Heck’s Macaque (Macaca hecki)
This species has cheek pouches to carry food in while it forages.
Heck’s macaque is found on the islands of Sulawesi which is part of the country of Indonesia.
Heck’s macaque is a frugivorous species. This is a diurnal species.
Heck’s macaque is a quadrupedal species (Fleagle, 1988).
Heck’s macaque has a multimale-multifemale social system. Females remain in their natal group with the onset of maturity, but males will disperse shortly before adolescence. There is a hierarchical system amongst group members based upon the matriline.
scream calls: This call is given by Heck’s macaque when they are approached by a non-group conspecific.
fear grimace: The lips are retracted so that the teeth are shown; the teeth are clenched together (Estes, 1991). This display functions as an appeasement signal to reduce aggression in aggressive encounters (Estes, 1991).
staring with open mouth: This is the stare accompanied by the mouth being open but the teeth are covered (Estes, 1991). This is a threat expression (Estes, 1991).
Heck’s macaque gives birth to a single offspring.
