Black-capped Capuchin

The tufted capuchin (Cebus apella), also known as brown capuchin or black-capped capuchin is a New World primate from South America. 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, thereby effectively limiting the tufted capuchin to the Amazon Basin and nearby regions.
