Relationships between Female Howler Monkeys (Alouatta palliata) with & without Infants in Costa Rica
For group-living, bisexually dispersing primates, adult social bonds are likely to be strongest between males and females. Mantled howler monkeys (Alouatta palliata) live in social groups where adults engage in alloparenting and infanticide. We expected females with infants to be closer to males than to other females to prevent infanticide. In January 2019, we observed howler monkey groups in Costa Rica. Females with infants had males as nearest neighbors less often than expected, while other females had male neighbors more than expected. Females with infants may seek close proximity to other females due to the benefits of alloparenting.
