The tufted capuchin (Sapajus apella), also known as brown capuchin, black-capped capuchin, or pin monkey, is a New World primate from South America and the Caribbean islands of Trinidad and Margarita. As traditionally defined, it is one of the most widespread primates in the Neotropics, but it has recently been recommended considering the black-striped, black and golden-bellied capuchins as separate species in a new genus, thereby effectively limiting the tufted capuchin to the Amazon basin and nearby regions. However, the large-headed capuchin (S. a. macrocephalus), previously defined as a distinct species, has been reclassified as a subspecies of the tufted capuchin, expanding its range east to Peru & Ecuador and south to Bolivia.
The tufted capuchin is an omnivorous animal, mostly feeding on fruits and invertebrates, although it sometimes feeds on small vertebrates (e.g. lizards and bird chicks) and other plant parts. It can be found in many different kinds of environment, including moist tropical and subtropical forest, dry forest, and disturbed or secondary forest.
Like other capuchins, it is a social animal, forming groups of 8 to 15 individuals that are led by an alpha or dominant male.
This species lives in the northern Amazon rainforest of the Guyanas, Venezuela and Brazil and to the west of the Rio Negro, as far north as the Orinoco in Venezuela. It is also found in eastern Colombia, Ecuador, Bolivia, Peru, including the upper Andean Magdalena valley in Colombia. An introduced breeding population is well established in the northwestern peninsula of the island of Trinidad in the Republic of Trinidad and Tobago. The subspecies/population on Margarita Island in Venezuela, S. a. margaritae, is considered Critically Endangered by the IUCN Red List. It can be found in a large variety of forest types, mainly in tropical rainforests (up till a height of 2700 m), but also in more open forests.
The distribution overlaps with that of other species of capuchins, such as the white-fronted capuchin (Cebus albifrons).
