“…Infanticide is the killing of an infant by an individual of the same species (Hrdy and 57 Hausfater 1984). Infanticide committed by males is widespread across primate species, 58 documented in the wild in 36 primate species and inferred in the wild in an additional 17 species 59 (Alvarez et al 2015;Gursky-Doyen 2011;Kane and Gnépa 2016;Palombit 2012;van Schaik 60 2000a). The widespread prevalence of infanticide in primates has necessitated its inclusion in 61 socioecological models explaining patterns of primate sociality and group fission-fusion 62 dynamics (Aureli et al 2008;Janson 2000;Koenig et al 2013;Sterck et al 1997).…”

“…Table 3 shows that when mothers are injured during successful infanticidal attacks, they are often injured on the extremities, consistent with the location of Walimah’s injury. Although rare, there are instances of male infanticide in primates where the male has taken an infant off of the female’s ventrum 7,120 . Based on the evidence, we conclude that the most probable cause of Walimah’s injury was a bite by a male orangutan during a successful infanticidal attack on her infant.…”

Infanticide as a male reproductive tactic is widespread across mammals, and is particularly prevalent in catarrhine primates. While it has never been observed in wild orangutans, infanticide by non-sire males has been predicted to occur due to their extremely long inter-birth intervals, semi-solitary social structure, and the presence of female counter-tactics to infanticide. Here, we report on the disappearance of a healthy four-month-old infant, along with a serious foot injury suffered by the primiparous mother. No other cases of infant mortality have been observed at this site in 30 years of study. Using photographic measurements of the injury, and information on the behavior and bite size of potential predators, we evaluate the possible causes of this injury. The context, including the behavior of the female and the presence of a new male at the time of the injury, lead us to conclude that the most likely cause of the infant loss and maternal injury was male infanticide. We suggest that in orangutans, and other species where nulliparous females are not preferred mates, these females may be less successful at using paternity confusion as an infanticide avoidance tactic, thus increasing the likelihood of infanticide of their first-born infants.

“…Indeed, in only three occasions was an adult, likely males, encroach within 5 m of a mother-infant pair, and on two occasions the intruding individual was immediately chased away by the mother, perhaps to prevent infanticide. In one case, in spectral tarsier, a neighbouring male was observed to kill an infant [26]. Although, in another solitary species, western tarsier, males were often captured in close proximity to infants suggesting that fathers may provide some allocare.…”

In this paper, I present the first observations on the ontogeny of tarsier infants during their first and second months and of the mother-offspring bond from birth until separation. Tarsier mother-infant pairs were observed to be solitary. Maternal care involved a cache and carry strategy with the infant spending around 66% parked alone whilst the mother was foraging. I observed the following behaviour: rest, grooming, suckling, play, being carried, jumping and climbing. Percentage of time spent in each activity was calculated. Furthermore, play was observed to include locomotor-, social-and object-directed behaviours. Acoustic communication between mother and infant was very frequent containing four different signals. During the first days after birth, the mother transported the infants about, but within a week, the infants started climbing branches on their own. For the first three weeks, the mothers carried infants orally after which they started to follow the mother over shorter distances, although for longer distances, up to 50 days of age, the mothers continued to carry them. The inter-birth interval was around 1 year, but the infants from the previous birth continued to sleep with the mother for up to 10 months.
