Age and sex differences in behavioural responses of Japanese macaques (Macaca fuscata) towards snakes

Key Points

• Macaques display varying behavioural responses to snakes depending on age and sex, indicating social and biological influences.
• Juveniles respond more defensively to snakes, while adults exhibit more varied behaviours based on sex, highlighting adaptation.
• Analysis of behavioural responses reveals significant differences among age groups and between sexes of the macaque population in natural habitats.
• Findings may enhance understanding of primate behaviour and evolution, as age and sex play critical roles in predator interactions.
