Who is the best security guard animal? If you think it's a dog, you might be wrong. The newest security guard is actually a goose!

Dog: who wants to replace me? | Giphy in May this year, Jiageng College of Xiamen University invited 16 lion-headed geese to work as security guards on campus. The school said that this can not only enrich the species of waterfowl on campus, but also play a role in expelling snakes.

However, a dedicated goose security guard can not only drive snakes, but also complete the perfect guard task.

In Shuikou Town, Longzhou County, Chongzuo City, Guangxi, a group of "goose troops" are carrying out a serious task of standing guard. Because of the border between Longzhou County and Vietnam, in order to avoid illegal entry, people kept 500 geese at the prevention and control points, together with dogs, manpower, cameras and physical barriers, to effectively defend the border.

Why can it achieve the blocking effect? Because the goose is not only fierce, but also very loud.

In 1998, the delivery man Wright was about to enter a building when he was stopped by two big geese. The delivery man obviously did not realize the power of the goose and just wanted to enter the building quickly. In a panic, the goose attacked him ferociously in the face. Wright also broke her arm during the chase. For this reason, Wright received $17000 in compensation that year.

Goose: I'm angry! | another victim of Pixabay is 49-year-old John Needham. When he was riding on the road, some goose parents thought he was going to hurt the goose and directly knocked him off his bike, and the three geese jointly attacked him.

In a Cincinnati Post, someone wrote: in the countryside, geese look majestic and serene. But the next second, they can knock people to the ground, cause fractures or injuries, or become spitting and biting shells.

It does look like a cannonball. | in the history of Giphy, there have been many incidents of "goose hitting people". So when they show aggressiveness, they can often scare off all kinds of attackers. And the other talents they have evolved are necessary for a security guard.

Geese build nests on the ground, which requires them to have excellent eyesight to detect distant predators and detect danger as early as possible. And will also make a loud sound to remind companions, let people pay attention to. Geese also have a strong sense of territory, especially during the breeding season, when someone invades their territory and is violently attacked.

Until now, geese have been used as "security guards" by some chicken farms. Their ferocious attacks can resist weasels, skunks and other animals. Sometimes, people also raise geese as an auxiliary means, because they will sound a loud alarm to remind people that "there is an outsider invading!"

Gah | at night, geese also have a special function: it allows half the brain to sleep while the other half stays awake. This phenomenon is called single hemispheric slow wave sleep (USWS).

Many animals have this function, including seabirds, whales and some sea lions. Birds sometimes fly non-stop for several days, and lack of sleep becomes a big problem. This method can help them get more sleep efficiently. The study found that when they rest, the two hemispheres of the brain switch to rest, even when they are flying. Half of their brains rest, while the other half use their brains to observe the environment and control their wings. In this kind of sleep, not only the two hemispheres of the brain have different levels of activity, but also really "turn a blind eye and close one eye".

The researchers looked at seals in USWS and found that during this sleep, the awake half of the brain contains more cortical acetylcholine, a hormone associated with hemispheric activation.

Looks like he thought the sparrow was wink with you. | Wiki therefore, geese can also maintain a high degree of vigilance at night and detect intruders in time. When other birds run away, aggressive geese can rush up bravely. The tradition of using geese as "security guards" has a long history, and it has been found that geese were domesticated as early as 5,000 or even 16,000 years ago. The story of "Goose Security" first appeared in ancient Roman times.

In addition to geese, there is another unexpected animal that also bears the burden of guard, which is the llama. Llamas are often used as security guards on pastures in the western United States. When they find intruders, they make strange noises, chase them and spit at them. Of course, there is the ultimate trick-strong feet. It is reported that they are likely to kick the attacking hyenas.

Llama security in the sheepfold. | Wiki, however, most of the animals that people use to guard are still dogs. And this is not without reason, a dog trainer said: "can you imagine training a goose to scout and patrol?" by comparison, dogs are relatively simple. "

So if you want an obedient security guard, you have to be a dog? | Image source: Giphy reference:
