Re: Sounds like nonsense to me
Birds get out of the way if they know you're there, not compete for airspace. I don't know the spec of the copter in question, but 500g sounds quite lightweight to have any kind of range or be able to carry any camera worth using. Either way, I'm not sure I'd want one hitting the wing tip of my helicopter as I'm focusing on delivering a payload at a very specific location, by definition over fire, and flying very close to the ground with no reaction margin.
