Oh dear, I've also heard that ostriches don't have big eyes, so don't you think they're stupid?

An ostrich is a bird, an ostrich is an oviparous animal, its eggs have a well-developed blood circulatory system, and they breathe with their lungs, the definition of birds in biology: "homeothermic animals, oviparous, covered with feathers all over the body, streamlined body, beaks, eyes on both sides of the head, forelimbs degenerate into wings, hind limbs have scaly skin, and have four toes", so, from a biological point of view, an ostrich is definitely a bird.

The ostrich is one of the largest birds in the world, with adults up to meters tall and males weighing up to 150 kilograms. The snake-like neck supports a small head with a short, flattened, triangular mouth made up 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's extant birds, 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.

History of the ostrich

The history of human contact with ostriches can be traced back to ancient Egyptian, Assyrian, and Babylonian times, when ostrich feather trade was recorded.

In China, as early as the Eastern Han Dynasty, there were records of ostriches being paid tribute from the Western Regions, and ostrich stone carvings were also unearthed in the tomb of Li Yan of Tang Wuzong.

And the Bible mentions ostriches very frequently. During the Crusades of the 13th century in Europe, ostrich feathers became one of the trophies, and ostrich feathers were also worn in portraits of Henry VIII and Edward VI.

In the late 18th century, Marie Antoine of France began the custom of high society to decorate with ostrich feathers. In the 19th century, this trend spread to England by Elizabeth I, but after the First World War, due to the economic downturn and the boycott initiated by nature lovers, coupled with the emergence of chemical fibers, the feather** plumage** fell sharply.

Ostriches are birds. Ostriches are bipedal oviparous animals, forelimbs evolved into wings, vertebrates with hard pecking, ostriches meet the definition of birds, and ostriches are currently the largest living birds in the world, and they are also a flightless bird, but they run fast.

The habits of ostriches.

Ostriches generally refer to the African ostrich, which is the largest bird in the world and the only two-toed bird in existence.

The African ostrich lives in the desert meadows of Africa, generally distributed in dry areas with low rainfall, and has a mixed diet, mainly feeding on plants.

The African ostrich has a well-developed air sac and circulatory system to regulate body temperature, so it can adapt to arid or hot environments and has a good ability to tolerate heat.

Ostrich is a bird, belonging to the flat-chested general order birds, its body length is about one meter eight to three meters, the head is small, the neck is long, the mouth is yellow, the eyes are brown, mainly distributed in Eurasia and northern Africa, breeding ostriches to choose an open terrain site, and provide it with leeks, yellow grass, rye grass and other green fodder.

1. It belongs to birds

Ostriches are birds, belonging to the flat-chested order of birds, their height is more than two meters, their necks are longer, their heads are smaller, their bodies are larger, their legs are strong and powerful, but they are not good at flying and running, and ostriches have high economic value, and their fur can be used to make clothing.

2. Distribution area

Ostriches are mainly distributed in Eurasia and northern Africa, and their main countries are Egypt, Nigeria, Somalia, South Africa, Sudan, Zimbab, etc., and ostriches inhabit deserts, grasslands, shrubs, and occasionally appear on steep stony plateaus.

3. Reproduction method

After the ostrich enters the breeding season, the female will actively approach the male and mate with him, and after the mating is completed, the female will lay the fertilized eggs in a nest built in the ground, and wait for 40 days before the ostrich eggs will hatch.

4. Breeding technology

Breeding ostriches should choose an open, ventilated and sunny site, and need to create a clean and hygienic, dry and warm growth environment for it, in the process of breeding, should provide feed for ostriches twice a day, mainly green fodder such as leeks and ryegrass.

Ostriches are birds. By definition, birds are bipedal, homeothermic, oviparous, feathered, forelimbs that have evolved into wings, and have a hard beak. A bird fits this definition, and an ostrich fits that definition.

In terms of physiological characteristics, the skeleton of birds is hollow and highly healed, except for the flat-chested order (that is, a type of bird represented by ostriches), the outer thoracic body is swollen and the bones are developed, which is convenient for the attachment of the pectoral muscles; body surface feathers; When breathing, a microtrachea is used for gas exchange, with an air sac; toothless, with bursa and gizzard; The digestive system is short and uses uric acid for nitrogen metabolism. Ostriches also have these physiological traits.

Morphological characteristics: African ostriches are about 183-300 cm long, 240-280 cm tall, weigh 130-150 kg, and females are slightly smaller. It has a peculiar appearance, with a small head supported by a slender snake-like neck, a short, flattened triangular mouth composed of several sheaths, with a yellow upper mouth and a slightly pink lower mouth, and two large brown eyes like frog's eyes.

The torso is stubby, the sternum is flattened, there is no keel protrusion, and there is a pair of short wings that seem to be very disproportionate to the body, which has been degenerated, has no flight feathers, and cannot fly, but during the breeding period, the male must show off the feathers of his wings when he courts the female, and during the hatching and brooding period, the adult bird must have two wings so that the eggs or chicks are not exposed to the blazing sun, and can also open to strengthen their momentum and frighten the enemies who dare to attack.

Ostriches are birds.

Ostriches belong to the ostrich family of the order Ostriches and are one of the largest birds in the world, with adults up to meters tall and males weighing up to 150 kilograms. The ostrich has a small head supported by a snake-like slender neck, with a short, flattened triangular mouth composed of several sheaths, and is mainly characterized by the underdeveloped keel process, which cannot fly, and is the only two-toed bird in the world.

Ostriches live in desert meadows and savanna areas in Africa, and are widely domesticated in many countries because of their high economic value in plumage, skin and meat, fast growth, strong fecundity, easy feeding and strong disease resistance.

The habits of ostriches.

Ostriches are able to adapt to arid climates because of their well-developed air sacs and good circulatory system to regulate their body temperature, and they are exceptionally heat-tolerant, even when temperatures are as high as 56, they can still forage for food in the scorching heat of the day, and they can go months without drinking water. The most active times are in the early morning and dusk.

Ostriches run fast in the desert, with distances of up to meters per step, a continuous run speed of 50 kilometers per hour, can run for more than 5 minutes, sprint at a speed of more than 70 kilometers per hour, and can also cross obstacles more than 5 meters high.

Ostriches eat a very mixed diet, but mainly on the stems, leaves, fruits, etc. of plants, especially flowering shrubs, parasitic creeping plants, ground creeping cucurbitaceae and wild figs, etc., and also eat insects, mollusks, small reptiles, birds and mammals, etc., while eating some sand grains to help digestion.
