Ostrich. Ostrich eggs. How fast can an ostrich run? Ostrich head in the sand.
Ostriches are flightless birds. They are characterized by a complete absence of the keel and underdeveloped pectoral muscles; the skeleton is not pneumatic, with the exception of the femurs. The wings of ostriches are underdeveloped; two fingers on them end in claws, or spurs. The hind limbs are long and strong, with only two fingers. One of the fingers ends with the likeness of a horn hoof - a bird leans on it while running.
The plumage of the ostrich is loose and curly. Feathers grow throughout the body more or less evenly. The structure of the pen is primitive: the beards are almost not linked with each other, therefore there are no dense lamina-webs. The head, neck and hips are not supported. On the chest there is also a bare patch of skin, a corn callus, on which the ostrich relies when it falls. The color of plumage in an adult male is black; tail and wing feathers are white. The female of the ostrich is smaller than the male and is painted uniformly - in grey-brown tones; wing and tail feathers are off-white.
They live in groups of 10 to 50 birds. Often with ostriches in the savanna, herds of wildebeest, zebras graze.
Of predators, the ostrich of course flees. Often young ostriches fall to the ground, pulling out their long neck. In such a strange pose the ostrich is hard for the enemy to notice its victim. When the bird has nowhere to retreat, it becomes a dangerous opponent. His strong double-fingered paws are a reliable tool for protection.
Ostriches feed on buds, flowers and small fruits of plants, catch small animals - insects, lizards, small turtles. Since ostriches do not have teeth, to grind food in the stomach, they swallow small pebbles, and often everything that they come across: nails, pieces of wood, iron, plastic, and more.
The male chooses 2-3 females and digs a hole in the sand - the nest. All females lay their eggs there, and then they hatch out in turn. In an ostrich, an egg weighs on average 1.45-1.65 kg and is the largest among birds. The shell of an ostrich egg has a thickness of 1-2 mm and is rather strong. It can only be broken with a hammer or saw. Females hatch eggs during the daytime, since their gray plumage is not noticeable to the predator against the landscape.
Often, ostriches are tamed and retained for the sake of their huge eggs and nutritional meats on special ostrich farms. Ostrich egg cooks 40 minutes. Also a valuable product is ostrich skin. It is well breathable, but retains water. Therefore, ostrich leather shoes provide good ventilation for the feet, while protecting it from getting wet. Ostrich feathers are used as decoration and decoration. Individual enterprises produce souvenirs from ostrich bones (statues, chess pieces, toys).
Decorative tableware, lampshades for lamps, watch cases and other devices are also made from the shell of ostrich eggs. Specialists in alternative medicine recommend the use of growth on the beak and toes of the ostrich as a raw material for medicines. From the viscera of the ostrich, not eaten by humans, produce cat and dog food. The ostrich is a strong bird, an adult male can transport a person without much stress.
An ostrich egg weighs from 1.5 to 2 kg (about 25-36 eggs), while the protein in the egg is about 1 kg, and the yolk is 350 g. The ostrich has the largest egg in the world, and its diameter reaches 15-20 in diameter cm.
The shell of ostrich eggs is very thick, broken reminds shards of dishes. In addition to culinary use, eggs are actively used for decorative purposes. Empty shell is very durable and looks like porcelain. She painted it, make it miniature vases, boxes and other souvenirs. The shell of ostrich eggs was encrusted with precious metals since the Middle Ages, when all this was used as ceremonial and extravagant glasses. The color of the yolk is saturated, the protein is translucent.
Ostriches carry eggs in the summer, and eggs cannot be reached at other times of the year. In order to cook an ostrich egg "cool" you need 75 minutes. The caloric content of ostrich eggs is lower than that of chicken. 100 grams of ostrich eggs contains 118 kcal, which makes them quite nutritious. However, dieters should not get carried away because of the high fat content of the product.
How fast can an ostrich run?
Everyone knows that these big birds can't fly. But on the other hand, they completely compensate for the omission of nature with the ability to run very fast. The ostrich is the only bird of its kind, able to develop great speed. Ostrich is a record holder in running. And all this thanks to his powerful legs.
In the wild, the maximum recorded ostrich running speed is more than 64 km per hour, according to the US National Wildlife Federation. The ostrich is the largest bird in the world, which does not know how to fly and has to rely on the speed of its run in order not to fall into the hands of predators. The average running speed of an ostrich is about 50 km per hour; this is the speed at which it is able to cover distances of up to 16 km. When threatened or trying to escape from a predator, the ostrich is able to develop even greater speed. Although lions and cheetahs can run faster at short distances, nevertheless, ostriches are the fastest two-legged animals in the world.
On large, high and strong legs, he travels very long distances. At the same time it has only two fingers: one small one is almost imperceptible, the other one is big with some kind of claw. This special tool helps the bird not only to defend itself, but also to run well. Gaining great speed, the ostrich with the help of this claw is in good contact with the ground, making various maneuvers.
In ordinary cases, for example, these birds develop a speed of 50 kilometers per hour for crossing the terrain. Experts believe that so quickly the birds can run due to the special structure of the limbs. Muscles allow these feathery to make very light and graceful, but big steps. It seems that they do not run, but simply easily kick their feet. One step is about 4 meters.
While running, ostriches very economically expend their energy, which allows them to maintain a stable high speed for a long time. As it turns out, no other animal or bird possesses this ability today. The highest speed of the ostrich, which was recorded is 92 kilometers per hour. This is almost half the size of their usual running and is truly a record.
In the wild nature of Africa, no predator dares to attack a bird, therefore it is rare when an ostrich can be seen in clashes. This is primarily due to the personal safety of animals (an ostrich can easily kill a paw with one blow), as well as character. In case of danger, they prefer to leave or run away rather than fend off their paws and claws. Due to the very advanced vision and hearing, they notice the danger several kilometers away and immediately flee. In such cases, the bird reaches a speed of about 70 kilometers per hour. With such a run, their stride width exceeds 7 meters.
The ostrich can keep such speed at short distances, then reducing it to 50 kilometers per hour. By the way, kids run with the same speed. Already at the age of one month they can run after mom also at a speed of 50 kilometers per hour.
What is the height of an ostrich?
Ostriches are the largest birds. From the tips of the paws to the crown, the height of the ostrich is 1.8-2.7 meters. In height, this bird resembles a horse.
Ostrich head in the sand
There are several versions of why everyone thinks that ostriches hide their head in the sand. To speed up its digestion, the ostrich eats up to 2 kg of stones a day, often leaning towards the sand to eat the stones, so it may seem that it hides its head in the sand. In other cases, the ostrich bows its head to the ground in order to listen to someone approaching it or not. Ostriches live in packs and rest in turn.
While some relatives sleep, others guard and closely monitor the approach of dangers. Due to their great growth and good eyesight, they notice the danger from afar, reporting about the approach of a predator to relatives who are resting at this time. The fact that ostriches hide their heads in the sand is nothing more than a fiction invented by soldiers of ancient Rome. The expression "to bury my head in the sand" was due to ostriches.
