| Abstract: | Five red‐capped mangabeys (Cercocebus torquatus) were gradually introduced to an established mixed‐species exhibit containing six black and white colobus, seven mandrills, and six sooty mangabeys. Interspecific interactions were documented throughout the 3‐month introduction period and for an additional 3 months immediately thereafter. In addition, each species' behavior and exhibit use were documented before and after the addition of the fourth species. Minimal interactions were observed between the red‐capped mangabeys and the colobus or mandrills, and neither species was significantly affected by this addition. Many affiliative and aggressive interactions and changes in behavior were documented in the sooty mangabeys. However, this study shows that even closely related allopatric species can coexist in a captive environment, and the animals can benefit from this association.
