For Survival, They Unite in Armies, Various Animals Display Astonishing Wisdom in Confronting Predators
In our blue planet, whether it's humans or animals, we're constantly battling nature, especially in the animal kingdom where it's full of risks and fierce competition, animals often resort to various ingenious strategies for survival, sometimes even astonishing us humans.
However, among all these survival strategies, one is remarkably effective for both humans and other animals – collective action.

American Bison
American Bison gather in groups to evade wolf attacks
In Canada's Five Lake Buffalo National Park, several hundred wild bison reside here. These American bison are animals you don't want to mess with. They're covered in tough, resilient muscles, wrapped in a one-centimeter-thick hide, looking like armored vehicles. They often fight on the ground, but here, these massive creatures are a meal for others, along with these guys, 'Wolves'.
Wolves prey on large herbivores, honed over years of training, they've become the largest and most ferocious wolves in North America. They can often capture large American bison with incredible stamina.A mature bison stands up to 200 centimeters tall, while a wolf is only 80 centimeters, with a bison weighing 1000 kilograms and a wolf weighing only 60 kilograms. Bison can run at a speed of 50 kilometers per hour, while wolves can reach 60 kilometers per hour. If 1 against 1, wolves definitely wouldn't be able to beat bison.
However, wolves don't act alone; they always operate in groups, cooperating with each other, allowing wolves and these huge bison to stand against each other. But bison also adopt collective cooperation. The huge number of cattle makes them more intimidating, and group living can also provide protection to weaker groups. There's always a bull in the herd that serves as a sentinel, while wolves are always watching them, preparing to seize a potential target.
Wolves will target injured, elderly, or sick bison, they'll fixate on such prey, and the resulting confrontation will eventually become a fierce battle. Predators and prey all have their own battle plans. Bison decide to remain stationary. Wolves hope that bison will run away, but bison are stubborn. If they stand their ground, victory is within reach. But wolves are patient, encircling the herd, trying to play a cat-and-mouse game, even if they continue for several days.
In fact, if the bison are startled and flee, the wolves can't control the whole situation. But bison are used to being chased, and they can run at this speed for several hours. Wolves try to take the initiative, isolating the target and firmly locking it down. But bison remain calm, just continuing to run, continuing to unite, and in most cases, bison can escape unscathed. Relying on their huge size and tight group cohesion, bison easily leave these sharp-toothed killers behind.

The bison that were chased
Ostriches gather other ostriches to incubate eggs, a large number of baby ostriches come together to defend against jackals.
Ostriches are the largest birds, unable to fly due to their large size, they were born with the ability to run only. Anyone who disrespects these super legs must be cautious, because they are unarmed, their feet are like axes, sharp and firm. Even if they are confronted by vigilant challengers, they will be torn to shreds, and it's impossible for such a weighty animal to confront – it's a completely impossible opponent 'Jackals'.
Jackals survive by using their brains rather than their strength. They are natural tricksters, able to steal food from even the deadliest predators like lions, so let's take a look at the facts.Ostriches weigh 10 kilograms, while jackals weigh only 8 kilograms, ostriches are 250 centimeters tall, while jackals are only 40 centimeters, ostriches can reach a speed of 70 kilometers per hour, while jackals can reach 60 kilometers per hourAlthough ostriches have a physical advantage, shrewd jackals might use clever tactics, let's see.
The safest approach for jackals is to choose to steal ostrich eggs, which requires no effort. But for jackals, capturing light-as-a-feather chicks and heavy, huge ostriches is a completely different matter.
These ostriches are extremely sensitive, they always understand that they are in a dangerous situation.
The eagle's vision is extremely good, it can detect ostriches within 5 kilometers.
When the eagle swoops down, they will use their 8-centimeter claws to attack the ostrich, as a chance of survival
However, if the ostrich always lowered their head and forage, they can't take care of the eagle, the answer is to assign a sentinel, this is a difficult task, a serious responsibility.
The eagle was waiting for an opportunity.

The eagle kept playing the time game.
The ostrich sentinel is crucial, it cannot be careless, as long as it is standing guard, the other ostriches can relax.
The eagle saw the ostrich sentinel running away, and the eagle seized the opportunity.The eagle failed to hunt, and the jackal retreated, a rare event.
The ostrich sentinel cleared the battlefield, and reversed the relationship between predators and prey.

Cats send out sentries to alert eagles and save their kind.
Now I will introduce the most anxious animals in Africa – meerkats. But they are not cats, they are meerkats, only 30 centimeters tall, with lots of fur, very friendly and distinctive, but are they too sensitive?
These meerkats understand that they are in danger.

The eagle's vision is extremely good, it can detect meerkats within 5 kilometers.
When the eagle swoops down, they will use their 8-centimeter claws to attack the meerkats, as a chance of survival
However, if the meerkats always lowered their head and forage, they can't take care of the eagle, the answer is to assign a sentinel, this is a difficult task, a serious responsibility.

In conclusion, unity is important. It seems that this principle is understood by humans and animals alike, and it's more effective than clever strategies in defeating enemies and gaining a chance of survival.
