Affiliative interactions between singly-housed rhesus macaques in adjacent unmodified cages (1999)

Baker, K. C.

Abstract

Both males and females interacted with neighbors with a mean frequency of three times per hour; affiliative behavior made up approximately 60% of male-male interactions and 90% of female-female interactions. ... The extent of both male-male and female-female affiliation, despite substantial physical and visual restrictions, underscores the social needs of captive rhesus macaques.Female rhesus macaques manipulated their enrichment toys less after social introduction via protected contact.
