Social animals benefit from their group-mates, so why do they sometimes kill each other’s offspring? A major barrier to understanding the evolution of infanticide is a lack of data from natural populations. Especially when perpetrated by females, infanticide remains poorly understood, because the increased mating opportunities that explain infanticide by males do not apply in females. Using 30 years of data from several spotted hyena groups, we show that infanticide is a leading source of… 
Female-committed infanticide followed by juvenile-enacted cannibalism in wild white-faced capuchins.
On 5 February 2021, we observed the first instance of female-committed infanticide followed by cannibalism in a long-studied (> 35 years) population of wild white-faced capuchins (Cebus imitator) in
Death is common, so is understanding it: the concept of death in other species
It is argued that the CoD requires relatively little cognitive complexity and that it can emerge independently from mourning behaviour, and, so, it can expect to be fairly common in nature.


The evolution of infanticide by males in mammalian societies
Comparisons are used to show that infanticide primarily evolves in social mammals in which reproduction is monopolized by a minority of males, and is successfully prevented by female sexual promiscuity, a paternity dilution strategy.
Infanticide by males and its implications: Infanticide by female mammals: implications for the evolution of social systems
The purpose of this chapter is to examine the phenomenon of infanticide by females other than the mother (hereafter “infanticides by females”) in a variety of mammalian taxa.
Adaptations of Female Lions to Infanticide by Incoming Males
A simple model is presented that specifies one set of conditions under which a female will improve her lifetime reproductive success by showing temporary periods of infertility, but attracting a larger coalition.
Countering infanticide: Chimpanzee mothers are sensitive to the relative risks posed by males on differing rank trajectories.
The results support the sexually selected hypothesis for infanticide and demonstrate that female chimpanzees are sensitive to the relative risks posed by adult males.
Intra-community infanticide in wild, eastern chimpanzees: a 24-year review
A full record of all intra-community infanticides and failed attempts at infanticide over a 24-year period for the Sonso community of chimpanzees in the Budongo Forest, Uganda is presented to test four hypotheses for this behavior: the sexual selection hypothesis, male mating competition, resource competition, and meat acquisition.
Infanticide and expulsion of females in a cooperative mammal
Female helpers initially resist expulsion and repeatedly attempt to return to their natal group, indicating that it is unlikely that dominant females need to grant them reproductive concessions to retain them in the group.

Social Dynamics of a Captive Dingo Pack: Population Regulation by Dominant Female Infanticide
The social organization and dynamics of a captive dingo colony was studied to understand behavioural mechanisms of population regulation and provide insight into the significance of the copulatory tie in canids and an additional explanation for the increase in dingo numbers in Australia since European settlement.
Sexual conflicts in spotted hyenas: male and female mating tactics and their reproductive outcome with respect to age, social status and tenure
Female mate choice matched observed patterns of affiliative male–female behaviour, indicating that affiliative behaviour is a successful male mating tactic, and was consistent with the idea that male tenure may serve as an index of male quality, although male fertility may decline with extreme old age.
Social support drives female dominance in the spotted hyaena
It is shown that social support can drive sex-biased dominance and provides empirical evidence that a sex-role-defining trait can emerge without the direct effect of sex.
