    Male Influx, Infanticide, and Female Transfer inMacaca radiata radiata
    Type
    Report
    Description
    In bonnet macaques, males usually disperse between groups and females remain philopatric, but researchers have reported female transfer. We reporta rare case of male influx during the mating season in our bonnet macaquestudy group in the Anaimalai Hills. The density of bonnet macaques in thestudy region was unusually high. The study group had a single, crippled adultmale with a long tenure and 5 adult females. During the mating season, adult females approached and mated with outgroup males, and then several malesentered the group. The adult male left the group without any resistance. Theincoming males mated with 3 receptive females, forcibly mated with 2 lactating females, and attacked and killed 2 infants. During the influx, 2 outgroup females joined the group. The data suggest that male influxes providean opportunity for infanticide and female transfer, which can have importantfitness consequences even in species in which they rarely occur.
