Drones can be a great way for scientists and zoo staff to keep an eye on the animals they study or care for ... but sometimes, the animals have their own plan. When staff at Royal Burgers' Zoo in the Netherlands sent a drone in to record their chimpanzees, one resourceful ape had no trouble showing the electronic intruder just how she felt about it. "She perched high in a tree with a long branch – seemingly very peaceful and happily dozing in the morning sun," the staff said. "Patiently waiting until the drone came just a little too close."
