Abstract: | Notification is a form of ritualized greeting behavior performed by adult male hamadryas baboons (Papio hamadryas). Originally observed in the wild when harem leaders signaled the direction of travel to their followers on daily foraging
marches, its true function is unknown. Notification involves the approach of an adult male baboon to another male, the presentation
of his hindquarters, then retreat. Researchers have previously linked notification to aggression avoidance, appeasement, and
the dominance-subordination relationship between males. We observed instances of notification over 6 mo among 8 adult males
in a troop of 61 captive-bred hamadryas baboons at Paignton Zoo Environmental Park, Devon, UK. We compared observation sessions
in which notification occurred with matched control periods. We classified different forms of notification according to the
recipient’s response: presenting, mounting, touching of the buttocks or genitals, or ignoring. Results suggest that different
forms of notification may have different functions, including submission, alliance, and peacekeeping but not general greeting,
recruitment, or appeasement. |
