Adult ostriches are about 2.5 meters tall and weigh about 130 kg. Its legs are thin and long, and it is effortless to support the ostrich body weighing 200 kilograms. Their wings are very small, just playing a balance role in running. The ostrich's head is very small, but its neck is particularly slender, and it feels like shaking its head when it moves. Strong legs have no feathers, stand on two toes, and the big ones are hooves. This is the unique adaptability of ostriches. In order to cope with the sudden danger, they run very fast. Ostrich's huge eyeball, with thick black eyelashes, is the largest eyeball among terrestrial creatures, and only whales are bigger than him. The running speed and endurance of ostriches are amazing, and young ostriches born soon can run very fast. Ostriches live in groups in desert areas and desert grasslands in Africa, and males usually lead several females to live. Because there is little cover on the prairie, ostriches are often attacked by tigers, lions, leopards and other large fierce animals outside, and they will die. So ostriches also live in hot water every day.
Let's talk about the next generation of ostriches-ostrich eggs. An ostrich egg is generally15cm long, 8cm wide and weighs1.5kg.. The longitudinal diameter of eggshell is about15-16cm, and the transverse diameter is about11-13cm. It is round and smooth, milky white, with ivory-like texture and luster. Moreover, ostrich eggs are harder than ordinary eggs, and they are also one of the largest eggs among birds.
Now many people are killing ostriches, and the number of wild ostriches is gradually decreasing. I want to remind you: please protect the ostrich, the largest bird in the world, and hope it will continue to be our good friend for generations to come.
2. About the 400-word ostrich composition friends, I am an ostrich. You must have heard my name. In the zoo, you looked at me curiously, hoping to see me hide my head in the sand and make you laugh!
Actually, you really don't know me very well. But it's not your fault, because in cartoonists' works, I always bury my head in the sand and show my body to avoid danger. They use this to ridicule those fools who dare not face reality and deceive themselves. This is really a misunderstanding of mine.
I am the largest bird in the world, with long legs, long neck and a height of more than 2 meters. Because of the degradation of wings, I became a flightless bird, but I have a pair of "Scud". I can walk dozens of kilometers an hour on land, so people often regard me as their means of transportation like riding a horse.
I am bald, with a long neck, round eyes, a flat mouth and a flat chin, so some people say that I am a gentleman, while others say that I stand tall and show my hips, like a posh and arrogant lady. In fact, I hold my chest out and my hips out just because the feathers on my chest and tail are particularly fluffy and naturally spread out. It's not that I want to put on airs. When I feel abnormal, I don't lift my head very high, but lie on the ground to observe the movement. Careless people think I escape from reality.
Today, I want to solemnly declare here that this is our ostrich's living habit, not stupid and pretentious. You should never listen to hearsay and misunderstand us again.
I am a little ostrich. Every day when I have endless homework.
Looking up at the blue sky, several chirping and cheerful birds glided past my eyes and played freely. I just want to be a happy bird.
If I were a bird, I wouldn't stay in my room and do these endless homework. Will fly to the cloud to play games with Yun Yun's sister; Follow the sun and see the beauty of the earth; And tell stories with the wind.
If I were a bird, I would fly to the big forest. Look at those towering trees, exotic flowers and herbs.
Build a gentle home on a big tree, make friends with all the animals in the big forest and sing together. Let the big forest be a sea of joy.
If I were a bird, I would fly to adults and sing for them, so that my singing can take away their diseases and troubles. I hope they can be moved by songs and lead children to love birds and forests in nature.
It was a sunny morning, and my parents took me to the park to play.
We came to the animal area and saw many birds, the most conspicuous of which was the ostrich. An ostrich has sharp eyes, a sharp mouth, a thin and long neck, and black feathers, like a small black skirt.
Ostriches are fun to eat! I put an apple on the guardrail and saw it step back two steps, as if it were scared. When it thought I meant no harm, it pecked the apple at once.
