Sun-tailed monkey  (Cercopithecus solatus)

The diet of this diurnal species consists of fruits, seeds, herbaceous plants, insects and small vertebrate prey (8). Although spending much of their time on the ground during the day, groups will sleep in the canopy, 10 to 15 meters above the ground (9). Mean group size for this species is 17 individuals (8) (10), consisting of one male and multiple females, although solitary males are known to occur (6) (8). The sun-tailed monkey has a polygynous mating system (9), and adult males will actively defend their groups from other males trying to usurp them (11). Whilst males disperse from their natal group, females remain, and a dominance hierarchy exists amongst these females, which is subsequently inherited by their offspring (11). The sun-tailed monkey gives birth to a single offspring, and the age of first reproduction for females is about 4 years old (9).
