Who is an ostrich and what is special in it?
Who are ostriches and what they look like today, probably every child knows. And all thanks to the main feature of these birds - a huge size. It is the question of what the largest bird on earth can be found in many quizzes and crossword puzzles. The name "ostrich" in Greek translates to "camel sparrow".Previously, this concept was applied to some species of large birds, for example, to him and the nandea. But today scientists identify them in another group, and ostriches have been given a separate species status and the name is African.
So, the African ostrich is the largest bird of all known today. The average weight of an adult individual may be about 150 kilograms, and its growth may reach more than 2.5 meters. If you look at the photo, you will see that the bird has a large body, a long neck, a relatively small head and large long legs. The ostrich seems a bit awkward and not very sympathetic. But this is only at first glance.
Here is a look at the photo above. Can not you admire them with big beautiful eyes and especially long eyelashes? The ostrich does not know how to fly, he has poorly developed wings, but very large muscular legs. That is why the bird runs perfectly.
How many fingers has the ostrich on the paws?
We think that few people know, and in general, noticed, in addition to the ostrich farmers, how much this bird has fingers and whether it has at all. We answer - has, but unlike all other kinds of birds, they have only two of them: one big and small. On the big toe, as you can see in the photo, not the claw is located, not the hoof. On it the ostrich relies on running.
The fastest runner
In addition to the fact that the ostrich is the largest bird, it is also the fastest non-flying bird. As they say, "born to run, can not fly".Despite its considerable weight, he manages to develop a speed of up to 72 kilometers per hour. And this is quite a lot, as for a two-legged creature. At the same time during the run, the ostrich can easily return without reducing speed, and also suddenly fall on the ground. Such an amazing ability is far from all living beings.
The largest egg
It is not hard to guess that such a huge bird carries and not large eggs. For example, the length of it is an average of 15-20 centimeters, the diameter is also about 15 centimeters, but the weight - up to 1, 7 kilograms. This is the largest egg in the world. However, if we look at the flesh in relation to the body, then in comparison with others, it is the smallest. Here's a pun!
In addition to its size and weight, the egg of the ostrich can claim the title of the most durable. The scallop can withstand the weight of even one adult, average person. This, of course, represents a huge difficulty for the chicks, who have to punch a dense shell for several hours.
There are some features in the ostrich, for example, the growth of feathers. They have a very primitive plumage, and the feathers themselves do not even have a structured opaha. In addition, they grow all over the body evenly. Recall that other flying birds, they are located along the lines of pterilium. This feature is also observed in kiwi, penguins, and he and nande.
What feels like a plumage of the body is that not all areas are covered with feathers. Head, neck, legs and hips naked. Also on the chest is a small area with a meager plumage, the so-called, thoracic cornea. On it the bird relies when it falls or rises from the ground.
Physiological uniqueness of
As we remember, in all birds there is only one way out - the cloaca, which removes from the body both an excess liquid and solid waste. But the ostriches have one more little-known uniqueness among all the birds. In them, excretion of urine and feces occurs separately. In addition, the ostrich is the only bird that has a bladder. They still do not have a goiter, but a long neck allows you to swallow large enough pieces of food or extraction entirely, for example, tortoiseshell.
Where and how does an ostrich live?
Ostrich, having its own feature to run well, chooses open plains, savannahs, semi-deserts for life. They will not be found in dense forests, thickets or deserts with moving sands. They inhabit almost all areas of Africa, with the exception of the northern continent and the Sahara desert. Birds tend to gather in small groups of 15-20 individuals and have a clear hierarchy in the flocks. For example, the main ones are easy to distinguish because they always keep their heads high and straight. Birds of lesser rank are trying to put it down.
Strangely enough, but the peak activity is on the evening twilight. Day and night they sleep. Sleep may indicate in which stage of rest there is a bird. If she sits with her head raised, but with her eyes closed, then she is asleep, if she is lying with her elongated head, she is asleep.
A Distant View of
Very often, along with a group of ostriches, you can see herds grazed by antelope or zebras. This is due to the fact that the ostrich is very cautious bird. Before starting to eat, she stares with her eyes covering all the surrounding area and can see the predator at a distance of several kilometers. As a rule, seeing the danger, the ostrich rushes to flee. And this is also a signal for other herbivores that do not have such vigilance.
Hides my head in the sand?
Today it is believed that an ostrich in the face of danger immediately throws its head in the ground, thinking that in this way it becomes invisible to the predator. An analogous behavior was described in his treatise by the ancient Greek scientist Pliny the Elder. He noted that the ostrich hides his head in shrubs. So, we will not doubt. But today there is no evidence of such behavior. Therefore, we can consider such a statement only as an attempt to explain how a bird eats food. When in danger, the ostrich does not hide its head, but rushes to flee.
Many ostrich scientists know from the rumor that an ostrich is a very violent and aggressive bird. Hiding or escaping from the enemy, it is only in the non-aggressive period, but, if the bird hatches eggs or breeds offspring - it is better not to fall on its path. The ostrich responds instantly to any object moving on it, whether it is a person or a beast. At first, the bird demontically loosens the feathers, and if such a frightful command does not frighten the enemy, it starts to run straight to it. At a meeting, the ostrich strikes his opponent tightly.
It is clear that with such weight, the force of impact is also considerable. For example, in one movement of the foot, the ostrich can break the skull of an adult lion. That is why no African animal is struggling with this ferocious bird. But they use the trick of hyenas and jackals. As a rule, they are grouped together, some distract the adult bird, while others are trying to steal either a chick or an egg at that time. But often opponents get merit.
Ostriches on the farm
Today, in addition to wild boar, ducks, turkeys or geese, ostriches have also settled on private farms. For the first time these birds began to be bred in captivity in the 19th century in South America. Then the ostrich farm appeared in Africa, Southern Europe and North America. Today, ostriches can be found in many private farms and our country. The bird acquired its popularity thanks to its extreme endurance and unpretentiousness.
At the present time, riding on ostriches, and also use them as drag force. Used in meat and poultry eggs in many restaurants in the world. Gourmets claim that meat resembles beef. Also today, due to massive breeding of ostriches of their wild population, nothing threatens.
