| Abstract: | A longterm study of a population of patas monkeys (Erythrocebus patas) in Kenya indicated fluid male residence patterns. While a single adult male was present in each of the two main study groups for most of each year, several males were present and mating in groups during some conception periods. Tenures of males in heterosexual groups were generally short; some males were resident in both groups and some had more than one tenure in the same group. When not in heterosexual groups, males lived as solitaries or in all-male associations. |
