In primates, infanticide is occasionally observed during intergroup conflicts but does not fit the predictions of the sexual selection hypothesis. I report an observation of an intergroup infanticide during a sub-group foray in grey-cheeked mangabeys (Lophocebus albigena) at the Ngogo site in Kibale National Park, Uganda. Intergroup infanticide appears to be a form of extreme and longterm food defence across primate species, and occurs in conjunction with other forms of food defence.
