We observed 8 females during the prepartum period, the day of birth, and the postpartum period in a wild troop of Japanese macaques (Macaca fuscata yakui) on Yakushima Island, Japan. We collected data on their activity budgets, quantitative feeding and foraging behavior, and on female-male interactions. On the day of birth, females spent less time moving and feeding, and more time resting relative to other periods. Overall dietary diversity as well as arthropod foraging also decreased on the day of birth. Females fed mostly on mature leaves, new leaves and shoots during prepartum periods but mostly on fruit during postpartum periods. Decreased feeding on leaves and increased feeding on fruit probably changed as a result of seasonal availability, independently of parturition. Feeding on flowers, fungi and other items remained constant over all periparturitional periods. On the day of birth, new mothers had fewer social interactions with males and spent more time out of proximity with other adults than in other periods. Females rejected grooming presentations from males, groomed less with males, spent less time ≤3 m of males, and received less aggression from males on the day of birth. In the postpartum period, interactions with males returned to prepartum values. Grooming with females did not differ across the three periods. These results suggest that interactions with males may be costly for females on the day of birth.
