Title: Notes préliminaires sur l’écologie de Cercopithecus Ascanius schmidti dans les environs de Bangui (R.C.A.)
Author: Galat-Luong, Anh
Abstract: Preliminary observations on the social structure and ecology of a troop of Red-tail monkeys (Cercopithecus ascanius schmidti) were made between 1970 and 1972 around Bangui, Central African Republic. The age-graded male troop studied ranged from 17 to 23 troop members, including 4 adult males, one of which (the GM male) was much bigger than the others, one subadult male (PN), six adult females, six juveniles and six infants. The troop very often splits into sub-groups by day as well as by night : « family parties » (Haddow, 1952) made up of one adult male and one adult female accompanied by its young of the year, female travelling parties, juvenile play groups. The association between the « master male » GM and the subadult male PN lasted for a whole year ; both of them were usually found staying outside the rest of the troop. The troop’s home range averaged 15 hectares, five of which representing the core area. Two different sleeping trees were used during the observation period. Some details are given on the diet, the daily schedule of activity, and their seasonal varia tions. Mating occured during the day and outside the group. Seaso nality of breeding is the rule ; six young infants were observed in September.
