Tonkean Macaque

About this species

Tonkean macaques have an ape-like appearance, with males being slightly larger than females. A handful of matriarchs enforce a relatively lenient, though stable, pecking order. However, this peacefulness does not extend to outside troops. If two tonkean macaque troops cross paths, intense conflicts can arise. Studies show that male macaques often interacted with each other through facial displays and physical contact. High ranking males typically started these interactions. (Wikipedia, general species account).

These macaques take significant effort in maintaining harmony within the group and practice conflict resolution to a great degree. They use contact calls to communicate with each other able social events, and loudness depends on context and distance of the individual. Loud calls are used amongst members of the same social groups to inform other members of position and activity. Most calls are from males to other males in the same group.
