Muna-Butung Macaque (Macaca brunescens)
This species has cheek pouches to carry food in while it forages.
The muna-butung macaque is found on the islands of Sulawesi which are part of the country of Indonesia. This species lives in the rainforests of moderate elevations.
This is a diurnal species. The muna-butung macaque feeds on fruit and leaves. Group sizes for this species range from 13 to 21 individuals.
The muna-butung macaque is a quadrupedal species (Fleagle, 1988).
The muna-butung 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 the muna-butung macaque when they 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).
The muna-butung macaque gives birth to a single offspring.
