An eagle with a small camera on its back has flown from the top of the world's tallest building, the Burj Khalifa skyscraper in Dubai. Video from the imperial eagle, Darshan, was live-streamed as it swooped 829.8 metres to its trainer on the ground. The organisers, Freedom Conservation, claim it is the highest-ever recorded bird flight from a man-made structure. The event was staged to highlight the plight of the endangered bird of prey. Although the camera weighed only 300g, that still equates to 10% of the bird's weight.
