Liu Wei looked at the barrage and said: "Brothers, don't be nervous, I don't have any hallucinations, I hope you will come out of the myths and stories now, we are now conducting a popular science program."

The reason why I cover my mouth and nose is because the red fox uses its top-secret weapon, the bar gland, and when it is pursued by the enemy or encounters other dangers, the red fox's bar gland will secrete a foul smell, which is what we often call the fox odor!"

", the fox stinks, it's disgusting!"

"I suddenly thought of my high school tablemates, and every day I felt like I was living in purgatory!"

"I forgot to tell you, I also have a fox smell, hahahaha!"

"Really Jill is disgusting!"

"Ah Wei, how does it taste?

Liu Wei shook his head, "The stench is unpleasant, suffocating!"

Turning around to shoot Chubby, he shouted, "Chubby come up!"

"Hmm~" Chubby snorted and shook his head vigorously, it refused the taste.

The live broadcast room couldn't stop laughing.

"Brothers, the reason why Chubby didn't catch up with the grave must be that he can't bear the smell released by the red fox!"

The red fox stood at the head of the grave, and it tilted its neck to observe Liu Wei.

It didn't expect that its secret weapon would not have a strong lethal effect on Liu Wei, and this gloomy place did not scare Liu Wei away.

The red fox stared at Liu Wei's footsteps, ready to slip away at any moment.

Liu Wei had just walked to the triangular tombstone and was about to go around and climb up to the grave to catch the red fox.

Swift and quick to jump from the grave, the red fox is a canine with a strong jumping ability, its fluffy tail can balance its body in mid-air, and land smoothly.

Liu Wei turned his head: "Fatty, chase!"

"Wang~" Chubby stood in place and shouted, not daring to move, it was too smelly.

Liu Wei had no choice but to follow by himself.

Sure enough, as he had judged, he found the red fox's burrow in the bushes to the right of the graveyard.

Liu Wei was glad that it did not drill a grave hole, and he knew in his heart that he could not do such an unreasonable thing as digging people's graves.

Liu Wei decided to block the entrance of the cave, not believing that it would not come out, "Brothers, we will guard here tonight, I don't believe it will not come out, the red fox's cave is generally dug deep, and it will not dig many exits like the Chinese alligators and pig badgers that we have popularized." ”

"You see," Liu Wei pointed to the dirt at the entrance of the cave, "the soil at the entrance of the cave has traces of renovation, and it is preparing to renovate its own cave for the winter, so we can be sure that this is the cave where it usually lives."

If my reasoning is correct, when Chubby found it, it probably came out looking for food.

Do you remember, it didn't run away immediately after it found out that Chubby and I were there, and it didn't leave until I gave the order and Chubby chased after him.

Since we met brown bears injured by hunters in this pine forest, it means that there is an environment that can withstand large predators, and animals like red foxes do not want to meet them during the day, so it is the best time to come out at night to find food, and I said that its eyes are very suitable for nocturnal activities, and the red fox, like lions and leopards, has 'killing behavior' when hunting, so I deduce that it is hungry now.

The fox is cunning, I am sure it will be clever to find a way to slip out of the hole, we wait patiently!"

The audience listened carefully to Liu Wei's analysis.

I admire his logical reasoning ability.

These inferences are based on a good knowledge of animals.

"Ah Wei, the criminal police team needs you!"

"It's fun!"

"Red Fox: P, the smell of the fox can't kill you, the wolf is gone!"

"Ah Wei, what is the act of killing?"

Liu Wei summoned a chubby sound, and chubby came around from under the graveyard, and it couldn't stand the smell of foxes left at the edge of the graveyard.

"Chubby, stop me!" Liu Wei ordered.

Chubby began to dig the soil at the entrance of the hole with his two forefeet, it seemed that he had to catch the red fox out, it dug a few times, lay down at the mouth of the hole, stuck its head in to take a look, and then turned back to Liu Wei and called twice.

Liu Wei understood what it meant, and Chubby wanted to say: Master, it's inside!

"Okay, fatty, don't plan, it's very deep, save your strength, you just hold the hole. ”

After instructing the matter, Liu Wei turned back to the live broadcast room and said, "Just now, a brother played a barrage and asked what the 'killing behavior' is?

Carnivores like to tease prey that can no longer escape during predation, and often kill all the prey they can catch and never release them, which we call "killing" behavior.

According to surveys, lions are able to kill more cattle, sheep and donkeys than leopards, far more than they eat.

A leopard is able to kill 17 goats at once, place the carcasses neatly there, and walk away.

A few hungry wolves can kill hundreds of baby reindeer at a time, and a single polar bear can kill 21 narwhals in the Arctic Ocean in a row.

To put it more bluntly, some ferocious carnivores are able to kill far more prey than they eat in one fell swoop, which is the "killing" behavior of animals.

Even if it can't eat it, if it sees it, it will kill it.

The most obvious manifestation of the "killing behavior" is the red fox, a Dutch animal behaviorist, who once observed a red fox jumping into the chicken coop at night, and in about 10 minutes, killed all 12 chicks in the chicken coop, and finally took only one and abandoned one dead chicken.

There are different opinions in zoology as to why these ferocious animals have 'killing behavior': some zoologists believe that "killing" is the cruel and murderous nature of ferocious carnivores, not only in terrestrial beasts, but also in marine beasts, such as killer whales that rush into a colony of dolphins or sea lions, and can almost wipe out the opposing army, but only a few are eaten by them.

Other zoologists oppose the view that even ferocious predators kill by chance, and that not every hunt is a killing act, and that this killing behavior may be caused by the startling and fleeing stimulation of the prey when they approach it, and it is not determined by their cruel and murderous nature.

The current general theory in zoological circles is a combination of two views, which means that the killing behavior of animals is caused by two reasons: murderous nature and external stimuli.

I'm sure there will be new discoveries in the future.

The brothers just heard me mention the killing behavior when I analyzed the red fox, because it came out to hunt tonight with a strong purpose, and we didn't find any carcasses or blood stains of other animals on the way we followed it, so I was sure that it hadn't eaten yet, and then deduced that it would find an opportunity to come out!"

The audience in the live broadcast room saw full confidence on his face, as if the red fox was sorry for his analysis if he didn't quietly stay out tonight.

"Ah Wei, your thinking is too terrifying!

"It's not big, it's bloody, I like it!"

"I've gained knowledge, I've learned a little more, I'm happy!"

"After listening to Ah Wei's popular science, I don't have a good impression of the fox for a while!"

Liu Wei said with a smile: "Humans don't have a good impression of animal killing, especially animals like the red fox that like to harm livestock, it leaves a bad impression on the local people." ”
