鸟类纵火犯？

The country of Australia has a lot of wildfires1. People or lightning2 can start fires. But three kinds of birds， known as “firehawks”（火鹰）， may start fires， too. Fires make small animals come out into the open. The birds wait and catch these animals as they run away from fires.

Native3 Australians have lived in Australia for a long time. They tell a lot of stories about firehawks. People have seen birds picking up burning4 sticks from a fire， then they drop them on a dry place and make a new fire. No one has ever taken a picture of a bird doing this. A team of scientists and Native Australian guides continue to attemp to capture this phenomena.

澳大利亞气候干燥，容易发生野火。火灾原因多为人类活动或闪电。三种被称作“火鹰”的猛禽，也是纵火犯。它们守候在火势边缘，等待从大火中逃窜出的小动物，而后将其一举捕获。

澳洲原住民在这片土地生活了几千年，众多关于“火鹰”的故事流传许久。有人曾目睹它们从火场捡起燃烧的树枝，然后飞去干燥的地方重新点火。目前尚未有人收集到任何猛禽纵火的照片。一批研究人员与原住民向导将组队合作，尝试获取证据。
