“…This lack of an effect for demonstrator species may simply be an indication of the considerable cohesion, integration and tolerance of tamarin mixedspecies troops in the wild and in captivity. It is reported that more affiliative inter-specific interactions occur in captivity (e.g., grooming and social play: Heymann and Sicchar-Valdez, 1988;Heymann et al, 1996;Hardie, 1997). Certainly both species of observer in this study spent brief but frequent periods of time intently observing their demonstrators behaviour at the apparatus, regardless of their species.…”

Intra-and inter-specific social learning was investigated in two species of New World monkey, the saddle-backed tamarin {Saguinus fuscicoUis) and the redbellied tamarin {S. labiatus), which form stable and permanent mixed-species troops in the wild. We explored whether improved food acquisition, through social learning, is a potential advantage of mixed-species troop formation by allowing a pair of naive observers to watch a pair of trained demonstrators complete a novel foraging task. The aims of the study were (a) to determine if individuals succeeded at the task more quickly after having observed demonstrators, (b) to investigate whether speed of acquisition differed after observation of conspecific demonstrators as opposed to congeneric demonstrators, and (c) to compare performance between species. The number of trials taken by observers to succeed on the task was compared with that taken by naive demonstrators to succeed on the task initially. Individuals succeeded on the task more quickly if they had had the opportunity to watch demonstrators perform the task, regardless of whether the demonstrator was a conspecific or congeneric. There was no difference in performance between species. It is concluded that, for both species, the learning of a new foraging technique is facilitated by the presence of both conspecifics and congenerics and that the likely mechanism for this facilitation is a combination of stimulus enhancement and response facilitation. Social learning of this kind is discussed with respect its adaptive value in wild mixed-species tamarin troops.Tamarins of the genus Saguinus are small bodied (300-550g: Hershkovitz, 1977), diurnal, arboreal, South American primates which feed primarily upon insects, ripe fruits, nectar, and plant exudates (Snowdon and Soini, 1988;Garber, 1993). Their social lives are characterised by high levels of co-operation, tolerance and adaptability (Caine, 1993). When travelling and foraging troop members move in a cohesive manner (e.g., Yoneda, 1984a; Goldizen, 1987 for S.

“…The present study shows that interspecific interactions were almost entirely initiated by C. goeldii and C. pygmaea responded submissively. No interspecific affiliative interactions were observed, such as the grooming reported by Heymann & Sicchar Valdez (1988) between S. mystax and S. fuscicollis in a mixed group.…”

Primates are often considered problematic to house in mixed‐species exhibits. Here, a successful exhibit for Goeldi's monkeys Callimico goeldii and Pygmy marmosets Callithrix (Cebuella) pygmaea is described. These species are sympatric in nature, although there has been no evidence of interspecific association between wild groups. Both species are arboreal but they diverge in significant ways in their ecological niches. Data were collected to determine the compatibility of these species and to examine how the enclosure space was utilized. Interactions mainly comprised C. goeldii approaching C. pygmaea and the latter reacting submissively. Callimico goeldii and C. pygmaea utilized the enclosure space (height and furnishings) differently from each other but in a similar way to that described for each species in the wild. This factor may contribute to the peaceful co‐existence of C. goeldii and C. pygmaea in a mixed‐species exhibit at Edinburgh Zoo.

“…comm.). The only other known mixed-species tamarin group in captivity, prior to the present study, was at Iquitos, Peru, where five wild-caught S. mystax and six wild-caught S. fuscicollis were housed in an enclosure measuring 13 x 9 x 2.5 m high (Heymann & Sicchar Valdez, 1988). Although the method of introduction is not known the group was stable, which suggested that it was possible to keep mixed-species groups of tamarins in captivity.…”

Exhibiting mixed‐species groups of sympatric tamarins Saguinus spp at Belfast Zoo

In the wild sympatric tamarin species show a high degree of spatial co‐ordination. Stable associations between Saddleback tamarins Saguinus fuscicollis and members of the Saguinus mystax group (Red‐bellied tamarin Saguinus labiatus, Emperor tamarin Saguinus imperator and Moustached tamarin S. mystax) have been observed at all sites where the species co‐occur and are related to the stratification of ecological niches within the forest. Since 1992 a study of mixed‐species tamarin groups has been carried out at Belfast Zoo. Stable associations were established between groups of S. labiatus and S. fuscicollis, and few agonistic interactions were observed. Most aggression involved disputes over food and typically consisted of S. labiatus displacing S. fuscicollis, merely by approaching. Other interactions included some inter‐specific grooming and huddling. This paper describes the introduction procedure and the social and reproductive behaviour of each species within the group, and suggests that mixed‐species exhibits may be a beneficial way of exhibiting tamarins.
