“It’s so fascinating to watch these rascal macaque monkeys trick the squirrels.”
Saw something similar in a documentary series where they were interviewing a former Japanese soldier from the Pacific war. None of his unit had ever been in a jungle before and did not know what was safe and what was dangerous to eat. It was a frightening time for them. They quickly learned that all they had to do was watch what the monkeys ate since if it was safe enough for a monkey to eat, it would probably be safe enough for a human to eat too.
