Scholarcy highlights
- In this paper we address a series of questions concerning reproductive opportunities, kinship, dispersal, and mating patterns in free-ranging moustached tamarin monkeys
- Between 1980 and 1990 information on group size, composition, and migration patterns was collected on marked groups of moustached tamarins inhabiting Padre Isla, an island in the Amazon Basin of northeastern Peru
- Mean group size was 7.0, including 2.2 adult males and 2.0 adult females. None of these groups was characterized by a single adult male-female pair
- An examination of dispersal patterns indicates that transfers between groups were common and fell into several categories, including immigration of individual males and females, simultaneous transfer of pairs of subadult and/or adult males into the same social groups, and group fissioning in which males and females of the splinter group join another small social group
- We have no unambiguous cases of 2 adult/subadult females migrating together into the same social group
- All 6 groups for which reproductive data were available were characterized by either a polyandrous or polygynous mating pattern
