Decades ago, did you see swarms of bats flying in the sky on a summer evening? At that time, we often tried to catch bats to play, but I never caught them once.

A group of children each carried a pair of shoes, saw the bat swarm flying, threw shoes into the sky, at this time the bat followed the demon, flew towards the shoe, if lucky, you can really buckle one.

But I don't know when bats are getting fewer and fewer, as if they are extinct, what's going on?

What is a bat?

Bats are a species of mammal, the second largest mammal in the world after rodents, and the only mammal capable of flying, using ultrasound to capture food and navigation.

They are widely distributed around the globe, including tropical, subtropical and temperate regions, but are mainly concentrated in tropical and subtropical regions. The body shape of the bat is flat, consisting of three parts: head, body and tail.

The skull is short and broad, and the joints between it and the lower jaw are very flexible, allowing them to catch prey of different sizes. The bat's wings are wrapped in membranes, not bones, and the movement of these wings is completely controlled by muscles.

Being covered with hair all over the body makes bats very adapted to being nocturnal and also makes their body temperature easy to maintain.

Bats eat a wide range of foods, including fruits, nectar, insects, small fish, frogs, birds, and other bats.

Different species of bats will be distributed in different environments because of different diets, for example, bats in tropical regions often eat fruits and nectar as their main food, while bats in temperate regions use insects as their main food.

Bat breeding usually occurs in summer or autumn, when males attract females by making high-frequency sounds.

After mating, the female bat becomes pregnant and places the cub on her own until the cub is able to live independently. Bats usually live in groups, so during the breeding season they concentrate in one place to give birth and care for their young.

Most bats are nocturnal, they are nocturnal and choose to rest in secluded places during the day.

Effects of bats on humans and the environment

Food and medicinal sources: Bats are an important part of many cultures and cuisines. In some countries (such as Vietnam), people eat bats, while in others, people use a component in the urine produced by bats to make a traditional medicine.

Natural control: Bats play an important role in population control of many insects, aquatic organisms and small mammals, thus maintaining ecological balance.

Spreading diseases: Bats can transmit germs and viruses to other organisms, including humans, which is one of the reasons people have a negative image of bats.

Ecological restoration: Bats are an important part of many ecosystems and can help maintain plant growth and ecological restoration.

The reason for the rapid decline in the number of bats today

The impact of human activities on bat populations: With increasing urbanization, human activities have an increasing impact on bat populations.

First, the construction of cities continues to expand, and the habitat of bats is destroyed. Previously dense woods were cut down and grasslands cleared for farmland, leaving bats homeless.

Secondly, buildings in the city also pose a threat to bats, such as the construction of high-rise buildings and inappropriate exterior wall decoration materials, which will affect the survival of bats.

In addition, noise and light pollution in cities can also disturb the normal activities of bats, affecting their reproduction and foraging.

Impact of climate change on bat populations: Climate change is a major challenge facing the world in recent years, and the impact on bat populations cannot be ignored. Climate change has led to problems such as rising temperatures and uneven rainfall, which has changed the ecological environment of bats.

For example, weather extremes such as floods and droughts can affect the food sources and habitats of bats, resulting in a decline in bats.

The impact of disease and alien species on bat populations: Diseases and alien species are also factors contributing to the decline of bat populations. In recent years, white nose syndrome has become an important disease that threatens the population of bats.

The disease is caused by a fungus that can affect the respiratory system of bats, causing many bats to die. In addition, some alien species also pose a threat to bats, such as animals that prey on bats and pests that come with boats, which will affect the survival of bats.
