The nutcrackers of Piauí

June 20, 2012

Working in natural history film-making brings you to some rather remote locations and lets you see some remarkable behaviours. None are more remarkable than the tool use shown in the bearded capuchin, who cracks the hard casing of nuts with specially selected stones. Here in Piauí, in north-eastern Brazil, I worked as an assistant to Christian Baumeister who shot this fascinating behaviour.
