What are the animals that hibernate? What are the animals that spend the winter in the south?

Hibernation (aka'Winter sting') is a state in which an extreme but regulated decline in body temperature, metabolism, and other physiological activities is observed as an adaptation to reduced energy expenditure. When the weather got cold, people began to wear thick clothes, but the animals did not have thick clothes, shoes and socks to wear, so they invented some methods to combat the harsh winter. Some animals sleep by hibernating.

Hibernation can be divided into three stages: onset, deep and out-of-sleep. The process by which the body temperature of the sleeping animal begins to decrease to a steady approach to the ambient temperature, which takes about one to several days. Most of the animals that are going to hibernate know most, so what are the animals that hibernate?

Next, let's find out!

What are hibernating animals?

The most familiar ones are frogs and toads.

Snakes, earthworms, bears, crocodiles, hedgehogs.

Turtles, squirrels, bats, ants, wasps, lizards.

snails, etc. In general, these hibernating animals can be divided into ectotherms and cold-blooded animals. For example, snakes are cold-blooded animals, and when cold weather comes, it cannot maintain its body temperature and can only hibernate. They are animals that hibernate passively. Mammal.

They hibernate to maintain energy if they can't find food, so they actively hibernate.

Generally speaking, most animals have the habit of hibernating, so I'm afraid I can't go into detail for the time being, but they mainly live in temperate and cold zones, and can be divided into several categories. reptiles, such as snakes and lizards, hibernate; amphibians such as frogs hibernate; Fish usually hibernate; molluscs such as snails and shellfish hibernat; Some mammals also hibernate, such as raccoons.

Bears, hedgehogs, etc. In addition, some insects also hibernate.

What are some of the animals that spend the winter in the South?

Generally speaking, because some birds can fly, when there is no food in the north, they will fly to the south to spend the winter, such as swans and red-crowned cranes.

Geese, flamingos.

Swallows, mallards, orioles, egrets, cuckoos, cuckoos, and other animals. These animals usually begin their migration south in October and fly back north in March or April to breed and lay eggs.

Hibernating animals include snakes, frogs, hedgehogs, squirrels, turtles; Animals that fly south for the winter include swans, geese, red-crowned cranes, and flamingos.

There are hundreds of hibernating animals, the most common of which are ground squirrels, hedgehogs, frogs, snakes, bears, snakes, crocodiles, turtles, etc.; Animals that spend the winter in the south include house swallows, swans, red-crowned cranes, swallows, geese, and cuckoos.

Hibernating animals are bears, snakes, squirrels; To the south there are too many animals such as geese, rhinos, hippos.

Animals that spend the winter in the south include house swallows, swans, red-crowned cranes, swallows, geese, and cuckoos.

1. Swallows are beneficial birds of nature, mainly feeding on mosquitoes, flies and other insects, and can eat 250,000 insects in a few months, so people can't hurt it. In the autumn before winter comes, the swallows make their annual long journey—flying in flocks from the north to the far south, where they enjoy the warm sunshine and humid weather, leaving the frost and bitter cold winds of winter to the chickadees, grouse, and ptarmigans, which never fly south for the winter.

2. Wild geese fly back to the north after the spring equinox every year to breed, and fly to the south after the autumn equinox for wintering. Wild geese love, wild geese never live alone, and singular numbers rarely appear in a group of geese. When one dies, the other will commit suicide or die of depression.

3. The swan is a winter migratory bird that likes to live in groups in lakes and swamps, and mainly feeds on aquatic plants. In China, they fly in large groups from the south to the north during the month of each year to lay eggs and breed in the northern border provinces of China.

The female swans lay their eggs in May each year, and then the female hatches her eggs, and the male goose guards her side and does not leave for a moment. After October, they move south in groups. Wintering in warmer climates in the south and recuperating.

4. Red-crowned cranes leave their wintering grounds in late February and early March to move to their breeding grounds in spring, passing through Beidaihe, China from mid-March to the end of March. The time to arrive at the breeding grounds in the Northeast is from the beginning of April to the middle of April, and the autumn begins to leave the breeding grounds in late September and early October to migrate southward, and the time of migration through Beidaihe is from mid-October to mid-November, and a large number of them are in early November.

