They require a lot of water, drinking 2 to 4 gallons daily.
Emus Dromarus novaehollandiae belong to a family of flightless birds called Ratites, they are classed as the second largest bird in the world after the Ostrich.
Emus are the only birds with calf muscles, their strong legs also allow the bird to jump 7 feet (2.1 meters) straight up! Their stride can cover 9 feet and can travel great distances, also sprinting up to 40 mph. The Emu has a knife–like nail on their toes which is used when kicking predators away.
Pairs normally breed from October to April producing 1 egg every 3 days. They can lay between 20 to 50 eggs in a season. The male incubates the eggs, during this time he doesn’t eat, drink or defecate and stands only to turn the eggs which he does about 10 times a day. He also cares for the chicks for the first 18 months. The mating call of an Emu can be heard up to 1- 2 miles away.
Emu eggs are normally dark green and weigh 1.1 to 1.5 lbs.The mature Emu is 5 to 6 feet tall and normally weighs 90 to 120 lbs. An emu's tail feathers are not so soft. Instead, they are stiff and can be rattled by the bird to scare off predators, such as the dingo.
Emus adapt well to temperature extremes from in excess of 100 degrees to below zero.
