Hollowhorn Capiri

The hollowhorn capiri split from its ancestor, the hookjaw capiri. It now has evolved a big, hollow horn, which is used in fights between hollowhorn capiris, and to defend from predators. The horn has become hollow in reason of the weight of it. Now the massive walls of the horn are ca. 10 cm thick. When they see a predator, the hollowhorn capiris will form a circle, with the young in the middle. The big horn is used to scare predators away. When a predator attacks the hollowhorn capiri will try to dodge and hit the predator with its lower jaw horn. The horns at the lower jaw are used to dig out food from the frozen soil. The hollowhorn capiri has strong jaws for chewing wooden food parts. The sail is used for communication between herd members. The hollowhorn capiris travel in herds of 10 to 15 individuals.

In mating time, the bulls will fight for dominance in the herd. To impress the cows, the bull will change colors in his back sail as often as possible. Per oftener a bull can change colors, the higher its mating chance will be. When fighting the bulls bang their heads from the side. Often one of the adversarys will flee. The winner will get more dominant in the herd.
