Hello, everyone. I'm glad to introduce myself to you. My name is ostrich.

My head is small, wide and flat, like a compressed biscuit. My neck is long and flexible. Don't think it's sausage from a distance! My "bald head" and arms, as well as my long straight legs, are usually pale pink; The beak is straight and short, and the tip is oblate. I have two black pearl eyes, inherited the characteristics of birds, and our eyesight is also very good, with thick eyelashes blinking and flying around. How's it going? Are we pretty?

Someone described us like this: "Running so fast in the desert, even a fast horse is hard to catch up." Yes, we are well-deserved long-distance runners. Why are we good at running instead of flying? We are the only birds with only two toes in the world. The outer toes are as small as stones, and the inner toes are particularly developed, so you can race with cars. Jumping can reach three meters, and one step can span about eight meters! The sprint speed is above 70 kilometers per hour. We also have a secret defense weapon, that is, our thick legs, which are extremely powerful in times of danger and can even kill lions and leopards!

We are never picky about food. Grass, leaves and fruits are my favorites! Sometimes they also eat some small animals and insects, which are omnivores. We often bury our heads in the sand, like a shy little girl. It's normal to eat some sand. Eating sand helps us digest!

Because of our poor reproductive ability and the threat of natural enemies, our population is getting smaller and smaller. Maybe one day you can only see us in the zoo. How sad it will be!

"I am a bird that can't fly. I have a long head and legs and run fast in the desert. Even the fast horses can't catch up." This is our ostrich.

My head is small, wide and flat, and my head and neck are as long as a snake, but very flexible! My hind legs are strong and I am good at running, but I only have two toes. Among birds, we have the least toes, which is one of our differences.

Although we have wings, we can't fly like other birds. In fact, our ancestors could fly, but after years of evolution, our flying ability gradually deteriorated.

Although I can't fly, I am an athlete! I can fly 25 meters and cross 8 meters in one step! I can sprint more than 70 kilometers per hour, which is enough to catch up with the speed of city cars! Sometimes we run around leisurely in the desert, sometimes we look in the mirror by the oasis, and sometimes we play happily with the children ... It's really leisurely!

We are not picky about food. Grass, insects, roots, seeds, leaves, fruits and snakes are all my favorite foods. I am an omnivore, but our digestion ability is poor. We will eat some sand grains. Don't worry about me. Eating sand will not only hurt the spleen and stomach, but also help digest food! Ha ha! You must think we are wonderful animals!

When the enemy or sandstorm comes, we can't help burying our heads in the sand, so they can't hurt me. Look, I'm smart!

Actually, I still have many secrets! It's too late to introduce it to you today. If you are interested, you can check the information online!

Birds are not birds, they can't fly, but they are running champions. Do you know who it is? Haha, this is me-ostrich.

My head is small, wide and flat, and my neck is long and flexible, which can be compared with the giraffe's neck! I might as well tell you that although I am tall, I am actually very timid. Whenever something happens, my head will involuntarily drill into the sand. Well, don't laugh at me for being a coward!

My hind legs are big, but I only have two toes, which is different from ordinary birds with three or four toes. So I have the least number of toes among birds! But the inner toe is much bigger than the outer toe.

Don't underestimate me. If I take part in the long jump and running in the Olympic Games, I will be the champion! You know, I can cross eight meters in one step, and the sprint speed is over 70 kilometers per hour! Sometimes I walk easily in the desert, sometimes I take part in running competitions with my companions, sometimes I chase and play with my children on the grass, and sometimes I enjoy my beautiful image and various beautiful shapes by the oasis where flowers are blooming! Life is so leisurely!

You will definitely ask me what I usually eat! I have all kinds of nutrients. The staple food is grass, leaves and seeds ... as long as we can eat, we will eat and will not be picky about food. Sometimes I swallow sand into my stomach. I eat sand because it can help me grind food and promote digestion. How about I'm not strong and smart enough?

Well, after listening to my self-report, do you want to be friends with me?

Article 4: ostrich's self-reported composition

It is said that it is a flightless bird. It is very tall and has long legs. It runs so fast in the desert that even a fast horse can hardly catch up with it. "Have you guessed what animal it is? Yes, it is-ostrich.

The ostrich head is small and delicate, wide and flat, and the neck is slender and flexible. The exposed head, neck and legs are usually pink, which is very beautiful. The beak is straight and short, sharp and round; Has charming eyes and inherits the characteristics of birds. Ostriches have good eyesight and can see tiny bugs. They also have very dark eyelashes. I'm telling you, it's against the wind and sand.

