“…This method provided mental stimulation and simulates the maternal carrying that a parent‐reared individual would experience. This is a method used to hand‐rear other primates (Sodaro & Weber, ) and research suggests that it may reduce the likelihood of stereotypical rocking behaviour in cebids, the theory being that stereotypical rocking is an infant's attempt at replicating the constant rocking movement of the gait of its absent mother (Visalberghi & Riviello, ). No incidences of stereotypical rocking have occurred in the hand‐reared Woolly monkeys at Monkey World.…”

Woolly monkey populations are decreasing in the wild and in captivity. Woolly monkeys have a reputation for being difficult to keep and breed, infant mortality is high and hand-rearing is rarely attempted or successful. Between 2006 and 2008, three Η Woolly monkeys Lagothrix lagotricha born at Monkey World -Ape Rescue Centre, UK, failed to suckle and these infants were removed for hand-rearing. Because no published information was available to inform our procedures, detailed records of the hand-rearing and reintroduction process were kept, and an account is provided here. Although parent-rearing is always the best option, this paper details the hand-rearing and reintroduction process used successfully at Monkey World in order to encourage other keepers who are managing suboptimal birth circumstances in captive Woolly monkey populations.

“…Several studies have described successful reintroductions of temporarily handreared young orangutans to their mothers [Hamburger, 1988;Keiter et al, 1983;Norcup, 1998;Sodaro and Weber, 2000]. Successful introductions of infant orangutans to surrogate mothers have also been described [Maple, 1980;Sodaro, 2007].…”

The behavior of a zoo‐housed infant orangutan after the death of its mother

The behavior of an infant female orangutan at Dublin Zoo before and after the death of her mother was recorded using scan sampling and compared. Social interactions and associations of the infant with the other individuals in the group were also compared before and after the death of her mother. Increases in climbing and object manipulation were observed, and a decrease in resting occurred. The infant orangutan significantly increased the amount of time she spent in close contact with another related adult female in the group after her mother's death. This case study describes an example of a zoo-housed infant orangutan being successfully fostered by a related female without human intervention. It also provides a quantification of the behavior of an infant orangutan before and after being orphaned. Zoo Biol 30:205-211, 2011. © 2010 Wiley-Liss, Inc.

“…When a mother dies or does not take care of her infant, an appropriate solution is to introduce it to a lactating female for adoption, as already achieved in some captive groups (van Wullften Palthe and van Hooff, 1975;Taub et al, 1977). However, in most cases no nursing female is available and the newborn must be removed from its group and hand reared (Keiter et al, 1983;Dronzek et al, 1986;Visalberghi and Riviello, 1987;Sodaro, 1993aSodaro, , b, 2000Sodaro and Weber, 2000;Abellò et al, 2007;Cross, 2007;Abellò and Colell, 2009;Barnes and Cronin, 2012). Although this practice may be successful in terms of infant survival, it means that the infant spends the early stages of its life away from its conspecifics.…”

“…The separation of the neonate from its mother may be brief and last just a few days (Keiter et al, 1983) or even a few hours (Barnes, 2012), in which case reintroduction is straightforward because the mother is still lactating and may accept to take her offspring back. Most reintroductions described in the literature involve small captive groups of no more than a few adult females and/or one adult male, plus immature individuals (Meyer and Wilcox, 1982;Dronzek et al, 1986;Visalberghi and Riviello, 1987;Watson and Petto, 1988;Sodaro, 1993a, b;Sodaro and Weber, 2000;Abellò et al, 2007;Cross, 2007;Abellò and Collel, 2009;Barnes and Cronin, 2012). Introducing an individual into a multi-male multi-female group is particularly risky.…”

Reintroduction of separated individuals into their social group is a major problem in the management of captive group of non-human primates. Here we report a case in captive Tonkean macaques in which a female infant was abandoned by her mother after birth, then removed, hand-reared, and reintroduced after weaning to her original group in several stages. After the initial phase of separation, a period of habituation to group members followed during which the infant was brought to the front of the group enclosure daily for two months. We then started a phased reintroduction process that lasted a year. Because the biological mother was the group member most attracted to the infant, the process began by allowing the two individuals to interact. In the next stages, we introduced the infant to the other individuals one after the other, starting with the females. Females then acted as protectors against potential male aggression. At the age of one year and two months, the introduced individual had fully integrated her original group. Two years later, she appeared to behave like the other group members. This report shows that a phased process can be used to reintroduce an infant to a macaque group containing several adult females and males.
