https://news.slashdot.org/story/16/11/19/2258252/commercial-mining-drones-ke... The world's seventh-biggest gold producer has lost more than nine drones because of eagle attacks. "People couldn't believe I was able to get such a good photo of an eagle airborne," complained surveyor Rick Steven at a conference sponsored by the Australasian Institute of Mining and Metallurgy. "But I didn't... Another eagle took that photo... I was getting attacked by two eagles simultaneously." The specially-constructed drones carry a $10,000 camera for high-resolution photos and equipment that produces high-detail contour maps of potential mining areas, and so far the company estimates they've lost more than $100,000 worth of technology to eagle attacks. They've tried camouflage -- including disguising the drones as another eagle -- but unfortunately, according to Stevens, the eagle is the "natural enemy" of the drone. One drone's video is interrupted by the sudden appearance of an eagle, followed almost immediately by footage from the ground by a sideways drone camera. That video -- included in the article -- ends with a reminder that "Eagle attacks on drones have been documented across the world, to the point where some European police forces are now training them to take down unauthorized aircraft." http://www.abc.net.au/news/2016-11-17/wedge-tailed-eagles-bring-down-drones-... https://yro.slashdot.org/story/16/02/01/1919257/dutch-police-train-bald-eagl...
