在Kibale国家公园的Kanyawara研究小组观察到对一名母亲和2岁婴儿的长期攻击，导致婴儿死亡。母亲是一个边境地区的居民谁第一次被观察到与单位组男性六年前。袭击者是一只成年雄性和一只成年雌性，一只6周大的婴儿紧紧地抱在她的腹侧。这次袭击在几个方面都很不寻常：这是第一次观察到雄性和雌性黑猩猩密切合作进行捕杀;成年雌性最初试图代表受害者进行干预，但后来在受到雄性攻击后加入了攻击;并且该发作的持续时间比其他报告的病例长。在事件发生后的一年里，母亲没有增加与社区男性的联系，但有人看到她与杀死她婴儿的男性在一起。这些观察结果的相关性，以性选择为基础的解释，在黑猩猩杀卵剂进行了讨论。
A prolonged attack on a mother and 2-year-old infant that resulted in the death of the infant was observed in the Kanyawara study group in Kibale National Park. The mother was a border-area resident who was first observed associating with unit-group males six years previously. The attackers were an adult male and an adult female with a 6-week-old infant clinging ventrally to her. The attack was unusual in several respects: it is the first time a male and a female chimpanzee have been observed cooperating closely in an infanticidal attack; the adult female initially attempted to intervene in the victim's behalf, but later joined in the attack after receiving aggression from the male; and the episode was longer in duration than other reported cases. In the year following the incident, the mother did not increase her association with community males, but was seen with the male who killed her infant. The relevance of these observations to sexual selection-based explanations for infanticide in chimpanzees is discussed.
