Is it biological nature that large herds of deer can circle?

The phenomenon that large herds of deer can circle is a biological nature and an evolutionary phenomenon of self-protection in the animal kingdom.

Herbivores circle to distract predators from their targets. Imagine a deer as an easy prey. In the process of hunting, a single target will not interfere with the sight of hunting animals, and it is easy to become a victim.

Moreover, the rotation around the circle will make the predators unable to distinguish the animal targets they mainly prey on, and drive the predators to give up with a kind of fatigue war.

Another purpose of a large group of deer in circles is to put the deer in the circle, and the mature deer move in the outer circle, completely shielding and interfering with carnivores, confusing right and wrong, and achieving the purpose of safety.

Animal circles are not an accidental phenomenon, but an evolutionary process and a natural biological nature. Not only among deer, but also among wild cattle and sheep.
