Nature vs. Machine:This Drone Is No MatchTo This Eagleby Alice HernandezPhoto Source: Wired s“iNnitcostewmoitiiuttfsseatped-dlrdseestsshdetrnrroeocyanet.el”eissntteod A ustralia. Home to the famous Ugg(ly) boots, 101 the multi-talented Hugh Jackman, the gorgeous Miranda Kerr and… this kickass eagle? You heard that right! Not only is this place home to koalas addicted to eating eucalyptus, it is also home to one annoyed (but still awesome) Australian wedge-tailed eagle. It all started when drone operator, Adam Lancaster, was just minding his own business in a woodland in greater Melbourne, flying his drone, when the wild predator appeared. The eagle focused its attention to the drone and disabled it in less than 10 seconds. Lancaster said that the drone needed repairing after the attack while the eagle flew away unscathed. The attack was so fast to the point that you couldn’t even see it coming. Known as the largest bird of prey in Aus- tralia, this predator is very territorial and attacks he- licopters and paragliders as well. Now it adds drones to its must-destroy list since it feels threatened to its presence. These animals are more likely to feel stressed out when a drone is around and tend to lash out on them, destroying these drones like horrible bosses. Clearly, nature is not yet ready to welcome these machines. If people could disguise these drones as non-threatening looking machines, then less innocent drones become in danger from these wild animals.
