When I was in college, I read that vervet monkeys have three different alarm calls to warn each other of eagles, snakes, and leopards. Now that I know these animals well, I can say for certain that everything else in their communicative arsenal means, roughly, "You go over there and do something adorable while I sneak up behind the people and grab that bag of nuts."
This monkey might look like it's just hanging out on a post. But I was cooking dinner when I took this picture, and oddly enough, the monkey was one post closer to me every time I turned around.
Eating leaves? Uh-uh. This one has an eye on my bread.
I'm afraid my bread didn't survive its attentions.
It wasn't a fair contest. There were about two dozen of them and only one of me.
