“…Our observations of infant care by the original resident male during the first month of life of the infant are in general agreement with previous reports of infant care in this species (Rotundo et al 2005), as well as in other species of owl monkeys (Dixson and Fleming 1981). The mother was the main carrier during the first few weeks of life.…”

Owl monkeys (Aotus azarai) are small, territorial, socially monogamous primates that show intense infant care by the adult male in the group. It has been hypothesized that male care may be adaptive because it increases offspring survival and/or reduces the metabolic costs to the female of raising the offspring. Alternatively, males may provide care even when they are not related to the infants to increase future reproductive opportunities. We describe changes in infant care patterns that took place following the eviction of the resident male by a solitary male in an owl monkey population in the Argentinean Chaco. The resident male and mother provided all infant care during the first month of life of the infant, until the male was evicted. During the 3-day male replacement event, care of the infant was shared among the mother, a 4-year-old sister, and a 1-year-old brother. The new male began contributing to infant care soon after entering the group, carrying, and interacting socially with the infant in much the same way as any male regularly does. However, despite receiving biparental care from both the original and new resident males, the infant disappeared at the age of four months and was presumed dead. These are the first reports of care by sibling and by non-putative fathers in wild owl monkeys. Given the significant amount time that new pairs of owl monkeys spend before reproducing, it is possible that male care in owl monkeys functions as mating effort as much as or more than parenting effort.

“…During the fi rst month of life, infants are almost constantly carried by their parents. By the third month of life, they spend half the time off their parents, and by the fourth month they move independently more than 90% of their time (Dixson and Fleming 1981 ;Rotundo et al 2005 ;Wright 1984 , dashed line in Fig. 16.1a ).…”

“…In the Argentinean Chaco, long-term pairs of Azara's owl monkeys often have one infant every year between September and December (Fernandez-Duque 2002 ) . Both adults groom and clean the infant frequently with the mouth in captivity (on average 0.65 bouts/h, Dixson and Fleming 1981 ) , but grooming seems to be less frequent in the wild (Fernandez-Duque et al unpublished data;Wright 1984 ) . During the fi rst month of life, infants are almost constantly carried by their parents.…”

Building Babies

In contrast to birds, male mammals rarely help to raise the offspring. Of all mammals, only among rodents, carnivores, and primates, males are sometimes intensively engaged in providing infant care (Kleiman and Malcolm 1981). Male caretaking of infants has long been recognized in nonhuman primates (Itani 1959). Given that infant care behavior can have a positive effect on the infant’s development, growth, well-being, or survival, why are male mammals not more frequently involved in “building babies”? We begin the chapter defining a few relevant terms and introducing the theory and hypotheses that have historically addressed the evolution of paternal care. We then review empirical findings on male care among primate taxa, before focusing, in the final section, on our own work on paternal care in South American owl monkeys (Aotus spp.). We conclude the chapter with some suggestions for future studies

“…When the solitary individual is successful, he/she soon begins interacting affiliatively with other group members and within few days is fully accepted into the group. Male owl monkeys show intense care of the infants (Dixson & Fleming, 1981;Wright, 1984;Rotundo et al, 2005;Wolovich et al, 2008). Most owl monkey species are strictly nocturnal, but the Azara's owl monkeys (A. azarai) of Argentina, Bolivia and Paraguay regularly show both diurnal and nocturnal activity (Wright, 1989;Fernandez-Duque, 2003;Fernandez-Duque & Erkert, 2006).…”

Natal dispersal in monogamous owl monkeys (Aotus azarai) of the Argentinean Chaco

SummaryThis study offers a detailed description of natal dispersal patterns in owl monkeys (Aotus azarai) and evaluates the extent and characteristics of sex-biased dispersal in this monogamous mammal. Owl monkeys are small, territorial primates that live in socially monogamous groups in the Argentinean Chaco. Between 1997 and 2007 we recorded the disappearance or dispersal of 102 individuals born in 24 social groups. All individuals, both males and females, left their natal group, and they did so when they were between 2.2 and 4.9 years of age. Most dispersal events occurred immediately before or during the birth season and very few of them occurred during the mating season. Males and females did not differ significantly in the timing of dispersal, the age when they dispersed or how far they dispersed. Dispersals during the harsher Fall/Winter season were associated with the eviction of one or both adults in the group. The limited data on the fate of dispersed individuals suggests that natal dispersal is a highly risk event in the life of owl monkeys. The data also provide adequate support for the inbreeding avoidance hypothesis for natal dispersal in this species.
