Ostriches are flightless birds native to Southern Africa.
They are the largest living species of bird, growing to an average of 3.5 meters (11.5 ft) and weighing as much as 120 kg (264 lb).
Ostriches are herbivores, and can run at speeds of up to 40 km/h (25 mph).
The fastest ostrich ever recorded was an ostrich called Mr. Happy who ran at speeds of up to 70.7 km/h (43.99 mph) in the Australian Outback in 1972.
Ostriches are the world's fastest running bird.
Ostriches are among the fastest animals on Earth, which is great if you have an endless supply of bushmeat to eat—but terrible if you're an ostrich farmer.
Anyhow, their legs are made of stronger than steel, and can run over 100 mph.
This is made possible by the fact that the thigh bone is much longer than it is wide, which lets the limb spread out like a fan to generate the extra muscle force.
The only problem is that these legs don't match how they would look if they were shaped like our own.
This speed is part of a survival mechanism.
When an ostrich is being chased by a potential predator, it kicks off with its powerful legs and keeps running until it has put enough distance between itself and the biggest predator for it to be safe.
Humans would appear to be outmatched in a race with an ostrich, as the bird is the fastest land animal and can reach speeds of up to 70 km/h, whereas the fastest humans can only run at a speed of around 45 km/h.\
There are two reasons why humans cannot outrun ostriches.
In the ostrich species with the highest top speed, the greater and the common ostrich, the males are the more speedy of the sexes. In the remaining species, the female ostriches are faster.
An ostrich can run faster than a cheetah as it is the fastest of all birds and can run at speeds up to 70km/h.
A cheetah can run up to 70km/h but cannot sustain it for long as it has a small heart and a small lung capacity.
Despite the fact they are both considered to be the fastest animals in the world, the cheetah and ostrich are quite different from each other, especially when it comes to their bodies and running styles.
Cheetahs are known to be faster over short distances.
Ostrich is a much faster runner over long distances.
Ostriches are characterized by their long legs, which can make them look quite awkward when trying to move around.
But ostrich legs also enable them to run much faster than their size would suggest, and to travel great distances.
In fact, a male ostrich can run at speeds up to 45 km/h, and it takes a full hour for an ostrich to run a mile.
To achieve this speed, they need to be able to walk and run at the same time.
Ostrich feet contain four toes which are connected by a large number of strong bones.
Each toe may also have a claw, which helps them to grasp the ground when running.
Ostriches are large, long-legged birds.
They are one of the largest living species of birds.
They are not used as pets in most places.
Because of the similarities between ostrich in appearance, there is some confusion over the question of whether emus are ostriches.
Ostriches are one of those tempered creatures.
They can be friendly, but they can also be aggressive.
They'd rather run away from you than challenge you, but if you try to mess with them they can be a little bit aggressive too.
They can be domesticated, but they can also be a bad pet.
The African ostrich is the world's largest living flightless bird, significant for its distinctive physical feature, the feathers of its wings.
The African ostrich is the national heaviest bird of several African countries, especially those that are also members of the African Union.
Although it is a fairly large flightless bird, it is not particularly fast, but it is quite maneuverable.
The ostrich can run at speeds up to 59 km/h (37 mph), though it can only sustain this speed for a few minutes.
Ostrich eggs are particularly adapted to weather extremes, since they can survive for many months without water.
Arabian ostrich is a flightless bird in the ratite family.
The Arabian ostrich is one of the three species of ostrich. This ostrich species is native to Arabian Peninsula.
It lives in a wide range of habitats, from arid deserts to wet savanna, and has adapted to these environments with features that allow it to survive.
The Arabian Ostrich, also known as the Greater Ostrich, is the largest species of ostrich and has the largest brain of all birds, with a weight of over 200 pounds.
Somali ostrich is a species of ostrich that is native to East Africa.
It is smaller than the common ostrich, and is commonly found in the southwestern tip of Somalia.
The Somali ostrich is one of the most threatened species on Earth.
The birds are named after their African homeland, and are endangered and distinctive birds as a result of habitat loss, hunting and poaching.
To add to their woes, the species has a high susceptibility to a fungal disease called avian malaria.
This species of ostrich is characterized by having a very long neck and the ability to run at speeds in excess of 60km/h (40 mph).
This speed is not attained by simply sprinting, as this can strain the bird's muscles and tendons.
Instead, the ostrich gradually builds up speed over a long distance.
The bird uses its long legs to get a clear run and then uses its wings to gain steady speed.
For this reason, ostriches can reach speeds of more than 50km/h (30 mph) on flat ground, and up to 70km/h (43 mph) when flying.