5. Mallard duck is a migratory bird, which migrates south in autumn and winters in autumn under natural conditions, and often winters in provinces or more south areas in the Yangtze River basin in China. In late spring, it passed through North China to Northeast China, and arrived in Inner Mongolia, Xinjiang and the former Soviet Union.

There are animals that go to the south to spend the winter, and the common ones are swallows and cranesRed-crowned cranes, egrets, such as egretsCattle egretetc., wild ducks, such asMallard, geese, such asWild geese, bar-headed geese, snow geese. In late summer and early autumn, these birds migrate south from their breeding grounds to their winter grounds, and from their winter grounds north to their breeding grounds in spring. These birds, which migrate north and south with the changing seasons, are called migratory birds.

Migratory bird migration

The winter habitat of grassland migratory birds in China is in the warm Indian Ocean.

On the North Shore, until now, the mystery of why birds were able to accurately orient themselves was still an unsolved mystery in biology. When birds begin to migrate is generally affected by the length of daylight, but climatic conditions, wind direction, and wind speed can also affect the migration time.

The length of sunlight will affect the endocrine nature of birds, and when the migration season comes, the behavior of birds becomes restless, which is called migratory anxiety, and if the climate, wind direction and wind speed conditions are suitable, birds will begin to migrate.

The winter habitat of grassland migratory birds in China is on the warm northern shore of the Indian Ocean. Migratory birds migrate because of temperature, food, and plate drift. Scientists have only recently begun to know more about the specific flyway routes and regions, because there are lighter and more practical positioning devices that can be worn by birds.

Migratory birdsSome birds can change their habitat by migrating regularly with the change of seasons in the middle of the year, and these birds are called migratory birds. Migratory birds can be divided into two types: summer migratory birds and winter migratory birds.

The former refers to flying to a certain area in spring and summer to nest and settle down, give birth to children, when the young birds grow up, it is late autumn, they fly to the warmer areas in the south to winter, and fly to this area to breed in the spring of the following year, for this area, this kind of bird is called summer migratory birds.

01 The first animal is the frog, the body temperature of the frog will decrease as the temperature drops, and when winter comes, it will be put into the soil without eating or drinking, that is, hibernating!

02 The second animal is the snake, the body temperature of the snake will also decrease with the drop of the outside temperature, it is a lower animal, the heart does not have two ventricles, and it also needs to hibernate to ensure the temperature.

03 The third animal is the squirrel, the squirrel is actually a warm-blooded animal, not completely cold-blooded, so it still needs to consume some energy to hibernate after stopping eating.

04 The fourth animal is the snail, which secretes a mucus secretion at the shell when it is dormant to prevent the outside from entering the cold temperature.

05The fifth animal is the hedgehog, and the hedgehog is also unable to regulate its own body temperature, and the hibernation time can be as long as 5 months.

1.Frogs: Frogs are amphibians and cold-blooded, their body temperature is affected by the air temperature, and as the temperature gets colder, their body temperature will gradually decrease.

When the temperature drops to a certain level, the frog burrows into the dirt, does not eat or move, and sleeps to escape the cold.

2.Asiatic Black Bears: Black bears hibernate and build nests in tree hollows, burrows and burrows in the ground, under logs or rocks, along river banks, in dark ditches and shallow depressions before winter begins.

And in the fall, eating a lot of food in preparation for hibernation will eat a lot of food to store fat, and spend the whole winter dormant in a hole, not eating still, in a semi-sleepy state.

3.Toads: Toads overwinter in swarms or under moist soil on the ground, and stop eating to maintain a minimum metabolism by storing glucose in the liver.

Wait until the temperature rises to 10-20 the next day, and it will not end hibernation, which is one of the animals that hibernate for the longest time.

4.Lizards: A small number of lizards native to temperate zones can hibernate, can be spread with more sand and gravel and dry grass and dead leaves, and placed in a place with a more stable indoor temperature and a quieter environment.

5.Snakes: Snakes are also animals that need to hibernate and all species of snakes hibernate when the ambient temperature drops below 15. At this temperature, snakes generally begin to hibernate in the fall.

6.Squirrels: Squirrels prepare their food in winter, seal their holes with hay, hold their long fluffy tails for warmth, start hibernation, and wait until the weather is warmer before coming out.
