In the 18th century, ostriches were nearly brought to extinction by hunting because their feathers were very fashionable in women’s clothing. In the wild, ostriches live around 40 years. Males develop a striking black and white plumage while females continue to have a brown plumage. Then around 3-4 years, ostriches reach sexual maturity. When confronted, adults will try to distract predators or lure them away.Ĭhicks are born with a spiky, greyish-brown down. The chicks are born about the size of a chicken and grow 30 cm (1 ft.) each month! By six months, the young ostriches have grown nearly as tall as their parents.Īlthough chicks can run as fast as 55 km/h (35 mph) at one month old, they are still fairly vulnerable to predators like cheetahs, lions, leopards, hunting dogs, and hyenas. If the eggs are kept safe from hyenas, jackals, and Egyptian vultures, they hatch after around 6 weeks. Ostrich eggs are the largest in the world! Each egg is 15 cm (6 in.) long and weighs 1.5 kg (3 lb.). The communal nest may have as many as 60 eggs in it!īoth the male and female ostriches take turns incubating the eggs. The dominant female will lay around 7-10 eggs in the center of the nest, and the other females place their eggs to the outside. Then the dominant male scratches out a shallow pit in the dirt to create a nest. The other hens in the group may also mate with the dominant male or with other lesser males. If the main hen is impressed, the two will mate.
Ostriches also hiss to show their disapproval.ĭuring breeding season (March to September), the dominant male performs a ritualized courtship dance by shaking his wings and tail feathers. From far away, it can be mistaken for a lion’s roar. Ostriches generally live together in groups of about ten, led by a dominant male and a dominant female.
Their presence is useful because they alert other animals when danger is near. Oftentimes groups of ostriches will graze among giraffes, zebras, gnus, and antelopes. Because ostriches have this ability to grind food, they can eat things that other animals cannot digest. They also swallow sand and pebbles which help them grind up their food in their gizzard, a specialized, muscular stomach. Sometimes they consume insects, snakes, lizards, and rodents. Their diet consists mainly of roots, leaves, and seeds, but ostriches will eat whatever is available. Ostriches can also withstand hot temperatures and go for long periods of time without water, usually getting enough moisture from the plants they eat. (Its scientific name is Struthio camelus!) But the similarities do not end there. The pink/peach/grey coloring can blend in with the sandy ground making it appear like their heads are buried.īecause the ostrich has an elongated neck and large protruding eyes shadowed by long lashes, it has been likened to a camel. Sometimes ostriches flop on the ground with their heads outstretched in front of them.
With a 10-cm (4-in.) talon on each foot, their downward kicks can cause serious harm to potential predators.ĭespite popular belief, ostriches do not stick their heads in the sand when threatened. If fleeing the scene is not an option, ostriches use their powerful legs to kick. One stride can span 3-5 m (10-16 ft.)! When confronted with danger, ostriches can usually outrun any animals posing a threat. They can sprint as fast as 70 km/h (43 mph) and hold steady speeds of 50 km/h (31 mph). Unlike other birds, who have three or four toes, ostriches have only two toes on each foot which allows for greater speed. The ostrich is equipped with long, muscular legs built for running. But the ostrich has many unique abilities that make it well-adapted to living in the savanna, desert, and open woodlands of central and southern Africa. Its significant weight, up to 145 kg (320 lb.), prohibits the bird from taking flight. At 2.5 m (8 ft.) tall, the ostrich is the world’s largest and heaviest bird.
