The booming sound is created in an inflatable neck sac (AM 2001). Breeding pairs form in the summer months of December and January and mating occurs in the cooler months of May and June. An Emus breeding behaviour incorporates male incubation, this is because the male experiences hormone changes. Emus have large multi folded nasal passages for normal breathing in cooler weather. Emus have strong long legs and although they cannot fly, they can run at speeds of 50 kilometres per hour (31 miles per hour). But the Tasmanian emu and King Island emu became extinct shortly after European settlers’ arrived in 1788.
Emu and Human Interaction
Most modern publications, including those of the Australian government (AFD 2008), use Dromaius, with Dromiceius mentioned as an alternative spelling. The emu was first described under the common name of the New Holland cassowary in Arthur Phillip’s Voyage to Botany Bay, published in 1789 (Gould 1865). The species was named by ornithologist John Latham, who collaborated on Phillip’s book and provided the first descriptions of and names for many Australian bird species.
Emu Diet What do Emus Eat?
Thus, it is no surprise that these birds are quite present in ancient aboriginal culture and folklore. All of this power drumming and loyalty tactics set a good scene for an epic emu battle, and in 1932, the Great Emu War was the setting of just that. Their feet have only three toes, each with sharp claws which are used as defensive weapons when needed like the cassowary. Emus are said to be able to run at 50km/h and walk long distances during migrations to new feeding zones. A large bird like this is capable of intimidating and even injuring an adult human, but these events are rare and usually superficial.
Habitat and distribution
Its long, powerful legs, though, allow it to run up to about 30 miles (50 kilometers) per hour. Each emu foot has three forward-facing toes that allow it to grip the ground, thrusting the bird forward. With an estimated population of between 650,000 to 750,000 wild emus, their population is considered stable and not threatened.
- Interestingly, although it is flightless and lacks a keel, it still has tiny 20cm long vestigial wings.
- They live in loose flocks that move according to rainfall and food availability, covering large distances each year.
- However, when food is scarce, these flightless birds may migrate hundreds of kilometres in search of water and food at an average speed of 15–25 km per day.
- The booming sound is created in an inflatable neck sac (AM 2001).
- This colouration helps break up the outline of the chick’s body, camouflaging it from predators.
Emus are omnivores with a diet that varies based on their habitat and the availability of food. They primarily feed on a variety of plants, including leaves, flowers, seeds, and fruits. Emus are also known for their distinctive dancing, which includes jumping and fluffing up their feathers. This behavior is more common in young emus and is thought to be a form of play and exploration, as well as a way to strengthen their muscles and coordination.
Breeding and life cycle
- But there’s so much more to these animals than is commonly known.
- The male sits on the eggs for about 60 days and incubates them.
- This species lives primarily in open regions where they can spot potential predators from afar.
- While farmers do selectively breed their birds for the best meat production and easy handling, they have not undergone selection for a long enough period for people to consider them domesticated.
- Emus are omnivores that feed on seeds, fruits, flowers and insects.
The females, meanwhile, have often moved on, sometimes mating with a different male in the same season. Chicks stay with dad for about four months, until they are able to eat on their own. 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. The common emu may not be able to soar, but for such a big bird it sure can run. This flightless bird has small wings relative to the size of its body.
During this brooding time, the male emu may lose one third of his body weight by not feeding while brooding the clutch of eggs. They usually travel in pairs although they can form huge flocks. They follow a seasonal migration pattern, typically north in the summer and south in the winter although eastern emus seem to follow no pattern at all. Emus have a soft pointed beak adapted for grazing and large eyes which are golden brown to black. 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.
The female then lays 8 to 10 large shiny green eggs that look like avocados and weigh nearly 680 grams each. Emus make deep-throated drumming sounds using a thin-walled 30cm (12in) long tracheal pouch in their windpipe. Adult males usually make a pig-like grunting sound, while adult females make a loud booming sound. Both sexes sometimes boom or grunt during threat displays or upon encountering strange objects.
The emu subspecies that previously inhabited Tasmania became extinct after the European settlement of Australia in 1788. The distribution of the three extant mainland Australian subspecies of D. The Kangaroo Island emu, a separate species, became extinct in the early 1800s, likely as a result of hunting and habitat deterioration. Emus are farmed for their oil, leather and meat, however, emus are common birds with an estimated population of around 725,000.
Emus are diurnal birds, most active during the cooler parts of the day. They are known for their curious and investigative nature, often approaching humans and other animals with inquisitive behavior. You pluck the feathers out first, then pull out the crop from the stomach, and put in the feathers you’ve pulled out, and then singe it on the fire. You wrap the milk guts that you’ve pulled out into something such as gum leaves and cook them. When you’ve got the fat off, you cut the meat up and cook it on fire made from river red gum wood.

Emu: Australia’s Giant Bird
In addition, emus are protected under Australian law, which helps to control hunting and manage any potential threats to their population. Once hatched, the male continues to care for the chicks for up to 18 months, teaching them how to find food and protecting them from predators. The chicks are precocial and can leave the nest within a few days of hatching. Adult emus have few natural predators due to their large size, speed, and powerful defensive kicks.
These birds destroy crops, and wheat in particular is a favorite. 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. Humans utilize these birds in various ways, and one of the primary products that Emu farms produce is Emu oil.
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. In the wild, emus can live up to 20 years, and sometimes longer in captivity. The Emu is currently classified as “Least Concern” by the IUCN Red List. Its population is stable and widespread across mainland Australia. Despite facing habitat loss in some areas due to agricultural expansion and urban development, emus have shown remarkable adaptability to changing environments.
Relationship with humans
Uniquely, males incubate the large green eggs and raise the chicks alone. Emus forage during the day and have a varied diet consisting primarily of fruits, seeds, grasses and shoots of plants like Acacia or Casuarina. They also supplement this diet day trading patterns with animal-based food such as insects, spiders, snails, millipedes, and small animals. Instead, they swallow their food whole and consume occasional pebbles to help break it down in their gizzard.
Sexual dimorphism in emus is minimal, but females are generally slightly larger than males and can be identified by their slightly deeper vocalizations. Another distinct feature of the emu is its three-toed feet, equipped with strong claws, which are used for scratching the ground for food and as a defense mechanism. The Emu, a symbol of Australia’s unique wildlife, stands as the second-largest living bird by height, surpassed only by its African relative, the ostrich.
Emu chicks have distinctive cream and brown diagonal stripes to help them camouflage which will fade after around 3 months. The life span of an emu is between 10 and 12 years in the wild. The Emu is common in mainland Australia but will avoid heavily populated areas, arid land and dense forests. They can survive in most habitats throughout Australia but most common locations are sclerophyll forests and savanna woodlands and grasslands. The most likely entomology for the word “emu” is that it was an Arabic word that early Portuguese explorers adapted as “ema” to describe large birds such as the ostrich.
