with no plants.
Top 20 Unusual Animal Facts
- The emu has two long, thin legs, each ending in three large toes with prominent toenails.
- The first occurrence of identical bird twins was discovered in the emu.
- Once the eggs hatch, the male emu will stay with the chicks for the next 18 months, teaching them to hunt for food.
- Three subspecies are recognized, inhabiting northern, southeastern, and southwestern Australia; a fourth, now extinct, lived on Tasmania.
- Sometimes ceramic ostrich eggs were substituted for the real thing if they were unavailable.
They reach full size after around six months, but can remain as a family unit until the next breeding season. Emus form breeding pairs in the summer and stay together through the fall, when the first clutch of eggs is laid. The male builds a rough nest of twigs, leaves, and grass on the ground where the female lays 5 to 15 avocado-green eggs over several days. When finished, the female wanders off, leaving the male to incubate the eggs. It’s a good thing he ate extra food to build up his reserves of body fat before the breeding season! He stays on the nest for the next eight weeks, getting up only to turn the eggs and tidy the nest.
The emu is lighter than its relation, but taller and less heavy-set. The chicks will stay under the father’s care for another seven months, and this is the largest grouping of emus that typically occurs before the groups are split up. As long-legged, flightless birds, you’d expect emus to be fast. These are accomplished walkers and runners and cover vast distances bipedally.
But there’s so much more to these animals than is commonly known. One tale tells of the creation of the sun by throwing an Emu egg into the sky. In more recent times, the birds have been adopted as an icon in Australia, and they have been featured on many different products and organizations. Emus in human care eat a commercial ratite feed that provides all the nutrients that they need.
An emu father may lose a third of his body weight while incubating his eggs. 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. Breeding takes place in May and June, and fighting among females for a mate is common. Females can mate several times and lay several clutches of eggs in one season. 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.

A hen can be productive for 20 years, laying between 20 and 50 eggs a year. They can walk just minutes after hatching and can leave the nest at about three days old. But they usually stay with their father for about 18 months. The father teaches them how to find food and stay safe from dingoes and foxes. The chicks’ striped feathers help hide them from danger. Emus are full-grown at 12 to 14 months but don’t reach sexual maturity until about 2 years of age.
If sufficient food and water are present, birds will reside in one stan weinstein’s secrets for profiting in bull and bear markets 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. Humans utilize these birds in various ways, and one of the primary products that Emu farms produce is Emu oil. Historically, Australian aboriginals hunted these birds as a source of food for decades. Though infrequently, they also hunt small animals like lizards, snakes, and mice.
Even a truck-mounted gun failed when the emus outran the truck over rough terrain. They need shrubs or trees for their food, however, so they do not live in open areas with no plants. These big, beautiful flightless birds are the second largest birds in the world (the ostrich is the largest). The emu, being a flightless bird known as a ratite, lacks an extension to its sternum (breastbone) called a keel on which flight muscles are usually anchored. Interestingly, although it is flightless and lacks a keel, it still has tiny 20cm long vestigial wings.
Incubation
This struggle closes down the web-like blood supply extending throughout the eggshell inner lining. This blood supply exchanges oxygen and carbon dioxide through the surface while the embryo grows. The struggle also assists in the internal absorption of the yolk sac through the chick’s belly button.
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 in an inflatable neck sac, and can be heard up to 2 km away. The main habitats of the Emu are sclerophyll forest and savanna woodland. These birds are rarely found in rainforest or very arid areas. 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.
