The body weight can be up to 155 kg.

Females are slightly smaller in size. Ostrich eggs are 125 mm long in diameter, 150 mm in length and weigh kilograms. It is the largest of all the eggs now.

When it is pressed, it will kick with its feet and pose a great threat to the opponent.

Ostriches are mainly plant-eating, and sometimes dare to catch some animals. You can survive without drinking water for a long time. During the breeding season, males share a litter with 3-5 females.

If an outsider peeps at it, it will let out an angry roar or hiss to drive away the intruder. Their nests are built on the ground and lay 15-60 white bright eggs in one nest. At night the male bird sits and guards it, and during the day it is the turn of the female.

Baby ostriches emerge after 40 days of hatching. In another month, they will be able to run with the adult birds. In order to avoid danger, the baby ostrich, like the bird, will lie in the ground and hide, only sticking its head out.

This habit was later mistaken for ostriches burying their heads in the sand when they were in danger.

In the Middle Ages, knights wore an ostrich feather in their helmets. In the 19th century, it became an ornament for ladies' clothing. This demand has prompted farmers to set up ostrich-keeping farms in places like South Africa, the southern United States, and Australia.

It was only after the First World War that the ** of ostrich feathers stopped. Ostriches have also been trained to carry animals and race, but they have no stamina and are not easy to train well. Raised ostriches can live up to 50 years.

Depending on the species, the size and skin color of the various ostriches and the size of their eggs differ. During the Pliocene epoch (about 5 million years ago), ostriches were widely distributed on Earth. Ostrich fossils have been found in the southern part of Russia, India and the central and northern regions of our country.

The West African ostrich and the Arabian ostrich are endangered. It is also believed that the Syrian ostrich, native to Syria and the Arabian Peninsula, became extinct in 1941.

The introduction and characteristics of the ostrich are as follows.

1. Introduction to ostriches.

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, flat triangle of sheaths.

of the mouth. The keel process is underdeveloped, unable to fly, and is 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.

Second, the characteristics of ostriches.

The ostrich is characterized by its large species of bird, with a slender neck, a small head, a short, flattened, triangular beak made up of several sheaths, the upper beak stained yellow, the lower beak slightly pink, brown eyes, large eyes, a stubby torso, and a sternum.

digestive properties. Due to the fermentation of its digestive tract, it can obtain nutrients from feeds with high crude fiber content such as grass better than other poultry, and can maximize the digestion and absorption of nutrients in food. Ostriches do not have a gallbladder, but it does not affect the digestion of fat by adult ostriches, and this digestive characteristic should be paid attention to when preparing ostrich feed, so as not to obese adult ostriches.

Ostriches like to live in groups. It is often one male and multiple females. The primitive living environment of ostriches is desert and meadow, and they have the habit of preferring sand bathing.

1 Wide adaptability.

Ostriches are native to the African and Arabian deserts and grasslands, and the harsh climate and natural conditions have created a unique ability to adapt to the environment. Ostriches can grow and reproduce in conditions ranging from -30 to 45. It can be sustained by feeding in small quantities in extreme grassland poverty.

2. Highly gregarious.

Ostriches often live in small flocks of 5-6 males during the breeding period, and usually in groups of 0-15 females, sometimes as many as 40-50 individuals. When a flock of ostriches is feeding or drinking, it is common to see at least one ostrich visiting and saccade, and the ostrich will only bow its head to eat and drink when the other ostriches look up, and this rotation takes only a few seconds. A similar phenomenon occurs when sleeping.
