“…data], in agreement with similar reports on other saki species [Rosenberger et al, 1996]. Male sakis provide little direct care for offspring [Homburg, 1998], unlike titi [Fragaszy et al, 1982;Mendoza and Mason, 1986a, b;Hoffman et al, 1995] or owl monkey males [Wright, 1984;Jantschke et al, 1996;Rotundo et al, 2002Rotundo et al, , 2005Fernandez-Duque, 2007], who, almost exclusively, carry infants from soon after birth. Thus, territory defense may be an important alternative 'service' that males provide for female sakis.…”

Sakis (genus Pithecia) commonly live in socially monogamous groups, but data from wild populations on group dynamics and on the turnover of reproductive-age animals are rare. Here we describe the replacement of the adult male in one group of sakis in the Ecuadorian Amazon following the death of the initial resident. We use 354 h of focal behavioral data to describe differences in the spatial relationships among group members before and after the replacement and to examine changes in the rate of male-to-female grooming, aggression, scent marking and vocalization. Interactions with extragroup individuals within the group’s home range were more frequent during and after the replacement than before. The presence of such additional animals during periods of reproductive turnover may explain at least some reported observations of saki groups with more than 1 reproductive-age male or female.

“…In captivity, a few studies have examined parental behavior and infant development in different owl monkey species (Dixson and Fleming 1981 ;Jantschke et al 1998 ;Wolovich et al 2007Wolovich et al , 2008Wright 1984 ) . Birth seasonality has been reported in wild, as well as in some captive owl monkey populations (Fernandez-Duque 2002, 2011aGozalo and Montoya 1990 ) .…”

“…Although the lack of groups without male care hinders an evaluation of the "maternal relief" hypothesis, there is some limited evidence to evaluate it. After the death of her mate, a captive owl monkey female had to bring up her infant with only the assistance of an older daughter (Jantschke et al 1998 ) . The older sibling provided substantial infant care, similar to the situation described for one wild group where the adult male died soon after the birth of the infant (Fernandez-Duque et al 2008 ) .…”

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

“…The only detailed studies of parental behavior and infant development have been conducted on captive groups of owl monkeys (Aotus azarai) by Dixson and Fleming (1981), Jantschke et al, (1996) and Wright, (1984). Parallel studies of infant development and parental behavior in free-ranging populations have been constrained by their nocturnal habits (Wright, 1985).…”

Infant Development and Parental Care in Free-Ranging Aotus azarai azarai in Argentina

Studies of infant development and parental behavior in free-ranging owl monkeys have been constrained by their nocturnal habits. Taking advantage of the cathemeral activity pattern of Aotus azarai azarai in the ArgentineanChaco, we describe the development of a cohort of free-ranging infants born in an owl monkey population in Formosa Province. We observed 7 infants, whose birth dates are known to the nearest week, to record details of their development and care between October 1999 and March 2000. We collected 92 h of behavioral data in 76 sessions. The infants were almost never off the parents during the first 4 wk of life, and we observed no infant being transported by a nonadult. The parent carrying the infant traveled most frequently in the middle of the group, sometimes first, but rarely last. The mean duration of 33 nursing episodes is 69 sec. After nursing, the infant was more likely to return to the nonnursing adult than to remain with the mother suggesting that in owl monkeys the infant may be primarily attached to the adult male in the group. Infants began to explore, to manipulate and to consume solid foods during the second month. Our observations are comparable to ones on captive breeding groups of Colombian owl monkeys (Aotus lemurinus) and Bolivian owl monkeys (A. azarai boliviensis) under controlled conditions of temperature, illumination and food availability.
