Why do bats like to live in groups? What kind of environment do bats like to nest

Bats prefer to live in groups, with a maximum of 3,000 per square metre in their nests. The reason why they live together is still a mystery. Spanish scientists point out that it was initially thought that bats huddled together could raise the temperature of the habitat, but studies have shown that this is not the main reason.

Later, scientists found that bats that live in groups weigh more than scattered bats on average after hibernation, because some malnourished bats share food with healthy bats when they live in groups. As for the large number of small bats that live in groups, when their mothers go out to hunt, these swells come together to protect each other from predator attacks. It is reported that bats can live up to 30 years.

Female bats do not give birth until they reach maturity at the age of 6-7 years. When mature, they usually give birth to one cub per year. Bats prefer to live in groups, with a maximum of 3,000 per square metre in their nests.

When mature, they usually give birth to one cub per year. Boisterous. Bat animals have a wide range of diets, some species like nectar, fruits, others like to eat fish, frogs, insects, suck animal blood, and even eat other bats.

In general, large bats generally feed on fruits or nectar, while most small bats mainly prey on insects. <>

Bats prefer cold, dark, damp environments to build their nests.

Because bats have extremely poor eyesight, they can basically be considered blind. However, the eyes of bats can sense light and are very sensitive, so they cannot stand it in normal daylight daylight. So they have to find a dark and narrow place to rest during the day and wait until night before flying out.

Bats:

Bat (scientific name: chiroptera) is a group of animals belonging to the phylum Chordates, a class of mammals, and is the only mammal 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 grams, with a wingspan of 16 cm; Some flying foxes can weigh more than kilograms and have a wingspan of up to meters.

Bats are light-boned, have a high degree of healing of the skull, well-developed shoulder girdles, and have keel-like protrusions on the sternum. Degeneration of the tibia and fibula of the hind limbs. The ear shell is well developed, often with a well-developed tragus or 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, while their sense of hearing is unusually developed.

At night or in very dark environments, they are able to fly freely and catch food with unerring accuracy. 70% of bat species feed mainly on insects and other arthropods; The rest of the species feed mainly on fruits, nectar, and pollen; Some tropical species are carnivorous, and there are 3 species of vampire bats that feed on blood. It is found everywhere on Earth except the Arctic and Antarctic and some oceanic islands.

Shine a bat with a strong light. Bats are creatures that rest during the day and come out at night. They like the dark and are afraid of light, so it's best to use lights to drive them away.

Keep the exit passage for the bats clear so they can get out. Therefore, the proposed installation of one-way movable doors and tubes is not feasible.

Use electronics with light waves. Bats can use ultrasound, so they are sensitive to light waves. Some products with light waves can be used to repel them.

Some common insecticides in the home can be used. Bats are mammals.

Like humans, they will be uncomfortable with pesticides, but they are not life-threatening.

Habits. The body temperature of bats varies greatly, up to 56 (by some large caruvore bats.

Due to their different physiological and behavioral characteristics, the body temperature is relatively constant, and the vast majority of small insectivorous bats are typical of heterotherms.

It has been observed that bats living in temperate zones spend much more time inactive than active in their lives, sleeping almost all day and part of the night in summer, and some species when the weather is cold, like birds, carry out long-distance seasonal migrations to the south to spend the winter, and those that remain in place enter a long period of hibernation during the harsh winter.

According to incomplete statistics, inhabited in Leningrad.

The nearby big-eared bat and the northern brown bat spend only 1 15 1 20 of their active time in their lifetime and sleep the rest of the time (Kugakin, 1959). When the ambient temperature reaches 16 28, the bat is in a deep sleep state, and the physiological function of the sleeping bat slows down and the metabolism decreases. Due to low metabolic consumption, some bats have a longer lifespan.

Having bats in your home indicates that there are areas in your home that are suitable for bats to survive. Scientists have found that bats carry a virus similar to H5N1 and have a high mutation rate. So, try not to be bitten by it.

You can call 119 for help to keep the bats away, they have special protective equipment. Then turn on a light at the bat gathering place, and the bats are afraid of light, and they will not come later. (Acted in "Into Science").
