It would be interesting how they plan on detecting smaller moving objects like birds, which would be more of a challenge than a helicopter or a construction crane. Perhaps lasers and radar similar to how Google's driverless cars detect potential hazards?

I wonder if detecting them is even really a problem. They move, emit heat, and most are naturally inclined to avoid drones already. I'm really curious about whether birds of prey might start hunting drones.

It's a possibility if the drones are delivering food for Amazon Fresh... That would be so awesome!

More fun will be in optimizing stopping birds going for drones. My little photo quad has been attacked by mobs of both seagulls and crows. Wasp-coloured paint and ultrasound squeakers?
