    Usually the ostrich always stretches its neck to look through the mist, and once frightened or detects the enemy, it simply sticks its periscope-like neck flat to the ground, curls up its body, and disguises its dark brown feathers as stones or bushes, plus the cover of the mist, it is difficult to be detected by the enemy. In addition, the ostrich keeps its head and neck close to the ground, which has two functions: one is to hear distant sounds, which is conducive to avoiding danger early; Second, it can relax the muscles of the neck and better eliminate fatigue. In fact, no one has ever actually seen an ostrich bury its head in the sand, which would suffocate the ostrich to death.

    When the ostrich is frightened, the first reaction is not to run away, but to bury the head in the sand, which is a bad habit developed by their ancestors in ancient times, thinking that it is like a shame to steal the bell, blindfold others will not see themselves, if there is no sand, they will also choose to put their heads in the leaves, it is because of this, the hunter in the desert catches the ostrich not to shoot, but to strike a very loud gong near the ostrich, the ostrich listens to bury its head, and then the hunter comes out and twists it hard, and the neck of the ostrich is broken!

    The ostrich sticks its head into the sand because it wants to eat some sand to help digest the food in the stomach.

    To avoid danger, ostriches will lie underground and hide, sticking only their heads out. This habit was later mistaken for ostriches burying their heads in the sand when they were in danger. Ostriches do not avoid their enemies because they are afraid of danger.

    Studies have shown that ostriches protect themselves by skillfully using the intense light layer formed by the reflected light produced by the intense sunlight shining on the desert surface and the diffuse reflection of the hot air.

    It hides its body beneath the light layer, and its head is like a periscope watching for the enemy's movements. If spotted by an enemy, the ostrich will fight back. Relying on its tall body and strong legs, it can compete with the sharp javelins of the natives, and fierce beasts such as lions and cheetahs cannot kill it in a short time.

    Ostriches bury their heads in the sand, usually to swallow stones.

    This is because ostriches have no teeth, but they have unusual stomachs, and they will swallow small stones in large quantities to break up food to help digestion, while the stones will remain in the stomach and not be excreted.

    Ostrich's digestive system:

    The digestive system of an ostrich is composed of the oropharyngeal cavity, esophagus, glandular stomach, muscular stomach, small intestine, large intestine, cloaca, liver, and pancreas. There are no lips and teeth, replaced by beaks; The esophagus is easily dilated and there is no bursage; The glandular stomach and the muscular stomach are directly communicated by the large glandular gastric muscle appetite; The cecum has two; The liver has no gallbladder.

    Many people know that when the ostrich encounters danger and does not have time to escape, it will put its head and neck flat on the ground or bury it in the sand. People ridicule the comical behavior of the ostrich and use the term "ostrich policy" to describe people who dare not face reality. In fact, people misunderstand ostriches.

    If frightened or aware of an enemy, the ostrich will lay its neck flat on the ground and curl up in a ball, which is actually a way for the ostrich to use its dark brown feathers to disguise itself as rocks or bushes in times of crisis.

    The African ostrich (scientific name: Struthio camelus) belongs to the ostrich family of the order Ostriches and is the largest bird in the world, with adults up to 2 years tall5 meters, male ostriches can weigh up to 150 kg.

    The slender neck like a snake supports a small head, with a short, flattened, triangular mouth composed of several sheaths, the main feature is that the keel process is underdeveloped, unable to fly, and it is also the only two-toed bird in the world, with dangerous toenails about 7 cm long on each big toe of its feet, and its hind limbs are thick and powerful, suitable for running. Living in the desert grasslands and savanna areas of Africa, it is widely domesticated in many countries because of its high economic value of plumage, skin and meat, fast growth, strong fecundity, easy feeding and strong disease resistance. <>

    The ostrich is the largest living bird, weighing more than 100 kilograms and reaching a height of more than 2 meters. It is indeed difficult to lift such a heavy body into the air, so the large size of the ostrich is a reason that hinders its flight.

    The ostrich's flight organs, which are different from other birds, are another reason that prevents it from flying. The flying organs of birds mainly have wings, feathers, etc., which are changed from the forelimbs, the feathers really have the function of flying in the feathers are the flight feathers and tail feathers, the flight feathers are long on the wings, the tail feathers are long in the tail, this feather is composed of many slender feather branches, each feather branch is densely born with rows of feather branches, there are hooks on the feather branches, and the feathers are hooked together to form feathers, and the feathers fan the air and make the birds fly in the air. The tail feathers born on the tail can also be connected by feather hooks to form feathers, which play the role of rudder in flight.

    In order for the birds' flight organs to function properly, they also have a tail fat gland, which secretes oil to protect the feathers from deformation. The way that the feathers of the birds that can fly are born on the body surface is also very particular, generally divided into feather area and bare area, that is, some areas of the body surface are distributed with feathers, and some areas do not produce feathers, and this way of feathers is conducive to vigorous flying sports. The feathers of the ostrich have neither flight feathers nor tail feathers, and there is no feather maintenance device - tail fat glands, and the feather growth mode is all evenly distributed on the body surface, without the distinction between feather area and bare area, its flight organs are highly degenerate, and it is impossible to talk about flying if you want to fly.

    The laws of nature are inexorable, adaptable and irresistible. If the ancestors of the ostrich had been holding on to flying over the empty desert, rather than looking for something to eat in the desert, they would have become extinct long ago. Taking a step back, if nature had settled the first ancestors of ostriches in the woods instead of deserts, the ostrich might not have become a flightless bird, but perhaps it wouldn't have been called an ostrich either.

    The reason why large ostriches can't fly into the sky is not because their wings don't work, but because their feathers are too soft and their wings are too small to fly.

    In addition, the ostrich's muscles are underdeveloped and the sternum is flat, which is not helpful for flight.

    Ostriches live in Africa, and because they have lived in desert areas for a long time, their bodies have gradually evolved into their current state in order to adapt to their environment.

    Why can't ostriches fly?

    The ostrich weighs too much, and it is too difficult to fly into the sky on its own. The wings of the ostrich have degenerated, becoming very small and lacking in strength, while the ostrich's flight feathers and tail feathers have been severely degenerated, these two feathers are the key to flight, so the ostrich cannot fly.
