Ostriches live in nomadic groups of 5 to 50 birds that often travel together with other grazing animals, such as zebras or antelopes. They mainly feed on seeds and other plant matter; occasionally they also eat insects such as locusts. Lacking teeth, they swallow pebbles that help as gastroliths to grind the swallowed foodstuff in the gizzard. An adult ostrich typically carries about 1 kg of stones in its stomach. Ostriches can go without water for a long time, exclusively living off the moisture in the ingested plants. However, they enjoy water and frequently take baths.

With their acute eyesight and hearing, they can sense predators such as lions from far away. When being pursued by a predator, Ostriches have been known to reach speeds in excess of 70 km per hour (45 miles per hour), and can maintain a steady speed of 50 km per hour (30 miles per hour).

Ostriches are known to eat almost anything (dietary indiscretion), particularly in captivity where opportunity is increased.

Ostriches can tolerate a wide range of temperatures. In much of its habitat, temperature differences of 40°C between night- and daytime can be encountered. Their temperature control mechanism is more complex than in other birds and mammals, utilizing the naked skin of the upper legs and flanks which can be covered by the wing feathers or bared according to whether the bird wants to retain or lose body heat.

When lying down and hiding from predators, the birds lay their head and neck flat on the ground, making them appear as a mound of earth from a distance. This even works for the males, as they hold their wings and tail low so that the heat haze of the hot, dry air that often occurs in their habitat aids in making them appear as a nondescript dark lump. When threatened, Ostriches run away, but they can cause serious injury and death with kicks from their powerful legs.

The most unique behaviour occurs when a pair of ostrich bearing young meets another pair. The parents will fight and the winning pairs will be parents of both pairs' offspring. It has been reported that the biggest group of ostriches contains 300 offspring(wiki)

Hello Annick!
Yesterday I tried to take picture of such bird. But it was too far for my lens, so detail and sharpness were very bad.
You portrait is wonderful!

this cheeky chappy looks a bit like my emu, and looks as if he could do with a bath.

A very great macro of this bird, with excellent sharpness and details.
Best wishes,
Achim

Bonjour Annick
Très beau portrait d'autruche.
Belle netteté et arrière plan bien flou pour faire ressortir le sujet.
Cordialement
