Events surrounding an infant-killing following a male takeover are described for a group of free-ranging howling monkeys in Costa Rica, and additional evidence is presented for infant disappearances following three previous male takeovers. Infant-killing is best interpreted in this context as a male reproductive strategy, as infant-killing did effectively shorten the interbirth interval, and only infants of high-ranking females died or disappeared following a male takeover. Due to the exclusive access of the dominant male to high-ranking estrous females, an incoming male who had lived as a peripheral male before taking over the group would run little risk of eliminating his own offspring in the course of killing the offspring of high-ranking females.
描述了哥斯达黎加一群野生吼猴中一起杀婴事件，并提供了此前三次雄猴接管后幼猴失踪的更多证据。在这种情况下，杀婴最好被解释为一种雄性繁殖策略，因为杀婴确实有效地缩短了生育间隔，只有高等级雌性的幼崽在雄猴接管后死亡或失踪。由于占优势的雄性对高等级发情雌性具有专有权，因此，在接管群体之前一直作为边缘雄性生活的新来雄性在杀死高等级雌性的幼崽时，几乎不会有消灭自己后代的风险。
