Although the state has national borders, but animals never abide by the national boundaries, for example: in the last century, China listed tigers as pests and attacked, resulting in a part of the Siberian tiger under the pressure of survival, crossing the national border to russia to live; and now China pays attention to environmental protection, the wild ecology is gradually restored, a part of the Siberian tiger has moved back to China, and now the number of wild Siberian tigers around China's border is increasing.
So the question is, since animals do not abide by national boundaries, will The giant panda, a unique creature in China, cross the national border and go to the surrounding countries?
Although many animals migrate to other countries during their migration, giant pandas do not, because they are too picky.
At present, there are two kinds of giant pandas in China, one is a giant panda living in Shaanxi, and the other is a giant panda living in the Qinling area, they have been separated as early as 300,000, although it looks similar, but there are some differences. Among them, the Head of the Qinling Giant Panda is longer and longer, and it looks more like a bear.
The Shaanxi giant panda has the shortest round head and looks more like a cat.
From the quantitative point of view, the number of Giant Pandas in Qinling is relatively large, so the giant pandas we see are almost all Qinling Giant Pandas. Whether it is the Qinling giant panda or the Shaanxi giant panda, they all live in the hinterland of China, which is very far from the border line and it is impossible to migrate to other countries on their own.
In addition, giant pandas are a very lazy animal, which is mainly determined by their intestines. We know that giant pandas are originally carnivores, so their stomachs secrete high-intensity stomach acid, which kills microorganisms in food, thus avoiding infection because of microorganisms carried in food.
But when the pandas switched to vegetarianism, the strong stomach acid brought them trouble. It should be known that plants are rich in fiber, and fiber can hardly be digested by the stomach, which is excreted by organisms, resulting in a lot of energy waste. Herbivores can obtain nutrients from plants because their stomach acid strength is weak, microorganisms can survive in animals, and these microorganisms can help them ferment the hard-to-break down cellulose in plants, and the decomposed products can be absorbed by the stomach.
Since giant pandas can't get enough nutrients from plants, they have to spend a lot of time eating in order to survive, and spend all their time sleeping when they don't eat, so as not to waste energy.
Giant pandas' food is widely available locally and does not change seasonally, so they do not need to migrate for long periods of time to forage for food. And they are larger, and now they live in a place where large predators threaten them, and they do not have to avoid predators and travel from place to place, so they will try to stay in the local area and will not migrate to other countries.
Although giant pandas will not migrate to neighboring countries on their own, if the number of local giant pandas is too large, and the energy produced locally cannot meet the survival needs of giant pandas, the giant pandas will also spread through radial forms, then will China's giant pandas run to neighboring countries?
In fact, the probability of this happening is very low. Giant pandas are actually animals with a very slow reproductive rate, and some experts say that if the efforts and resources to protect giant pandas are invested in protecting other animals, then other endangered animals have long been out of danger of extinction, rather than being vulnerable creatures like giant pandas.
Giant pandas breed very slowly, they only have estrus once a year, and before estrus they have to learn to mate through live observation, if they do not learn successfully, it may cause conception failure, so some zoos will help the giant pandas learn by playing videos.
The estrus period of giant pandas is very short, only a short period of 2-3 days. Before the estrus period comes, they mark their scent on the trunk, and when they smell it, they rush to mate with them. However, if the number of antelopes in the area where the giant pandas are active is large, it may affect their mating, because the antelopes will rub the trunk of the tree, causing the odor they leave behind to be destroyed, making it impossible for the other party to find itself.
The reproduction rate of giant pandas is also very slow, with an average of 1 per litter, and the giant panda cubs live with their mothers for nearly two years. Pandas with children do not go into heat until the children grow up and leave themselves.
In addition, giant pandas are also very picky eaters, although they are herbivores, they eat almost only bamboo, and only eat 32 types of bamboo. These bamboos do not necessarily exist around our borders, so it is almost impossible for them to migrate to other countries on their own.
For animals, their survival is inseparable from a specific environment and climate, and in different parts of the earth, the climate and environment are also very different, and these are natural barriers, which can make animals with less adaptability be "blocked" in a specific environment, such as giant pandas.
If they migrate to neighboring countries on their own, we may not be able to come back, after all, this is the choice of animals. But by the time the giant pandas have migrated to neighboring countries, they may have been numerous enough to be seen everywhere.
