For years, infanticide by males was thought to be unlikely in multi-male primate species. Recent studies have, however, presented evidence of infanticide in such species and a recent model by Broom and colleagues predicts that males' age and rank influence the occurrence of infanticide: youngest and highest-ranking immigrant males are more likely to commit infanticide than their older and lower-ranking counterparts if putative fathers fail to protect infants. I collected data on adult free-ranging sooty mangabey females in the Ta? National Park, Ivory Coast, over 11 months including a birth and a mating season. Infanticide had been previously reported in captivity for this species, but not in the wild. Several males entered the group prior to and during the mating season. As predicted by the model, only the more dominant immigrant ones attacked mother-infant pairs significantly more often than did other males. Mothers often reacted with counter-attacks. Potential fathers guarded and supported infants and mothers throughout the period of infant vulnerability. Furthermore, as only one of seven infants died despite 136 observed attacks on mother-infant pairs and unattended infants by immigrant males, we conclude that cooperation between putative fathers and mothers represents an effective protection against infanticide.
