Ostriches are large, flightless birds that are native to Africa. They are the heaviest and largest living birds, weighing anywhere between 63.5 and 145 kilograms and reaching up to 9 feet (2.7 meters) in height. They are known for their long necks and legs, distinctive black-and-white (males) or dull grey (females) colouring, and ability to run at speeds of up to 70 km/h (43.5 mph). While ostriches do have a global presence due to farming and captivity, they are not native to Austria.
What You'll Learn
Ostriches are native to Africa, not Austria
The common ostrich is native to large areas of sub-Saharan Africa, while the Somali ostrich is native to the Horn of Africa. Ostriches live in dry, hot savannas and woodlands, and favour lush grasslands over deserts. They are generally quiet, but will make a booming noise when their females or territories are threatened. They live as couples, in family troops, or in small groups of up to 50 birds.
Ostriches have powerful, elongated legs, which they use for running and defending themselves against predators. They can run at speeds of up to 70 kilometres per hour, making them the fastest birds on land. Their legs only kick forward, and one kick is enough to kill a lion or a human. Their long necks enable them to spot enemies from a distance, and they often serve as early warning systems for other animals on the plains.
Ostriches are omnivores, eating vegetation, small lizards, insects, locusts, snakes, and rodents. They also eat sand and pebbles, which help to grind up their food in their gizzards.

Ostriches are the largest and heaviest living birds
Ostriches are native to Africa and are found in desert areas and dry, open grasslands called savannahs. They are also found in captivity all over the world and are farmed in over a dozen countries, including the United States, China, India, Japan, Brazil and Costa Rica.
There are two recognised living species of ostrich: the common ostrich, native to large areas of sub-Saharan Africa, and the Somali ostrich, native to the Horn of Africa. The common ostrich is further divided into several subspecies, including the North African ostrich, the South African ostrich, the Masai ostrich, the Arabian ostrich, and the Somali ostrich.
The ostrich is the only bird with two toes on each foot, while all other birds have three or four toes. They have long necks and legs and are distinctive in appearance, with males displaying bold black-and-white colouring, and females a light brown hue.
Ostriches are omnivores and eat a variety of plants, invertebrates, and small reptiles. They also consume sand and pebbles, which help grind up their food in their gizzard, a small pouch where food is crushed before reaching the stomach.
Ostriches are social birds and live in small groups called herds or flocks, consisting of up to 100 birds. Each group has a dominant male and female, with several other females. During mating season, lone males come and go.
Ostriches are the largest living species of bird and lay the largest eggs of any living bird, weighing up to 3 pounds (1.3 kilograms). Their chicks are also larger than any other bird baby and can be as big as chickens at birth.

Ostriches are omnivores
Ostriches are part of the genus Struthio in the order Struthioniformes, which also includes emus, rheas, cassowaries, kiwis, and the extinct elephant birds and moas. The common ostrich (Struthio camelus) and the Somali ostrich (Struthio molybdophanes) are the only two extant species of ostriches.
Ostriches have incredibly long intestines, measuring 14 to 46 feet, which help them extract as many nutrients as possible from their food. They can go for several days without water, as they get the moisture they need from the plants they eat. However, they will drink if they come across a watering hole.
Ostriches are social birds, congregating in flocks of five to 50 birds during the breeding season and smaller groups of two to five members throughout the rest of the year. These flocks are often found in the company of other grazing animals like antelopes and zebras. Ostriches are very territorial and will guard their territory from outside intruders.
The breeding season for ostriches lasts from March to September. During this time, male ostriches perform elaborate dances to attract females, crouching down and alternating their black-and-white wings. When they are ready to mate, the male's beak and shins turn bright red, and sometimes his neck will change to a red colour as well. Females also change colour, their feathers turning silvery.
Ostriches lay their eggs in a communal nest, with the dominant female placing her eggs in the centre. These eggs are the largest of any species, weighing more than three pounds each. Males and females take turns guarding the nest, with females watching over it during the day and males taking over at night. After an incubation period of 42 to 46 days, the chicks emerge from the eggs already about the size of a chicken.
Ostriches are long-lived birds, with a lifespan of about 30 to 40 years in the wild and up to 50 years in captivity. However, their biggest threat is human hunting, as they are often targeted for their feathers, skin, and meat.

