That Chimpanzees are not the dumbest animals on earth has been proven with this movie. The animals of the Kingly Burger’s Zoo were filmed with a drone, only one chimpanzee decided that he did not wanted to be recorded.
He took down the Drone with a stick and his fellow Chimpanzee mates made sure that they would investigate the drone. The picked the drone up, tossed it around and then left it to “drone”.
The chimpanzee which hit the Drone was high up in a tree, and he was not served by the strange object in his residence. It only took him one hit to take down the Drone.
