Anti-predator behaviour of the red-legged partridge Alectoris rufa (Galliformes: Phasianidae) to simulated terrestrial and aerial predators

摘要: Abstract This study is intended to investigate the differences in anti-predator behavioural and acoustic response terrestrial aerial predators as well between sexes red-legged partridge. To this aim we observed of 114 partridge (57 males 57 females) dummy predators, a raptor fox. We divided responses into four mutually exclusive categories: vigilance, freezing, escape non-anti-predator behaviours. also recorded analysed vocalizations emitted during tests. The animals reacted differently stimuli. reactions elicited by predator were ranked follows: escape, behaviours, freezing. Those Vigilance more frequently than aerial...
