All species of capuchin tend to have a rather similar diet in broad terms; they are omnivores, eating fruits and small invertebrates, small vertebrates and birds' eggs, which they forage at all levels of the forest, frequently descending to the forest floor. In northern Colombia during the dry season when there are few fruits to be found, white-fronted capuchins spend more than half their time on the ground, searching for and capturing small prey. They are extremely good at manipulating objects, and spend a great deal of time examining dry leaves from which they collect invertebrates (for example small beetles and ants' eggs) from rolled up leaves. They hunt frogs and drink the water which accumulates in the spaces between the bracteoles of the common plant "Phenakospermum guianense", where the frogs hide. Hunting amphibians seems to be a cultural phenomenon which the members of each group learn. "P. guianense" is commonly present in large, dense stands in some types of forest.
