Behold! A highly territorial wedge-tailed eagle knocked a drone out of the sky in Australia. This is why drones are illegal to fly in US national parks (and parks right here in Seattle). Clearly this bird collided with the drone on purpose (the bird was okay, btw), but the Audubon Society notes that some collisions aren't intentional and recommends equipping drones with ultraviolet light (which birds can see but humans cannot) to make them more noticeable to our feathered friends.
