The coldest few days can be regarded as the past, is this the most common situation that everyone encounters in these two days?
But fortunately, we also have thick clothes, heating and quilts. If the animals do not have nests, they can only rely on a body of righteousness to resist.
In the primary school textbook, we learned a text called "Cold Trumpet Bird", unlike the industrious magpie, the cold trumpet bird only cares about playing on warm days, and then when the cold wind blows, we can only shrink our necks and shout: "Dora, dora, the cold wind freezes me, tomorrow I will build a nest." ”
So what exactly is this cold trumpet bird? Other birds do not make nests as they are, but they still do it. For example, spotted dove, throw a few branches to mean.
There seem to be very few birds like the cold trumpet bird, which is completely unsupported.
In fact, this "cold trumpet bird" is not a bird at all, but a mammal, called a weasel. This one that does not fit in also belongs to people's stereotypical prejudices against it.
Squirrel belongs to the rodent order, squirrel family, squirrel genus, there are 16 species distributed in China, we often say that the cold trumpet bird mainly refers to the compound tooth shrew (scientific name: trogopterus xanthipes),
Also common are large red and white squirrels with large heads. Beijing Zoo also has oh.
Their main characteristic is that they can fly. This flight is not flying like a bird flapping its wings, but gliding.
Wingsuit gliding is a device invented to imitate the form of the weasel, but the equipment of the weasel is more reasonable, and their tails can also grasp the direction when gliding.
Squirrels generally live at high altitudes, at least five meters above the ground. So why live in such a high place? Quite simply, if you want to take off, you have to have a certain height.
When I was a child, I watched the movie "Tiger's Mouth Escape" and was impressed by the glider inside, but the weasel did not need to take off for such a long time, they could fly as long as they stepped off the "jumping platform" on their hind legs.
Just because it can fly, in Xunzi, the weasel has become a negative model again. "Xunzi. There is such a sentence in the "Persuasion": The snake flies without feet, and the weasel is poor in five skills. Meaning: the snake has no feet but can fly, and the weasel has five skills but is not proficient. In this way, we urge everyone to study to be single-minded.
But as a weasel, there is no harm in being more knowledgeable, at least it improves its convenience of travel and its ability to escape in times of danger.
Squirrels generally live in tree holes or stone crevices, but unlike laziness in elementary school textbooks, they are very diligent in creating their own small homes.
The nest is covered with hay, neat and dry, and in winter they will block the entrance to the house with branches and hay to ensure the temperature of the nest. So the home of the weasel is very comfortable and livable.
They are similar to squirrels, basically vegetarian, cypress seeds, branches, leaves and pine seeds, branches, leaves and nuts such as pecans and almonds. Occasionally, insects and molluscs are eaten.
They also have a good habit, that is, fixed-point toilets. The range of the squirrel is generally within one kilometer near the home, and the excretion is also in a fixed place, and the drug collector will collect their feces and dried urine, which is a well-known Chinese medicine: Wuling Fat.
The quality of the weasel's food and the five spirit fat is also related, if its food fat content is high, then the five spirit fat is full of oil, the medicinal effect is good, if they eat no oil and water, then the five spirit fat is dry and dim, the medicinal effect is poor.
If their toilets are better waterproof, say on a stone slab, then urine and feces can also form more potent lumps of lipid.
The "Compendium of Materia Medica" records: The five spirits are sweet, warm and non-toxic. Evil ginseng, damage.
"Indications" of the heart of the cold, children's five chancres, epidemic prevention, treatment of intestinal wind, tongli qi pulse, women's blood closure.
Modern analytical methods have found that Wuling Lipids are rich in tetradecanocarbilic acid, linoleic acid and palmitic acid, which have a good effect on reducing cholesterol in the blood, and contain cedar alcohol and chlorophyll alcohol, which has high anti-cancer activity. At the same time, many components in the five spirit fats also have anti-inflammatory and bactericidal effects. As for which ingredients can be hemostasis and hemostasis, further research remains to be done.
Squirrels generally lie out at night, and when they are active, they will make a call of "many rattles, more rattles", and they can fly and bark, so they are divided into birds by Grandpa Li Shizhen. But we now know that this was a beautiful misunderstanding.
The weasel is a quiet animal that generally lives alone and only meets each other during the breeding season. Males and females chase each other for one to four days before entering the mating process. Therefore, it is not easy for male rats to catch up with female rats.
Mice are born 70-90 days after mating, each litter is only 1-3, and the lactation period is generally 100 to 120 days, sometimes up to 150 days. Mice open their eyes for a month, grow hair on their bodies for forty days, and gradually can leave the nest for activity.
Compared with other rodents, the squirrel can be regarded as a model of family planning. So the compound-toothed shrew was included in the IUCN's 2016 Red List of Threatened Species ver3.1--Near Threatened (NT)
The red and white shrew is listed on the IUCN Red List of Threatened Species in 2013 ver3.1 - Low Risk (lc).
They are also "three haves" animals. A license is required if it is to be bred.
The popular pet honey marsapper is not a shrew, it belongs to the order Marsupialidae, The Family Of Marsupialidae, and the genus Marsum. Its resemblance to the squirrel belongs to convergent evolution under the same arboreal conditions.
Tip: Convergent evolution refers to the phenotypic similarity of different species due to adaptation to similar environments during evolution.
brief summary
The weasel is a magical little animal that doesn't just exist in the article, but also lives happily in the forest. Have time to check it out.
