Watch the real angry bird attack the drone.
TIP: Never fly a drone near birds of prey.
Point to note: That’s Drone Law in the wild.
Otherwise, there’re Drone Laws in the United States.
“Do not fly drones near birds of prey, they clearly attack seeing you as a threat or the right sized dinner. This will cost you money and potentially harm to the bird. This one was fine.. the drone needed some attention before it could fly again. If you see a bird of prey while flying. Land. I have added this to my operating procedure.” Source: http://melbourneaerialvideo.com.au/
