This cone may also continue around the sides of the head to create a black beard.

[citation needed] The crested capuchin formerly occurred between the Doce and Jequitinhonha rivers, in Espírito Santo, Minas Gerais and Bahia, on the Atlantic coast of Brazil.

However, due to loss of habitat, their current range has been restricted in Bahia, eastern Minas Gerais, south of Rio Jequitinhonha and north of Rio Doce.

[1] The species has a broad diet, including fruits, seeds, and arthropods, as well as frogs or even small mammals.

Other species of robust capuchins that have been studied more, such as the black capuchin, have been documented using stones to open food items such as fruits with hard shells or oysters.

[1][9] No observations have been made specifically on the crested capuchin, but they likely live in linear hierarchies that span both sexes, with the top-ranking male dominating the top-ranking female, similar to other closely related species of capuchin.
