Surprised naturalists who were using a drone to record the action at the Siberian Tiger Park in China’s Heilongjiang province have had their flying camera snatched out of the sky and destroyed by the curious animals. One tiger showed remarkable energy in leaping up to bat the drone to the ground. The tigers tried to eat it. Then it caught fire. Altogether quite a disappointment for the big cats and the drone owner. In 2016, the World Wildlife Fund announced that for the first time in a century the population of tigers in the wild rose, getting a 20 percent boost in numbers since 2010.
