Summary: Hilário & Ferrari (2010)

Infanticide is a common phenomenon, usually caused by polygynous males taking over a harem with unrelated infants. Hilário & Ferrari (2010) describe rwo incidences of infanticide in a free-ranging group of
buffy-head marmosets (Callithrix flaviceps) in 2008, the first observed incidence in this species. Over a 10-day period, 4 females within the group gave birth, with the infanticides occurring on the third and sixth days. The perpetrator in the first incident was unknown, but the socially dominant breeding female is likely to have caused both as she was observed ingesting the second infant's head. The behaviour appears typical of marmosets in general. The strategy of the socially dominant breeding female attacking offspring of subordinates is likely aimed at reducing competition for caregivers.
