Are bats birds?

Bats can fly, and some people can't help asking whether bats are birds. In fact, bats are not birds, but the general name of Chiroptera. Chiroptera is the second largest group of mammals after rodents. There are 19 families, 185 genera and 962 species, except for some islands in the polar regions and oceans. Distributed all over the world.

Bats are the only beasts that can really fly. although they do not have feathers and wings like birds, and their flying skills are much worse than birds, their forelimbs are very developed, and their upper arms, forearms, metacarpal bones and phalanges are all very long. and from it a thin and hairy layer of soft and tough skin from the end of the phalanx to the humerus, body side, hind limbs and tail, forming the bat's unique flight organ-winged hand.

Bats use waves to determine whether there are obstacles ahead and to change their flight path. In the past, many people said that bats had poor eyesight, but it was actually a big misunderstanding. Many scientists have pointed out that the eyesight of bats is not poor, different species of bats have different eyesight, and the use of ultrasound by bats has nothing to do with their eyesight.

Although bats have wings and look like birds, they have no feathers and do not lay eggs. They have the characteristics of mammals such as females giving birth to young and breast-feeding. Bats are not birds but mammals.
