I used to work with small fixed wing drones [1] and had birds of prey remove the battery pack from the aircraft while in flight. I always wondered whether they knew or if they just instinctively went for the "head" of the plane and got lucky that the battery was right there.
There were also reports from customers in Australia where eagles would just shred the drone to pieces almost every flight. Putting big googly eyes stickers on the wings seemed to help to some degree.
