In the bird kingdom, if the seats are arranged according to the size of the seat, the top seat should be the ostrich.
The ostrich lives in the African savannah and semi-desert, and it is a veritable "big Mac" among birds. You see, the adult ostrich is 2.7 meters tall, 2 meters long, weighs more than 130 kilograms, and even lays eggs that are the largest bird eggs in the world, looking as big as a small watermelon.
Ostriches are not only big, but also funny. A slender snake-like neck supported a small head with a short, flat, triangular mouth made up of several sheaths, a large body, long legs and a long neck, and a pair of large eyes that revealed a alert look.
Ostrich wings have degenerated and can only walk and cannot fly. The ostrich's legs are strong and powerful, the steps are very large, a step is 2 to 3 meters long, when running, a step can step out of 8 meters, the maximum speed can reach 70 kilometers per hour, fast as the wind.
Why do ostriches have the ability to run so fast? This is because ostriches live in deserts, where vegetation is sparse, water is scarce, food is difficult and must travel long distances. At the same time, in the face of enemies, it is difficult to hide in the desert, and only by running fast can you save yourself.
Ostrich legs are long and stout, only two thick forward toes, and is also the only two-toed bird in the world, its outer toes are small, its claws are degenerate, the flesh toes have strong claws, especially developed, and there are thick meat pads at the bottom of the toes, running in the desert, not easy to sink, which create conditions for it to run fast in the desert.
After being domesticated, ostriches are very obedient and are a good "helper" for some African residents. Some Africans are so poor that they can't afford even a donkey, so they have to keep two ostriches, which can be used as mounts when they go out, and can also be used to graze sheep, and when thieves steal sheep, ostriches will rush over and drive the thieves away. #夏日里的清凉时刻 #
