Why are there bats in the city, and there are no caves in the city for them to hide?

Because bats don't all live in caves, bats will build nests in some of the darker and dirtier parts of the city, mainly in the crevices of buildings and between buildings, and under the eaves. The second is old buildings, culverts, air-raid shelters, etc., and the environment in which they live is mainly selected in places with low sunlight and certain humidity during the day. Bats mainly eat insects, and in the summer they will often fly to people's homes because of catching insects.

Bats are the phylum 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 range of morphological characteristics adapted to flight. The smallest is a mixed bat, weighing only one gram and with a wingspan of 16 cmSome flying foxes can weigh more than kilograms and have a wingspan of up to meters. Bats are light-boned all over the body, have 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.

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 have also undergone 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.

Because there are insects in the sky above the city.

As we all know, the vast majority of bats prey on "insects" and are a huge number of nocturnal insects, which is the case with almost all biological bat species. Mosquitoes, moths and many Coleopteran pests in its food chain are the objects of its prey, which scientists have studied. Under normal circumstances, a bat can eat the equivalent of one-third of its own mass of insects every night, and a 20-gram bat can eat 200 1000 insects a night, so the demand for food is very large.

There are also bats in the city, although there are no caves in the city for them to hide, but the bats can fly, the range of activities is large, some fly from the wild, some fly from the countryside, and some inhabit bridges and caves, under the eaves.

There are several reasons why there are bats in the sky over the city:

1.The abundance of bats may be related to recent climates, such as rainy seasons.

2.Bats are nocturnal and usually appear in groups, so we have a better chance of seeing bats over the city.

3.Bats normally congregate together during the breeding season to seek another mate, and the annual breeding event attracts the natural scene of bats.

The above are the possible reasons why there are bats in the sky over the city, I hope it will help you.

It's normal to have bats over a city. If there are no bats in the sky over the city, then the situation is not normal, it means that there is a problem in the city, the pollution will be very serious, and there will be no insects.

in dark corners and corners or on the edge of cabinets.

If you want to find it, you should pay more attention to these places. Many bats are attracted to mosquitoes before they come into the house. Check the back and left and right sides of the cabinet, just grab it and don't hurt it, they will eat mosquitoes.

A small gap, as long as the head can get in, its body can go in, and fly out at night to feed all kinds of flying and insects, so when the doors and windows are closed, it can drill into the tile gap and enter the room.

In addition, it will be hung upside down on the eaves or in the cracks of the roof, and if it is a building, there is generally no place to hang it, so it will not stay, but will only fly in to eat insects and fly out.

There are precautions for bat handling at home.

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 and turn on all the lights in the home, so that the bats will fly to the darker outdoors on their own.

If the bat flies into the home or balcony during the day, when the light is not bright enough, you can use a flashlight to shine it, and the bat will generally fly away on its own. Guidance: If bats have feces left at home, it is recommended to avoid direct contact with Xiangxiang when handling them to prevent infectious diseases.

1) Bats are active outside all day long, and sleeping on the hook helps blood circulation and restore physical strength.

2) Most of the places where bats live are cold, dark, damp and rocky caves, and it is uncomfortable to sleep on the ground, so they sleep upside down on trees.

3) Because bats have very inflexible feet, they sleep on trees, and in case of danger, they can immediately flap their wings and take off. Supplements: There are some bat caves in the mountains, which are dark and damp, and are sparsely populated all year round and rarely infested by other animals, which is the favorite habitat of bats.

Quietly visit the bat cave, as soon as you enter the cave, you will smell a bad smell from the humid and cool air, and then, you will feel that the ground under your feet is very soft, it turns out that these are bat excrement. However, bat droppings can be used as fertilizer, which is actually very helpful for humans.

Whenever the bat wants to rest or sleep, it will hang its whole body upside down with the sharp claws of its hind limbs in a head-down manner, unlike most beasts that lie prone to rest, and this habit is related to its body structure and activity mode.

The bat's forelimbs are degenerate, and the hind limbs are short and connected to the wing membrane, so when it is on the ground, it can neither stand, nor walk, or even spread its wings to fly, but can only crawl slowly, which is very inconvenient. Therefore, it is accustomed to hanging upside down at a high place, and once a dangerous situation occurs, it can immediately spread its wings and fly, and its movement is much more flexible.

Smoke drives.

Bats are known in the animal kingdom as "blind", and their flight is located by sound waves, so if there are bats in the house, they can be driven away by smoke, but not open flames. Similar to the smoke repellent method, the electronic insect repellent also uses the method of sound waves to repel bats, which is clean and effortless.

Although the light does not bite people, and even a little afraid of people, but once frightened in the process of driving away, the bats attack, it is really a disaster, after all, 5% of bats carry rabies virus.

In fact, bats are afraid of light, so you can keep the lights on all the time without considering the power consumption, so that the bats will not come again after a long time.

Open the window to drive away. In fact, this is also through the sound wave method, in fact, the bat can not see, relying on sound wave positioning, after opening the door and window, you can create some hitting sound, but although this method will not make the bat injured, but once the fright is excessive, it is likely to bite back, so unless it is an emergency, it is not recommended.

Clean up the sanitary environment in your home.

Clean up the sanitary dead corners of the home in time, in general, because bats are afraid of people, they are not very likely to go to densely populated residential areas, unless there is something at home that has a special attraction to him, such as the female of the bat has a very special attraction to the male, or whether the bat has been killed at home, there are residual blood stains, the bat is sensitive to bat blood, if there is, it must be cleaned up in time.

The main thing is that there is food that they eat.

Bats belong to mammals, in mammals are the only animals that can really fly, the flight of bats is carried out by wings that are connected to the body, fingertips and tail of a layer of books**, because the bat has poor eyesight, it is by receiving the reflected waves of high-frequency vibration waves it emits to identify the direction and judge the position of surrounding objects. Bats prefer to live in warm places, usually perched in trees, caves or rock walls. Most bats feed on insects, pollen, small animals, and some bats feed on fruits, which are called fruit bats; There is also a vampire bat that likes to suck blood, and this kind of bat can be harmful to humans and animals.

The front and hind limbs of bats are connected, and the forelimbs are epidermal wings, and the hind limbs have claws that allow them to hang upside down on objects such as tree branches. The living habits of bats are to sleep during the day and forage for food at night; In winter, bats go into hibernation.