Ostrich is a famous player in the competition. Its fastest speed is about 70 kilometers per hour, and it can fly three times when jumping. 5 meters, one step can span 8 meters. Why is it so powerful? It turns out that their hind limbs are very thick, with only two toes, which is different from other birds. They are few in number among birds, so they are listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora.

They have a wide range of nutrients, and grass leaves, seeds and fruits are their favorite. Larvae and small mammals are also good food for ostriches. They are really omnivores. Ostriches eat some grains of sand when they eat food, because their digestion ability is extremely poor. Eating some sand grains can help grind food and promote digestion.

Ostrich is our good friend, we should protect it, and don't see them in the zoo after many years!

"It is said that it is a bird, but it can't fly. It has a small head and long legs. It runs very fast in the desert, and it is difficult for even a fast horse to catch up. " Guess who this is? Haha, this is me-ostrich.

I am the biggest bird in the world! Compared with my huge body, my head is too small, wide and flat, and naked! The neck is long and flexible, and can be compared with giraffes! However, if someone doesn't see my head, they think I'm a brown snake! My hind legs are thick, and at the same time, we are the only birds with two toes in the world!

Look, my big wings, ready to take off ... OK! I admit that I can't fly. Although our ancestors had it, with the passage of time, our flying ability deteriorated!

We like to eat everything, but we mainly eat grass, leaves and seeds ... when we eat, we always like to eat some sand. You must be surprised to hear that. Let me help you explain! Because we ostriches have poor digestive ability, eating some sand can promote digestion, but it doesn't hurt the spleen and stomach. How's it going? We are smart!

In the breeding season, females lay one egg every two days, and as many as 10~20 eggs are laid in a few days. Males hatch eggs at night and females hatch eggs during the day.

Because of our poor reproductive ability, there are many food thieves who steal our eggs, such as Egyptian vultures, hyenas, wolves and so on. They are disgusting, so only 10% of our eggs will hatch. So, I am still a lucky guy!

Now, our number has decreased sharply, and we have been included in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. I am here to make a loud appeal: "Help us, human beings!" "

"It is said that birds can't fly, their heads are small and tall, and they run fast in the desert, even the fast horses can't catch up." Do you know who it is? Haha, yes, this is me, the protagonist of today-ostrich.

My head is small, wide and flat, and my neck is long and very flexible. My head, neck and legs are usually light pink. My beak is straight and short, my tip is flat and round, my legs are big, and my eyesight is the best among birds! My hind legs are thick, with only two toes. Unlike other birds, which have three or four toes, I have the least number of toes among birds! Seeing this, you must think I can't move. Actually, on the contrary, I can jump and fly 2. 5 meters, one step can span 8 meters. What makes me most proud is that my speed exceeds 70 kilometers per hour, which can rival your human car! Speaking of which, I'm starting to be narcissistic!

Once, when I was trying to fly, I tripped over a dog and bit the mud. I still remember that scene clearly. It turns out that my wings can't fly! Alas, compared with other birds, I am really ashamed! Later, I learned that my ancestors could fly, but although we kept our big wings, our flying ability gradually deteriorated!

My life is very leisurely. Sometimes I am in a daze under the tree, sometimes I run in the desert, sometimes I walk on the grass with my children ... My favorite foods are snakes, bugs, birds and insects ... We are not picky eaters like other animals!

Well, after listening to my introduction, do you know me better? Do you think I am cute?

Article 7: ostrich's self-report composition

I flapped my wings, took a deep breath, took two long legs and strode forward ... This is me-ostrich.

My neck is thin and long, flexible and soft. I like to hold my little head high like a swan, just like a lady.

I have a hazel beak, straight and short, which sets off my eyes very small. I live in an arid area of Africa. Whenever it is windy, I cover my eyes with black eyelashes. Over time, we will have long eyelashes.

Although I have wide and flat wings, I can't fly. Oh, what a pity! But fortunately, we ostriches have strong long legs, which makes me a runner, much faster than you humans! If you see a big bird running on the grassland in Africa, it's me. I'm not bragging, our jump can fly about 25 meters, one step can span 8 meters, and the sprint speed is over 70 kilometers! In addition, strong legs are also our very important defensive weapons, and can even kill fierce lions and leopards!

Our staple food is grass, leaves and seeds, and sometimes we eat some lizards, small snakes and young birds. When we eat food, we eat some grains of sand. Don't say we are stupid, because our digestion ability is poor, so some sand grains can help us grind food without hurting our spleen and stomach!

Our poor reproductive ability, coupled with the threat of natural enemies, has greatly reduced our number. This really worries us. I really hope that our race can prosper!
