This arboreal primate is slim and agile (2), with an olive-brown coat and black-skinned face (4). The underside is white, and there is white fur on the brow and cheeks (4). The most striking feature of the Malbrouck monkey is the colouration of the male, which has a bright blue scrotal area and an eye-catching red penis. The Malbrouck monkey possesses cheek pouches in which food can be stored for later consumption (4).

Malbrouck monkey biology

Little information is available on this species’ behaviour and ecology, but what is known about the Malbrouck monkey is that it lives in groups of multiple males and multiple females (5). Females of this species typically remain in the group in which they were born, but males disperse upon reaching maturity (6), and will emigrate to another group to find a mate; this is a risky time as females have been known to aggressively attack transferring males (7). The Malbrouck monkey uses impressive vocal and visual signals to communicate information between group members (5).

Breeding is seasonal and controlled by the dominant male of the group, who uses aggression to scare off any lower-ranking males that try to mate with the higher-ranking females (6). Females usually give birth to a single offspring. Allomothering is common in the Malbrouck monkey, whereby older females care for their younger siblings, enabling them to practice valuable mothering skills. Other members of the group are also on hand to help with rearing the infants (2).

The varied, omnivorous diet of the Malbrouck monkey includes a variety of leaves, gum, nuts, grasses, fungi, fruit, flowers and invertebrates and, less frequently, bird eggs, lizards and rodents (8).

Malbrouck monkey habitat

The Malbrouck monkey may be found in a variety of habitats, and is adaptable to rural and, in some cases, urban areas. It is abundant in open woodland, savannah and forest-grassland (1).

Malbrouck monkey status

Listed as Least Concern (LC) on the IUCN Red List (1) and listed on Appendix II of CITES (3).

IUCN Red List species status – Least Concern

Malbrouck monkey threats

Currently, the Malbrouck monkey is not considered at risk of extinction as it has a wide range, much of which has a low human population density, and faces no major threats (1)

Malbrouck monkey conservation

This species is listed on Appendix II of the Convention on International Trade in Endangered Species (CITES) (3) and is listed as Class B of the African Convention of Nature and Natural Resources, meaning that trade in this species must be controlled to avoid it being killed at a rate it cannot compensate for. This monkey can also be found in several protected areas (1).
