What time do snakes come out in autumn to find food? What time to hibernate?

When winter arrives and the temperature drops to 7-8, snakes begin to hibernate in caves, tree hollows and rock crevices in high dry areas. During hibernation, there are often dozens or hundreds of snakes of the same or different species in clusters. Why do snakes hibernate en masse?

Because snakes are cold-blooded animals, the temperature in their body varies with the temperature of their environment. In winter, when the outside temperature drops, so does the snake's body temperature. Therefore, snakes adopt hibernation to adapt to the low temperature.

During this period, the snake does not eat or move, and only relies on the consumption of the fat stored in the body before wintering to maintain the minimum needs of life activities. In such a harsh natural environment in winter.

Below, the mortality rate of snakes that are scattered and hibernate.

Up to 1 3 to 1 2. If you hibernate in groups, you can increase the ambient temperature by 1-2 and reduce water loss. This greatly reduces the level of energy expenditure in the body, reduces mortality, and also helps to increase the chances of male and female snakes mating after the sting in the following spring.

Every year in April and May, after the snake stings, it begins to come out of the burrow, the first task is to find a mate to mate, the female snake's ** and the glands at the base of the tail can secrete a unique strong smell to attract the male snake to follow. Snakes are mostly oviparous, and a few are ovoviviparous.

From the beginning of summer to the beginning of winter, snakes feed and reproduce, and the three months of the year are the busiest time for snakes to feed, and the prey is very wide, including all kinds of vertebrates.

Snakes don't chew when they eat, they just swallow their food. The snake's mouth can open wide and swallow food much larger than itself. In the process of life, snakes also have the phenomenon of molting, and they have to shed their skin several times a year. The peel of the molten skin is called on traditional Chinese medicine"Snake molt.

or"Longyi"It has the effect of dispelling rheumatism. There are more than 2 700 species of snakes in the world, of which 1 4 are venomous snakes. The largest snake is the anaconda that lives in South America.

It can be more than 11 meters long.

The hibernation time of snakes varies from region to region. Generally, snakes begin to hibernate as early as autumn, but southern snakes may not hibernate until early December. In the warmer Nanning region of Guangxi, the hibernation period of snakes may be shorter, with only about 10 days of hibernation.

As for the time when snakes come out to find food, generally speaking, during the autumn harvest, due to the abundance of food, a large number of small animals such as voles also become fat and strong. This is a good time for snakes to hunt. So, the snake will come out in search of food at this time.

The above is for reference only, and the hibernation and foraging behavior of snakes need to be analyzed according to factors such as specific regions, climatic conditions, and snake species. Also, please keep a safe distance and do not disturb or frighten the snake.

In autumn, snakes come out at noon to bask in the sun and look for some food by the way. At the end of autumn, the snake begins to hibernate in its burrow.

Autumn usually comes out at 12 2 o'clock to bask in the sun, when to hibernate I don't know, I haven't seen a snake for a long time.

Snakes generally hibernate from November to April, but there are also those that start hibernation in early December and emerge in early March.

Different snake species hibernate at different times, such as in Zhejiang, soldering iron heads.

The hibernation period is from late November to early April of the following year, and the five-step snake.

The hibernation period is from early December to early March. Even for the same snake, the hibernation time varies in different regions due to different temperatures, such as the krait.

In Nanning, Guangxi, the hole began to emerge in early April, while in Hangzhou, Zhejiang, it did not start until early May.

Hibernation conditions. Before hibernation, all kinds of snakes forage for food, eat fat and strong, and only after accumulating sufficient nutrients in the body do they choose to live in a dry and warm cave and enter hibernation.

In order to raise the temperature during hibernation, several, dozens or even hundreds of snakes of the same species or different species gather in a cave to hibernate. Sometimes with their counterparts.

For example, rats, frogs, toads and other animals have the same handle and a hole, which can be described as "friend and foe".

Snakes during hibernation do not come out of their burrows because they are inactive, and generally do not bite. However, if there is a ** occurrence and a sudden increase in the temperature of the surrounding environment, the snake can wake up and get out of the hole in advance, and even hurt people.

Some snakes hide in their burrows during the day and go out at night to forage, drink, bathe, and molt. However, when the weather is particularly humid and muggy, it will also force the hole out. Therefore, it is a sign of rain when the snake comes out of the hole during the day, especially in late autumn and early winter, when the weather is cold, and the big snake comes out of the hole, and it will rain in a day or two.

It is the verification of "the big snake comes out of the hole, the heavy rain is knocking", and "the snake is in the aisle, the rain is coming".

The activity law of snakes is an ectothermic animal, and the body temperature changes with the temperature of the environment, so snakes are active in winter and spring, summer and autumn. The activity temperature of the snake is 10 35, and the activity law of the snake is also different because of its different species, such as cobra and king cobra like to be active during the day, which is called diurnal snakes; For example, the krait, the silver krait, and the chrome iron head like to hail at night, and are called nocturnal snakes; For example, five-step snakes and belly snakes like to move in low light (at night and during rainy days), which are called morning and dusk snakes.
