Why do bats go back and forth in the same place

There must be insects in that place, and it's catching insects to eat.

The wings of bats evolved from their forelimbs in the process of evolution, and are composed of ** (wing membranes) connected between their slender claws; The snout of bats resembles that of a rodent or a fox. The outer ear protrudes forward, is large, and is very flexible in movement. Bats have short necks, broad thorax and shoulders, well-developed breasts, and slender hips and legs.

With the exception of the wing membrane, bats are covered in hairs all over their bodies and have different shades of gray, brownish-yellow, brown, or black on their backs, while their ventral sides are lighter in color.

A bat is capable of flying like a bird, but it is not a bird, but a mammal. The metacarpal bones and phalanges of the forelimbs of bats are particularly long, and there are thin, soft wing membranes from the ends of the phalanges to the hind limbs and tails. So, bats can fly in the air like birds.

There are claws at the ends, and when they are resting, they use their claws to hook on branches, eaves, stone crevices, etc., and sleep upside down. They are nocturnal and begin to forage at dusk. The colony habitat of bats and the habits of the east, all, in the summer nights, are more common.

Bats are known as "living radars". He has a small impeller on his mouth, and there are very complex ** folds around his nostrils. This is a peculiar ultrasound device.

It emits high-frequency ultrasound waves continuously. When the ultrasound waves hit an obstacle, they reflect back and become an echo, which is picked up by the bat's ears. Based on the echo, bats can determine the direction, identify objects and live obstacles, and capture or avoid mailboxes.

There are many types of bats, as long as they are divided into two categories, one is the large fruit-eating species, and the other is the small insectivores.

Something you don't know about bats.

1 Some bats can fly at speeds of more than 50 kilometers per hour.

2 Some bats can fish, and the Mexican rabbit-lipped bat can catch more than 30 small fish in one night.

3 The wings of the pig-nosed bat are only 14 centimeters, and the wings of the flying fox, which is as large as a puppy, are up to 2 meters wide.

4 Bats can capture and resolve 250 echoes in 1 second. (Note: Sonic round trips are counted as one group at a time.) )

5 Beginning in the fall, bats accumulate a layer of fat in their lower abdomen, and by the time they hibernate they have more than doubled their weight in the summer.

6 A 20-gram insectivorous bat can eat kilograms of insects in a year.

7 A bat colony is made up of 100 bats.

8 Bats have good eyesight and do not deteriorate. It emits sound waves from the mouth that are 20,000 hertz higher, called "ultrasound", which cannot be heard by humans. When the ultrasound hits an obstacle, it bounces back and travels to the bat's sensitive ears.

Bats use their brains to determine whether to eat or flee by judging the appearance of obstacles.

When I was a child, my grandmother told me that when a mouse is hungry and steals oil, it becomes a flying oil rat, and the scientist uncle has found that large bats evolved from small bats, and small bats originated in the early Eocene 50 million years ago, and the evolution of bats on Earth may be related to the rapid warming of the earth 50 million years ago.

What do bats become? The superstition is that "rats steal salt from salt shakers and become 'salt bees'".

In general, bats do not appear alone.

Bats are social animals. Bats have strong flight capabilities and are also natural hosts to a variety of zoonotic viruses, capable of carrying dozens of viruses.

Adapted to their ability to fly and live a nocturnal life, bats also undergo a series of important changes in their physiology. Usually bats have poor vision, but their hearing is unusually developed, and they are able to fly freely and catch food with unmistakable accuracy at night or in very dim environments.

Bat (scientific name: chiroptera) is a phylum of chordates.

A group of mammals that are the only mammals that can truly fly.

In addition to the characteristics of mammals in general, there are a series of morphological characteristics adapted to flight.

The smallest is a mixed bat, weighing only grams, with a wingspan of 16 cm; Some flying foxes.

The weight can exceed kilograms, and the wingspan can reach meters. Bats are light-boned all over the body, with a higher degree of skull healing, well-developed shoulder girdles, and sternum.

It has keel-like protrusions.

Hind limbs tibia, fibula.

Degenerate. The ear shell is well developed, and often has a well-developed tragus.

or to the tragus. There are abundant sensory hairs on the wing membranes, ears, lips, etc. The colors are varied, mostly brown, gray, and black.

Dear Hello I'm glad to answer for you Bats come home because of the smell of home, bats like the smell of fish, the taste of home, there must be something similar. Do a good job of hygiene, no matter how clean the bats are, they are also wild, and they will carry germs. Insect repellent can be used.

Plugging in the insect repellent can drive the bats away because the sound waves characteristic of the insect repellent will drive the bats away, and the bats are generally afraid of this sound wave. Sometimes bats fly in and may have intruded by mistake due to insect predation, because bats rely on ultrasound to find their way. It doesn't fly home for no reason.

However, there are also because of the type of room or home environment, bats will build nests and nests at home, so you should pay attention at this time. When you see a bat flying into your home, don't slap it with your hands or things, as this may cause them to fight back. Bats are more afraid of light and open flames, if bats fly into the home, you can open the doors and windows at night, turn on all the lights in the home, so that the bats will fly to the dark beam outside.

If the bat flies into the home or into the balcony during the day, when the light is not bright enough, you can use a flashlight to irradiate it, and the bat will generally fly away on its own.
