Want to know why birds fly? Why do birds fly?

Birds can fly for the following reasons:1. Birds fly by wings, not only to have wings but also to have developed muscles in the chest, which can pull the wing bones to carry out strong movement, so that the wings are flapped and the power of flight is generated.

2. Birds flapping their wings can not only make their bodies rise into the air, but also make them move forward and land smoothly.

3. The body of the bird is relatively light, the bones are very slender, and most of the bones are filled with air. Such a skeletal structure provides superior conditions for flight.

The dues are Ye Wei, who has a pair of wings. If you don't have wings, you can't fly.

The reason why birds can fly is that the outside of the bird's body is light and warm feathers. Feathers not only keep warm, but also give the bird a streamlined shape and experience minimal resistance when moving through the air, which is conducive to flight. Fish can swim, and humans can learn this skill.

However, the ability of birds to fly cannot be mastered by humans, and no amount of practice can enable people to fly into the sky on their own.

The origin of the birdSince 1861, Archaeopteryx has been found in the Late Jurassic strata of Germany, about 100 million years ago, with claws on its wings and long tail vertebrae.

Later, it was learned that birds were from reptiles.

Animals evolved. But from the Reptiles.

Which of these evolutionaries has been a hot topic of debate.

It was not until the 90s of the 20th century that a major breakthrough was made in the discovery of a large number of extremely well-preserved small theropod dinosaurs and a large number of ancient bird fossils in the Late Jurassic Rehe biota in western Liaoning Province, China, which is about 100 million years old.

Birds can fly because their wings and chest have well-developed muscles, and the thoracic muscles can pull the wing bones to make powerful movements, thus generating the power to fly.

Birds flap their wings to not only lift their bodies into the air, but also to move them forward and land smoothly.

The internal organs of birds also provide favorable conditions for flight. Birds do not have a rectum to store droppings, nor do they have a bladder to store urine. In this way, when they are flying, they can excrete their feces anytime and anywhere, thus reducing their weight and facilitating their flight.

Habits

Birds eat a variety of foods, including nectar, seeds, insects, fish, carrion, or other birds. Most birds are active during the day, but some birds (such as owls) are active at night or at dusk. Many birds make long migrations in search of the best habitat (e.g. Arctic terns), while others spend most of their time at sea (e.g. albatrosses).

Most birds can fly, and a few flat-chested birds can't, especially those that live on islands, have basically lost the ability to fly. Flightless birds include penguins, ostriches, kiwis (a wingless bird native to New Zealand), and the extinct dodo. When humans or other mammals invade their habitats, these flightless birds are more vulnerable to extinction, such as:

Big puffins, moa in New Zealand, etc.

Every spring and autumn, birds fly in flocks and in the sky, and this seasonal phenomenon of changing habitats in different seasons, either from nesting to wintering grounds, or from wintering grounds back to nesting sites, is called bird migration. Every year, when the earth is rejuvenated, birds begin to carry out a series of activities such as courtship, reproduction, nesting, incubating eggs and brooding.
