Abstract
In the present study, we obtained quantitative behavioral data on the integration process of an adult female with her dependent daughter into a resident zoo population of six bonobos (Pan paniscus). During the whole observation time of almost two months, the integration happened very peacefully without significant increases of aggressive or agonistic tendencies. The integration was mediated and actively supported mainly by two processes: contacts of resident infants and juveniles towards the immigrating animals and contacts of the immigrating adult female to a “specific senior female” of the resident group. Adult males and adolescent females seemed not to play a role in the social integration of new group members. The new adult female soon became a preferred partner for sexual interactions such as genito-genital rubbing. The social integration of the 18-month-old young was controlled by her mother and finished only after the adult female had reached a stable and safe position in the new group. According to our observations, the exchange of an adult female bonobo including her young between zoos has no negative effects on the animals involved.
