Tonkean macaque description

KingdomAnimalia
PhylumChordata
ClassMammalia
OrderPrimates
FamilyCercopithecidae
GenusMacaca (1)

Of all the non-human primate groups, none is more widely distributed than the macaques, a genus of heavy-built, old-world monkeys (4). The Indonesia island of Sulawesi is home to several closely related macaque species, one of which is the Tonkean macaque (1) (2) (4). In common with the other Sulawesi macaques, the Tonkean macaque has strong limbs, a moderately long snout, and a short, inconspicuous tail (2) (5) (6). The pelage of this species is predominately black, with areas of lighter brown on the cheeks and rump (2). On the edges of its range, the Tonkean macaque is known to hybridise with several other Sulawesi macaques, including the booted macaque (Macaca ochreata), the Celebes macaque (M. maura) and Heck’s macaque (M. hecki) (1).

Also known as
Tonkean black macaque.
Synonyms
Macaca hypomelanus, Macaca togeanus, Macaca tonsus.
French
Macaque De Tonkea.
Spanish
Macaca De Tonkean.
Size
Average male weight: 14.9 kg (2)

Tonkean macaque biology

Except for a handful of recent studies, there has been very little research focusing on the ecology of the Tonkean macaque (1) (4) (7). As a result, there is scant information on this species’ group behaviour, but troops of 10 to 30 individuals, comprising multiple sexually mature adults of both sexes, have been documented (7). Although the Sulawesi macaques are generally considered to be semi-terrestrial (5), the Tonkean macaque appears to spend most of its time moving around in the tree canopy (7). Active during the day, it feeds primarily on fruit, but will also consume leaves, flower-stalks, insects and other invertebrates. In the vicinity of farmland, this species is also known to raid crop plantations for maize, fruit and vegetables, bringing it into direct conflict with human activities (1) (7).

Classified as Vulnerable (VU) on the IUCN Red List (1) and listed on Appendix II of CITES (3).

IUCN Red List species status – Vulnerable

Tonkean macaque threats

Despite still being common in areas of suitable habitat, the continuous conversion of rainforest into agricultural land, especially for oil palm and cocoa plantations, is having a notable negative impact on the overall population of the Tonkean macaque (1). Furthermore, as the amount of natural habitat diminishes, the Tonkean macaque has become increasingly dependent on crops for survival, resulting in conflict with local farmers, who treat this species as an agricultural pest (1) (7). Other threats include hunting for food and the trapping of wild macaques to keep as pets (1).

Tonkean macaque conservation

In addition to being listed on CITES Appendix II, which prohibits trade in this species without a permit, the Tonkean macaque occurs within several protected areas across it range (1) (3). In order to tackle wildlife crime in Sulawesi, a Wildlife Crimes Unit was established in 2001 by the Indonesian Department of Forestry and the Wildlife Conservation Society. The unit has been highly effective at reducing trade in some protected mammals and is working with local communities to strengthen conservation awareness (8) (9).
