Capuchin monkeys in Brazil 's Ubajara National Park filmed using stone tools to dig for food.
Researchers split cases into four methods, 'hands-only' digging, 'stone-digging,' 'stick-probing,' and hybrid 'stalk' use.
Capuchins typically don't get much bigger than 22 inches , plus their 17-inch long tails.
The monkeys' success rate hovered at about 83 percent for both 'hands only' and 'stone-stick' cases.
And the monkeys' efforts with stones and sticks separately was just under half .
But the researchers noted that this might have only appeared that way, because their study was not able to determine if the monkeys were specifically resorting to tools for other reasons.
