He seems to respect the forest, I wonder how he knows what animals to hunt and how to decide if an animal is rare or not, to protect the populations of creatures, he would have to know how big the groups are? Maybe if he sees a large herd, he knows he can take a small animal from the herd, and the overall population won't be damaged? If he kills too many large animals, the overall herd size will probably decrease? But what if he sees only one animal? How would he know whether he should kill it or not?