After catching the food, it ate it with relish. Although the ostrich is not as beautiful as other birds, I still like it very much.

The third toe is thick and big, like a carrot. The ostrich's feathers are black and its body is slightly round, like a big egg! We were playing on the nearby grass when someone suggested, "Let's pull some alfalfa and feed it to the ostriches." As soon as we heard it, it was a good idea, and everyone applauded. So each of us pulled out a handful of alfalfa and fed it to the ostrich. I send alfalfa to the ostrich's mouth. When the ostrich saw it, it immediately picked it up with its long, pointed mouth and put it next to it. That funny action made us laugh! At this moment, I saw an uncle holding a big ostrich egg in his hand. I'm surprised. That was the first time I saw such a big egg! This ostrich egg is about15cm long,10cm wide and 8mm thick. It is said that a person standing on it will not break! Besides ostriches, there are turkeys, pigeons, guinea fowl and other animals. It seems that ostriches have a lot of companions! Just as we were having fun, the adults said, "Dinner is ready. Come and eat. " At this time, I feel hungry, and my stomach is singing with me. I can't wait to be seated. I saw, wow, the table was full of all kinds of food, including a big plate of chicken, braised fish and the special dishes here: ostrich meat and ostrich eggs, which made our mouths water. I can't wait to rush over and eat it. I picked up a piece of ostrich meat and put it in my mouth.
Unconsciously, time flies and the day is coming to an end. I reluctantly left the ostrich villa. Before I left, the staff gave me a complete empty ostrich eggshell as a souvenir. I hope to come again next time.

Ostrich: A huge African bird (Ostrich), which can't fly but can run very fast. It is characterized by a long hairless neck, a small head and two toes on its feet. It is the largest living bird in the world.
The largest bird among modern birds is 3 meters tall, with a long neck, a small head, a long naked neck, a flat mouth, short wings, inability to fly, long legs and strong feet, and is good at walking and running. Female birds are grayish brown, and male birds have white feathers on their wings and tails. Living in the grasslands and deserts of Africa.
The ostrich is the largest existing flightless bird. Produced in Africa. It belongs to Stru-ionic type of Ostrich. The male bird is about 2.75 meters tall and weighs 155 kg. The neck length accounts for almost half of the body length, and the female bird is slightly smaller. Ostrich eggs are the largest eggs in modern times. Male feathers are mostly black, but their wings and tail feathers are white; Most females are brown. The head and neck are mostly reddish to light blue; Micro-feather: small head, short and slightly wide beak; Big eyes, brown, thick black eyelashes. They live on the desert grassland. Live in groups and travel daily. He has a keen sense of smell and hearing and is good at running. When running, he can help by flapping his wings. He can stride 8 meters at a speed of 70 kilometers per hour and jump 3.5 meters at a time. It feeds on plant stems, leaves, seeds, fruits, insects, worms, birds and reptiles.
Ostriches often live in groups of 5-50, often accompanied by herbivores. Ostriches use powerful legs (only two toes, the main toe is almost a hoof) to avoid enemies. When frightened, the speed can reach 65 kilometers per hour. If it is too late to escape, they will bury their heads and necks in the sand and pretend to be rocks or bushes. If you are desperate, kick your opponent.
Ostrich mainly feed on plants and can live for a long time without drinking water. Males compete with each other for 3~5 females, making a roar and hiss. Medieval knights liked to decorate their helmets with ostrich feathers. Ostrich skin can be made into soft and fine leather. Therefore, ostrich farms were established in South Africa, the southern United States, Australia and other places, but after World War I, the industry declined. After training, ostriches can ride and drive single-seat two-wheeled vehicles. Ostriches are not easy to adapt to captive conditions and can live for 50 years. Ostrich is a typical flightless bird. Ostrich in different places are slightly different in skin color, body shape and egg characteristics. Previously, people thought they were different species, but they were actually only subspecies of ostriches.
Ostrich fossils are found in Pliocene strata in southern Russia, India and north-central China.
