Ostriches are also birds, why can t they fly?

By definition, birds are bipedal, homeothermic, oviparous, forelimbs that have evolved into wings, and have a hard peck. In terms of physiological characteristics, the skeleton of birds is hollow and highly healed, and the sternum is well developed except for the flat-chested order (that is, a type of bird represented by ostriches), 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 a short digestive system and the use of uric acid for metabolism, ostriches also have these physiological characteristics.

Whether it can fly is indeed not the core criterion for judging birds,3 and birds need to have two basic conditions to fly: one is to have feathered wings, and the other is to be light and lithe.

Although ostriches also have feathers, their wings are completely degenerate, lacking feather hooks, and their feathers are scattered and not strong. More importantly, the ostrich is too large, weighing 150 kilograms and measuring 2 meters in length.

So, their short, small wings can't support such a huge body, and it's impossible to fly. However, although ostriches cannot fly, they have strong legs and can run up to 60 kilometers per hour, which can help them evade incoming enemies. In addition, the ostrich's wings are not useless, they help the ostrich to balance when running, and they can also block the sun and protect the chicks.

There are also many animals that can fly in non-birds, such as mosquitoes and bats. The ostrich is the largest bird in existence, weighing more than 100 kilograms and reaching a height of more than 2 meters, it is indeed difficult to lift such a heavy body into the air, so the large body of the ostrich is a reason that hinders its flight.

The ostrich's flight organs, which are different from other birds, are another reason that prevents it from flying. The flight organs of birds are mainly wings and feathers that are turned into forelimbs, feathers, and the real flight function in the feathers is the flight feathers and tail feathers, the flight feathers are on the wings, and the tail feathers are long on the tail.

Because the ostrich's wings are too small, the ostrich's wings can't support the ostrich to fly, and the ostrich weighs too much.

Because the weight of the ostrich is too heavy, the ostrich's wings are also very small, and there is no way to support its body.

Because the ostriche's wings are very large, very long, and very large, it is impossible to take off.

Ostriches often do not fly easily because they run for a long time and lack the ability to fly. Ostrich is the largest bird in the world, the height of an adult ostrich can reach 2-3 meters, and the weight of a male ostrich can reach 300 catties. It often lives in the savannah, is good at walking, and is very domineering.

First, the characteristics of ostriches.

The ostrich is very large, with a long and curved neck like a snake, a large head on it, and a triangular beak. The main keel of the ostrich is prominent, not relatively developed, so it cannot fly. In addition to this, the ostrich is also the only two-toed bird among the existing birds in the world.

Its hind legs are thick and powerful, suitable for running in the vast grasslands as far as the eye can see.

Second, ostriches are not easy to fly.

The ostrich is a bird whose ancestors were actually able to fly. The reason why it is not easy to fly away today is due to the decline of its ability to fly. The first ostriches lived in the Gobi and the vast grasslands, and their individuals slowly evolved into tall and large, and became more and more adept at running.

When the ostrich blends into the natural environment of running quickly, its ability to fly slowly weakens until it fades. Therefore, the current ostriches have lost the ability to fly.

Three, the spread of ostriches.

Ostriches are now commonly found in the Gobi, savannah, and other regions, such as the subcontinent and the northern part of Africa. The ostrich feeds on the stems, leaves, and fruits of plants, and occasionally eats small insects and small pebbles to help digestion. The ostrich is particularly capable of running, and its final sprint can reach a speed of up to 70 kilometers per minute.

Its thick legs are its own powerful ** equipment, which can withstand the attacks of opponents.

Because ostriches grow faster and are easier to breed, many areas are now able to breed ostriches in captivity. The feathers of the ostrich have a very high economic value, the feathers are beautiful in texture, soft to the touch, and can be used as elegant clothing and decorations. Dear readers, friends.

There are no birds that exist today that can be flown by camels. It is very difficult for huge birds to fly, and it is even more difficult to trust people. If you want to take off from the ground like an airplane, I'm afraid only Aeolus Pterodactyl can do it.

The Aeolian pterosaur became extinct along with the dinosaurs during the Cretaceous-Tertiary extinction event. The largest flying animal on Earth is extinct.

Aeolian Pterodactyl:Quetzalcoatlus is a pterosaur, also known as the Leopard Snake Pterodactyl, which lived in the Late Cretaceous (Campan to Maastricht Stage), about 84 million years ago to 65 million years ago, the Aeolian pterosaur has a wingspan of more than 11 meters, and it is the largest flying animal known to man.

Quetzalcoatlus is a pterosaur that lived in the Late Cretaceous period (Campan to Maastricht) from about 84 million to 65 million years ago, and is the largest known flying animal. The Pterodactylidae are advanced and toothless pterosaurs. The name ** is the Aztec civilization of the Quetzalcoatl, the god of the Quetzalcoatl.

You think too much, this is a plot that only exists on TV.

Because the strength of the ostrich's wings is relatively small, while the ostrich has a large body, it is better at running on land than at flying.

Because the ostrich is too heavy, and the ostrich's wings cannot support the ostrich to fly, and the ostrich is a bird that lives on land.

Because ostriches are used to running for long periods of time and are not used to flying, when they evolved, they lost the ability to fly.