Ostriches can run very fast
Ostriches are the fastest birds on land and the fastest two-legged animals on the planet. They can run at speeds of up to 70 km/h (43.5 mph), with some sources stating they can reach up to 97 km/h (60 mph) in short bursts. Their long legs, which are around 40-55 cm in length, play a crucial role in their speed and stamina. The ostrich's legs contain twice as much elastic energy as human legs, thanks to their lengthy and powerful tendons. The large, well-developed muscles in their upper legs enable the entire length of the leg to swing forward and back at high speeds.
Ostriches also have tremendous stamina. They can maintain speeds of 30-38 mph for around half an hour or longer, which means they could run a marathon in approximately 35-40 minutes. To put that into perspective, the human marathon record is just over 2 hours. Ostriches can cover 5 metres in a single stride, and their large 2-metre wings help them balance and direct themselves while sprinting.
Ostriches are physiologically built for running. Their centre of gravity is perfectly tuned for running, and their powerful legs have evolved to enable them to outrun predators and move between territories in pursuit of food, water, and nesting grounds. Their speed, combined with their excellent eyesight and tendency to live in groups of 5-100, makes them highly resilient to predators.
Ostriches are simply too big and strong to be targeted by most predators. A well-placed kick from an ostrich can kill a lion, and there have been instances of ostriches killing humans. Their legs are formidable weapons, and they are not afraid to use them when they feel threatened or when defending their young.
Ostriches are not only fast but also incredibly agile. They can reach speeds of 60 mph over very short distances, and their slender legs allow them to manoeuvre and change direction with ease. Their slender legs are perfectly placed so that the body's centre of gravity balances on top of them, giving them great stability even at high speeds.
In addition to their speed and agility, ostriches have excellent endurance. They can run long distances without stopping and can sustain speeds of 30 mph for extended periods. Their powerful legs and ability to run for long distances allow them to cover vast distances in search of food and resources in the arid African plains and savannahs.
Ostriches are an impressive example of nature's engineering. Their combination of speed, agility, and endurance makes them one of the most fascinating creatures on the planet.

Ostriches do not bury their heads in the sand
Ostriches do not, in fact, bury their heads in the sand. This is a common misconception and the phrase "bury your head in the sand" has even become an idiom that means to avoid or ignore a difficult situation. This myth likely began with Pliny the Elder, a Roman naturalist who wrote that ostriches have the "marvellous property" of being able to "digest every substance without distinction" but are also remarkably stupid; imagining that when they have thrust their head and neck into a bush, their whole body is concealed.
However, there are a few behaviours that ostriches exhibit that may have given rise to this myth. Firstly, ostriches do not build nests like other birds. Instead, they dig shallow holes in the sand or dirt to lay their eggs. Both parents then rotate the eggs several times a day to ensure they are kept warm. This behaviour may, from a distance, look like they have their heads buried. Secondly, ostriches spend most of their time with their heads close to the ground as they forage for food, including grasses and, occasionally, small animals such as mice, frogs and insects. From afar, this may also look like their heads are buried in the ground. Lastly, when ostriches sense danger, they sometimes lie extremely flat on the ground with their necks extended to blend in with the terrain.
Ostriches are the largest and heaviest living birds, weighing up to 145 kilograms and growing up to 2.7 meters tall. They are also the fastest birds on land, able to run at speeds of up to 70 kilometres per hour. With their acute eyesight and hearing, ostriches can sense predators such as lions from far away. When threatened, they will either hide by lying flat against the ground or run away. If cornered, they can attack with a powerful kick of their legs, strong enough to kill a lion.

Frequently asked questions
No, ostriches do not come from Austria. Ostriches are native to certain areas of Africa and parts of Asia.
Ostriches are found in the wild in Africa, specifically in dry, hot savannas and woodlands. They have been farmed and kept in captivity all over the world.
This myth likely originated with Pliny the Elder, who wrote that ostriches "imagine, when they have thrust their head and neck into a bush, that the whole of their body is concealed." In reality, ostriches lie down with their heads against the ground when they feel threatened, and their heads and necks blend in with the colour of the sand, giving the illusion that they have buried their heads.
