From the side of the runner in motion looks graceful. The unique musculoskeletal system of the bird has interested scientists who are engaged in the development of artificial limbs. The facts about emu. On its strong and high legs, it can run at a maximum speed quite long distances. And this is even though his paw is only two fingers, and one is longer than the other.
One of the fingers is almost imperceptible, a small branch without a fingernail. But the second one has a big massive claw. It serves as a protection for the bird when it strikes a defensive blow to the attacker, and it helps the running bird to gain high speed.
The claw supports the whole body — its contact with the ground helps the ostrich to push away. Specialists say that this is a lot, and confirm that the reason lies in the special structure of their limbs.
Many studies on the ostrich musculoskeletal system are now the basis for the study of the musculoskeletal system in humans. Even though the ostrich wings are underdeveloped, and the chest muscles are weak, and it does not allow them to fly, the leg muscles of these birds are developed so that each step is springy, light, graceful, and yet wide.
The chicks of one month old always follow their mothers and fathers everywhere, even though they are very small in size. It justifies its name because from the look of a clumsy, cumbersome, slow creature is actually very clever and fast. And it does not interfere with its weight or height.
It is possible to catch horses on a turn if you go in a cut, while an ostrich will be difficult to catch not only directly. It develops speed, and for hours does not reduce it despite any obstacles. When the emu gains the maximum speed, he lifts his wings as if he is going to take off. But so he just keeps his balance, and he can never take off — there is no keel, the skeleton is not pneumatic except for the hips , the wings and chest muscles are weak.

Once she has laid her large green eggs, the father will take over the incubation. At this stage she may walk away and never return. Sometimes she will find another partner and breed again.
Meanwhile the father is left to incubate the eggs. In this time he will not leave to drink or eat. He does not leave the nest for two months.

The chicks are fully grown when they are 12 months old and they are able to breed at 20 months. You may see emu chicks being led by their father on excursions in Mungo.
