Also, being a Filmmaker myself, I know that documentary filmmakers often use very expensive telephoto lenses to get up close video of the lions and snakes, because there's no way they are going to safely get close enough with a regular Lens without getting eaten. Also if I ever see a bird of prey anywhere in the sky while I am flying, I immediately get the drone far from the birds, and land as soon as possible. I don't take any chances with those unpredictable creatures. I am not into saving the animals, I think hunting is fine, but it is not polite to taunt and scare the hawk with the flying weedeater. I understand the OP didn't know that the hawk lived in the tree, but the first glimpse should have been a sign that he needed to land FAST! the fact that there were 3 attacks tells me that there may have been a desire to taunt the bird, not get away. Hey, I know the temptation, I once taunted some kids down the street with my drone. They were shooting at the drone with bb guns, so I flew up to 400 feet and started to fly circles around them. I realised soon after starting the first circle that I was being stupid and letting my anger get the better of me. We need to be kind and polite to everyone and everything, or we give all drone Pilots a bad name.
