On the "fakeness" of nature documentaries

I remember watching Winged Migration many years ago and everybody was oohing and ahing about the great photography (early drones, ultralights, etc). There’s a scene at 1:04:00 where there’s a poor birdie who ‘just happens’ to have a broken wing on a beach and is surrounded by crabs. All the sinister music is there but I couldn’t help wondering if it was a drone that collided with him and then suddenly I was wondering how many other birds had had collisions in the making of it. I guess you can’t make omelets without breaking eggs.
