It's been a rough couple of weeks to be a drone
Drones fell from the sky in China and others have been attacked by birds in Australia

As determined opponents of technological progress, we take great pleasure in reporting that the sky itself seems dead set on murdering drones lately.
The first example of this uplifting trend is the story of a raven in Canberra, Australia that was filmed denying air space to a machine delivering coffee about two weeks ago. The raven, no doubt furious that an assemblage of metal would dare to use its skies for something as trivial as transporting a small quantity of coffee, flaps up to the drone and beats the hell out of it for a bit before leaving it alone as a warning.
Though the attack shown above wasn’t successful, The Canberra Times reports that the ravens are learning “how to avoid the drone blades” and are “getting better at [attacking them] by the day.” As a result, one delivery drone company has now had “to suspend flights over the area” and experts are trying to figure out ways for their devices to operate without being pecked to bits by angry birds.
