The emu is a big bird. 

The emu is a big bird from Australia. 

Emus have soft, brown feathers. These feathers help keep them cool in the heat. 
During breeding time, the fathers do the hard work. The male sits on the eggs to keep them warm. This is called incubation. He does not eat or drink much during this time. The eggs hatch after about eight weeks. The fathers then look after the young birds. 
The emu is a very special bird from Australia. 

An emu has a very interesting way of staying comfortable. 
People have been studying emus for a long time. 
There are many facts about how an emu lives.
Emus are a big part of Australian life. 
The emu (Dromaius novaehollandiae) is a large, flightless bird found in Australia. It is the tallest native bird on the Australian mainland. Globally, it ranks as the third-tallest living bird. It is surpassed only by the common ostrich and the Somali ostrich. The emu is the only surviving member of its genus, Dromaius. This genus name comes from a Greek word meaning "racer." This name reflects the bird's incredible ability to run. 
Physically, the emu is built for speed and endurance. It is a robust, bipedal runner with highly specialized pelvic limb musculature. This muscle structure allows the bird to sprint at speeds of up to 50 km/h. While walking, an emu takes strides of about 2 meters. At a full gallop, a single stride can reach 5 meters. Their legs are featherless and end in feet with only three toes. These feet have thick, cushioned pads underneath. To defend themselves, emus use sharp claws on their toes. These claws are used in combat to inflict wounds by kicking. 
An adult emu can reach a height of 1.9 meters. They can also be quite heavy, weighing up to 50 kilograms. Females are usually slightly larger than males. They are also notably wider across the rump. Even though they cannot fly, emus possess vestigial wings. These are small, leftover wings that measure about 10 centimeters. The wing chord is small, and each wing has a tiny claw at the tip. Emus often flap these wings while running to help stabilize their bodies.
Emus have unique feathers that help them survive in harsh climates. Their plumage is shaggy and grey-brown in color. The shafts and tips of these feathers are black. The black tips absorb solar radiation to help with warmth. Meanwhile, the inner plumage acts as insulation for the skin. This system prevents overheating, allowing emus to stay active during the heat of the day. The feathers also provide camouflage. In areas with red soil, the feathers may have a rufous tint. In damp areas, the plumage is generally darker. 
To protect their eyes from dust in windy, arid regions, emus use a nictitating membrane. This is a translucent, secondary eyelid. It moves horizontally from the inside of the eye to the outside. This acts like a visor for the bird. Emus are also omnivores, meaning they eat both plants and insects. They are very hardy and can survive for weeks without eating. While they drink infrequently, they take in large amounts of water when it is available. 
History shows that the emu population has changed significantly. European explorers first reported seeing emus in 1696. This was during an expedition led by Dutch captain Willem de Vlamingh. In 1790, the ornithologist John Latham named the species. He used a specimen from the Sydney area. Many subspecies once lived on islands, but they are now extinct. The Tasmanian, Kangaroo Island, and King Island subspecies disappeared after European settlement. Specifically, the Tasmanian emu became extinct around 1865. 
Today, the emu is a major cultural icon in Australia. It appears on the national coat of arms and on various coins. The bird is also a prominent figure in Indigenous Australian mythologies. While the species is rated as "least-concern" by the IUCN, some local populations face threats. Habitat fragmentation, roadkills, and egg predation by invasive species are all dangers. Despite these threats, the mainland population remains common. In 2009, it was estimated there were between 630,000 and 725,000 emus.
