What is the difference between the way bats fly and the way birds fly?

The difference between the flight of bats and birds is mainly the way of flying, bats are mainly based on swooping and gliding with the help of company buoyancy, while bird flight is more a combination of vibrating wings and gliding, and the flight distance is longer and the endurance is longer.

An article published in the latest issue of Nature examines the aerodynamic differences between bat and bird flight.

The article says that both bats and birds fly by flapping their wings, but in different ways, bats gain lift by flapping their wings back and forth.

The team of members from Sweden, Germany and the United States used shrew-shaped long-tongued bats in their trial. They first filled the tunnel with a dense fog with a machine, and then put the bats in it to monitor the movement of particles in the fog as the bats passed, so as to understand the aerodynamics of each flap of the bats' wings.

1. Jeffrey Spading, a professor of aerospace and mechanical engineering at the University of Southern California in the United States, said: "Bats seem to be mainly good at flying agilely and flexibly in complex environments. In general, the flight of bats is characterized by spurts and sharp turns. They are very agile in their movements. ”

Previously, scientists have studied the flight of birds in wind tunnels.

The way bats fly is different from the way birds fly, birds fly mainly by gliding and flapping their wings, and bats mainly fly by flapping and swooping gliding.

Bats use their mouthparts to determine the direction of flight and whether there are obstacles in front of them, while birds use their eyes to fly through vision, one is sound waves and the other is vision, which is the most essential difference.

Bats are not birds, but mammals.

Although the bat has wings connected by the epithelial membrane between the front and rear limbs and the tail, and the sternum and pectoral muscles are well developed, it can spread its wings and fly like a bird, but it is not a bird.

Although bats have the same wings as birds, they do not have the same feathers as birds, and they are not oviparous, they are viviparous, bats are a kind of mammals, and bats still have teeth, but birds do not, so in general, the difference between bats and birds is quite large, which also means that bats are not birds. Bats belong to the group of mammals in the order Pterodactyla and have the ability to fly, and the pterocods are the second largest group of animals, and the first group of animals are rodents.

Bats are not birds, bats do not have the feathers of birds, the way of reproduction is not to lay eggs, birds do not have teeth, but bats have teeth.

If the bat is a bird, it lacks the most important feathers and beak of birds; If bats are beasts.

It just has an extra pair of wings. Therefore, the bat is neither a bird nor a beast, it belongs to the mammals that can fly in the air.

Although bats have wings and sternums connected by the epithelia between the fore and hind limbs and the tail.

It has well-developed pectoral muscles and can spread its wings and fly like a bird, but it is not a bird but a mammal. Because bats have no feathers on their body surface, have teeth in their mouths, and have diaphragms in their bodies to divide their body cavities into thoracic and abdominal cavities, which are the basic characteristics of mammals. What's more, bats reproduce and develop in viviparous lactation, rather than oviparity like birds, a characteristic that suggests that bats are truly mammals.

Birds are usually feathered, oviparous animals with a very high metabolic rate, and the long bones are mostly hollow, so most birds can fly. Birds are made up of reptiles.

Evolutionary has led to more than 9,000 species of birds living in the world, all of which have wings and feathers, including those that have lost their ability to fly (such as ostriches, penguins, etc.). The body is spindle-shaped, the forelimbs are specialized into wings, the body surface has feathers, the body temperature is constant, the musculothoracic is developed, the bones are healed, thin, hollow, and the brain is relatively developed. Having an air bag allows for double breathing, and not having a bladder can reduce body mass.

These physical traits are well adapted to flying. Birds have no teeth but have beaks that can be used to hunt, build nests, and groom their feathers. Birds are good at building nests, and they can build all kinds of nests from the materials they collect.

Ornithischia is taxonomically a subphylum of vertebrates.

under one of the classes. Because its body is covered with feathers, ancient Chinese zoology collectively referred to them as feather insects.

1. At night, bats rely on sound waves to find their way and hunt. They emit sound waves that are inaudible to humans. When this sound wave encounters an object, it returns like an echo, allowing the bat to tell if the object is moving or stationary, and how far away it is.

2. The throat of the bat constantly emits high-frequency screams during flight, and then emits it through the mouth and nose, and when this ultrasonic signal hits any object, it will be reflected back and then transmitted to its unusually large pinna ears.
