Bear with me here.
Nature documentarians are a hardy lot. They have to be able to trapes anywhere, anytime, in any climate, to watch in absolute secrecy the natural behavior, life and death of animals without interfering with them in any way.
The cardinal rule for the nature documentarian is “do not get involved”. Animals behave as animals do, and quite often that means they kill one another. And the watcher must not get involved, must be distant, and watch for the sake of understanding without interfering. If he interferes then he changes the natural evolution of the situation, and the knowledge gained becomes useless.
Here the observation does not change the outcome, and the animals do what the animals do, and quite often they kill one another…
