Bridging behavior among male Tibetan macaques (Macaca thibetana) was studied in a free-ranging group at Mt. Huangshan, China. This behavior was defined as a type of affiliative behavior in which two individuals simultaneously lifted up one infant. Bridging behavior occurred after an adult male carried an infant to another male or approached another male who was holding an infant. Each male frequently held and groomed a particular infant in the group, which was named an "affiliated" infant of the male. Males were more frequently provided with their affiliated infant by other males than with other non-affiliated infants. This finding suggests that male Tibetan macaques recognized the affiliative relationship between a male and his affiliated infant, and chose that infant for bridging behavior on the basis of this knowledge. Such choice might be important for effective bridging behavior or other affiliative interactions between males. © 1995 Wiley-Liss, Inc.
