Inquisitive Capuchin monkeys brazenly forage for hidden sources of food.

In the forests of Central and South America, monkey populations are generally declining. But White-faced Capuchin monkeys are apparently doing better than most other species, and scientists are trying to find out why. Welcome to Pulse of the Planets Science Diaries, a glimpse of the world of science from the inside.

Capuchins seem to be adapting well simply because theyre smart. Theyre arguably the smartest of all the monkeys.

Primatologist Tracie McKinney studies Capuchins in the forests of Costa Rica.

The reason theyre smart is that theyre extractive foragers. Extractive foraging means that they specialize on foods that you dont see at first. They open termite mounds and they rob birds nests and they rip off bark to look for the insects underneath. And they open hard nuts and they really can kind of find these things that are hidden in the forest.
And to do that you have to be pretty bright, and so these animals realize that, you know, a trash can can be exploited, or that a new fruit might be something that they could eat. And the fact that theyre so intelligent gives them a little bit more flexibility than other primate species. The Costa Ricans call them Monos Bravos sometimes the brave monkeys or kind of belligerent monkeys. These Capuchins will get into your trash, theyll get in your yard, they threaten people, they shake branches in your face. One day I was sitting on the ground, and four males came and surrounded me. And they made a little ring maybe three feet from me in any direction. And they threatened me and broke sticks and tried to be very, very scary.

Its all in a days work for a primatologist. Well hear more about the monkeys of Costa Rica in future programs. Check out our latest project at kidsciencechallenge.com.
