MALI: Tushi and Raimee, two female chimpanzees at Holland’s Royal Burgers’ Zoo, showed their contempt for drones when they pre-planned an attack on one of the machines as it was going around in their compound.
It seemed that they were quietly watching and waiting for their turn to get a chance with the drone and using a six foot willow, Tushi knocked the offending drone down to the ground.
The drone in April this year, was filming at the zoo in Arnhem. A Dutch television crew wanted to use a drone to film the chimpanzees, but after a practice run, the chimps appeared to prepare for the next fly-past with a bit of unwarranted damage in mind. Some of the chimps grabbed willow branches from the ground, and four of them climbed up scaffolding where the drone was hovering, carrying their sticks or weapons.
While studying footage from the busted drone, researchers focused on Tushi’s facial expression during the attack, NBC News reports. Before and during the strike, she frowned. She showed no signs of fear. This suggests that she quite deliberately and forcefully struck at the drone, rather than fearfully or reflexively.
Many studies have been done regarding the behavior of apes and the similarities they have with human behavior. “The cultural differences from one chimpanzee group to another presumably show us the platform of behavioral skill from which human culture evolved,” says Richard Wrangham, a professor of anthropology at Harvard University. “The behavior of our distant ancestors probably varied in much the same way as chimpanzee behavior does today,” he added.
Chimpanzees have a “make-do attitude”, which they use for using whatever is on hand as tools in this case and this is evident from an article in the journal Primates, published by Springer, Jan van Hooff and Bas Lukkenaar.
