The Chimpanzee are the darlings of the zoological community. People laugh at their antics but in a more deep reflection don't they just behave like us?, after all they are our closest relatives in the animal kingdom.
In this panorama you can observe the chimp on the left hand side waving the willow branch, he was the greedy one. As the branches were inserted through the opening on the door he was going backward and forward to pick the branches and put them to one side, after a couple of trips the ones on the right started to pinch the branches that he was trying to keep for himself.
Once the leaves of the branches were stripped and eaten, the Chimps would go to the wall on the far end, next to the metal door and insert the sticks into tiny little holes that have been drilled on the wall by members of the Zoo staff; you could see that the end of the branch was coming out blacker than the rest of the branch, they were laden with juicy ants for them to eat.
So here is a fine example of interacting communities, the Humans observing the Chimps who in turn eat the Ants.
