Dominance, grooming, and clasped-sleeping relationships among bonnet monkeys in India
Social relationships, including dominance, grooming, and clasped-sleeping, were studied in a troop of bonnet monkeys (Macaca radiata) at Dharwar, India, the study period lasting two months and a half. Three measurements, the peanut test, the drinking test, and the spatial distribution test, were used to analyze dominance relationships. The peanut test showed a straight linear ranking order among adult males and females; however, among females drinking and spatial distribution orders are slightly different from that of feeding (peanut test). Grooming was observed more frequently between adult female and adult female and was seldom observed between adult male and juvenile female or between juvenile male and juvenile female. Apparently all monkeys tend to groom with females. On the other hand, monkeys of the same sex tend to sleep with each other. It is clear that monkeys select their partners when they groom and sleep.
