Greeting movements among adult males in a colony of baboons:Papio hamadryas, P. cynocephalus and their hybrids
Seven greeting movements performed by four adult males belonging to a colony of baboons (Papio hamadryas, P. cynocephalus and their hybrids) were described.
The hamadryas male has more number and more refined repertoire of movements than the yellow baboons, what would mean that the greeting movements possess a species-specific nature. This characteristic is expressed also by the existence of some inappropriate responses of the yellow baboons to the greeting of the hamadryas male. The differences in the greeting movements between both species would be explained as characteristic consequences of their social system organization. The hybrid male, having acquired a system organization similar to that of the hamadryas male, has acquired the same signal code, too, according to this system.
The hybridization tendency would be adaptive in those colonies or troops with mixed species.
