The Río Cesar white-fronted capuchin^[1] (Cebus cesarae) is a gracile capuchin monkey native to the Cesar River Valley in northern Colombia.

• It was previously thought to be a subspecies of the white-fronted capuchin (Cebus albifrons).
• Genetic analysis by Jean Boubli in 2012 shows that this Colombian capuchin is more closely related to another Colombian white-faced capuchin (Cebus capucinus) than to Cebus albifrons.
• Some authors consider it a subspecies of the Varied White-fronted Capuchin (Cebus versicolor cesarae).
• The Río Cesar white-fronted capuchin lives in dry semi-deciduous forests, gallery forests, and mangroves.
• Its coat is light in color. Males have a head and body length between 30.8 and 40.7 cm (12.1 and 16.0 in) with a tail length between 41.9 and 49.5 cm (16.5 and 19 in).
• Females have a head and body length of between 35.3 and 38.5 cm (13.9 and 15.2 in) with a tail length of between 46.1 and 50 cm (18.1 and 19.7 in.).

• Like other monkeys of the genus Cebus, the Río Cesar white-fronted capuchin is named after the order of the Friar Capuchins because the crests of these friars closely resemble the coloring of the monkey’s head.
• The group size varies between 15 and 35 members. A dominant male and female usually lead groups.
• Río Cesar white-fronted capuchins are very social and spend a lot of time grooming; however, dominant males and females receive a high proportion of grooming and rarely groom other individuals.
• The small size of white capuchins makes them vulnerable to large predators.
• These capuchins have adopted a loud alarm call that surprises some predators and can warn other group members of the predator’s presence.
