Age-specific reproductive behaviours in male roe deer Capreolus capreolus

摘要: The behaviour of active male roe deerCapreolus capreolus Linnaeus, 1758 was studied in a wild population on Storfosna island (Norway), during the pre-territorial and territorial seasons (February–August) 1994. Observed behaviours were grouped seven categories (mating, aggression, display, marking, vigilance, moving maintenance), proportion time spent each by three age classes (yearlings, subadults adults) compared. Time varied significantly between months for all classes. From February to August, maintenance decreased, while vigilance increased. mating increased both adult but did not vary yearlings throughout months. When comparing within month, there no significant differences behaviour. Surprisingly, males invest more mating, with respect subadults. This may be consistent oligogynous system deer, which reproductive success is divided amongst several years their territoriality, could tactic reduce competition mating.
