Causes of body rocking in chimpanzees (Pan troglodytes)

The development of rocking may be prevented if the babies are left with the mother and in their social group. Rocking after (late) separation may be prevented when transfer takes place together with familiar peers.

Urinary endocrinology and social dynamics: a method for monitoring entire marmoset groups

In order to obtain the essential endocrinological data sets we rely on stress-free and simultaneously collected individual urine samples from entire family groups. In common marmosets (Callithrix jacchus), this has been achieved and the methodology is clearly described.

Wounding aggression during the formation and maintenance of captive, multimale chimpanzee groups

Based on a 14-year survey of one facility, the incidence of injuries resulting from aggression during and after group formation of chimpanzees is assessed and its managerial implications discussed. There is more wounding and more severe wounding in groups composed...

Tamarin enrichment at the Utica Zoo

Creating new enrichment devices is one of the most challenging aspects of our job. Various enrichment devices were successfully tried with our golden lion tamarins and saddle-back tamarins such as branches, insect feeders, hanging fruit from perches, heat lamps, popsicles,...

Age and gender differences in response to food enrichment in family groups of captive marmosets (Callithrix, Callithrichidae)

The proximity of individual members of three family groups of marmosets was measured to two sources of food namely, on the introduction of their normal daily ration (baseline behaviour) as well as to a previously unfamiliar 'preferred' food [grapes]. Significant...
