yesterday evening i bumped into an agouti (= a rodent about the size of a hare, guatussa in local spanish): brazil nut trees rely on them for propagation as they're the only animal capable of gnawing through their rock-hard outer shell, no brazil nuts here but a relative called "olla de mono" (=monkey pot (tree)) -- as they're not always fruiting and only grew occasionally higher up in the jungle i haven't tried them, yet...
