Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant and other adult monkeys. Males preferred to spend time with females without infants but still spent more time with females with infants than with males. Females without infants spent significantly less time with females with infants than with males or other females without infants and females with infants decreased their frequency of social interaction overall without preference for males, females or other females with infants.
