Adoption of an orphan infant in wild black and gold howler monkeys (Alouatta caraya)
Romina Pavé, Martín Kowalewski, Gabriel E. ZuninoThis study reports the first case of adoption in a wild group of black and gold howler monkeys (Alouatta caraya). After the death of one adult female with a dependent infant, her daughter with a dependent infant adopted the orphan of similar age of her own infant. We recorded the activity and proximity between the adopter and both infants during two following days. The adoptive female appeared to provide equal treatment toward both infants and the orphan seemed to recognize the female as his mother. This report suggests that adult females of A. caraya can rear two infants at once.
Adopción de un infante huérfano en monos aulladores negros y dorados (Alouatta caraya). En este estudio se cita el primer caso de adopción en un grupo silvestre de monos aulladores negros y dorados (Alouatta caraya). Luego de la muerte de una hembra adulta, su hija adoptó al infante huérfano de similar edad que su propio infante. Durante dos días seguidos registramos la actividad y proximidad de la hembra adoptiva y los dos infantes. La hembra adoptiva expresó igual trato hacia ambos infantes y el infante huérfano parecía reconocer a la hembra como su propia madre. Este estudio sugiere que hembras adultas de A. caraya pueden criar dos infantes a la vez.
