Crazy chimp bangs on glass, makes kid cry

This is the new chimpanzee in the group, the young Kibali. He is getting a lot of attention from the younger females in the group, which gives him more confidence of challenging Jambo for his Alpha male position. As Kibali makes it's presents known, there are a lot of noises and displays of strength. Jambo who he is challenging is sitting quietly on the other end. When Kibali jumps up and down on the ropes with lots of noise and his hair is standing up he jumps to the ground and then suddenly comes swinging towards the huge window and kicks it with his powerful legs. Unfortunately the little girl watching on the other site didn't expect it as he came launching towards her and it made her jump cry. The other kids on the other site were more prepared when he did it again. Looking at Kibali and Jumbo, I'm guessing Kibali is definitely on the way of getting the alpha male role, when not already there. Jambo who suffers from alopecia is sitting quietly on the other end.
