The tufted capuchin (Sapajus apella) has a bundle of long, hardened hair on the forehead that can be raised as a sort of "wig". Also known as the brown capuchin, black-capped capuchin, or pin monkey, it lives in groups of two to twenty or more animals in northern South American – primarily in Brazil, around the Amazon Basin. It mostly feeds on large quantities of fruits and insects as well as plant matter such as fresh stems, leaves, buds and flowers. It will also hunt smaller animals like frogs, bats and birds and also feed on eggs . Natural enemies of the capuchin are large birds of prey.
