The incident occurred while chimpanzees were being filmed at Royal Burgers’ zoo, in the Netherlands, in April.
Several of the chimps reacted by grabbing willow twigs and climbing a scaffold where the drone was hovering. When the remote controlled craft zoomed in on two of the animals, one of them, a female called Tushi, decided enough was enough. She made two long sweeps with her stick, the second of which struck the drone and downed it.
