The Effect of the Captive Environment on Activity of Captive Cotton-Top Tamarins (Saguinus oedipus)

This study examined captive cotton-top tamarin (Saguinus oedipus) behavior across 3 different exhibits: (a) a rainforest (30.5 m in diameter), where tamarins free-ranged with other species; (b) a caged outdoor exhibit (5 m in diameter); and (c) a caged enclosure, with access indoors (6 x 9m) and outdoors (2.5 x 2.5 m). The study observed […]

Factors influencing stereotyped behavior of primates in a zoo

Abstract 10.1002/zoo.1430130308.abs Stereotyped behavior is the uniform repetition of a motor pattern that occurs at a higher frequency than considered typical for a species when observed in a natural environment. Stereotypies may be considered atypical behavior and usually indicate that an animal’s psychological welfare is at a suboptimal level. Instantaneous scans at 30-sec intervals during […]

Reactions of Zoo Visitors to Free-Ranging Monkeys

This study assessed the potential of two types of primate exhibit both for enhancing zoo visitors’ interest, knowledge, and enjoyment and for promoting conservation education. Visitors’ reactions to a free-ranging group of cotton-top tamarins were compared with their responses to caged tamarins in three ways: 1) timing how long visitors spent at each exhibit, 2) […]

Cage sizes for tamarins in the laboratory

Provision of adequate space for captive animals is essential for good welfare. It affects not only their behaviour but also determines whether there is sufficient room for appropriate environmental enrichment. Most importantly, appropriate cage size permits captive animals to be housed in socially harmonious groups and to fulfil their reproductive potential. For animals used in […]

Social Effects via Olfactory Sensory Stimuli on Reproductive Function and Dysfunction in Cooperative Breeding Marmosets and Tamarins

Most primates are social species whose reproduction is influenced by their social relationships. The cotton-top tamarin, Saguinus oedipus, and the common marmoset, Callithrix jacchus, are cooperative breeding species where the family structure alters reproductive function in many ways. While primates receive social effects on reproduction via all sensory stimuli, the marmosets and tamarins are particularly […]

Whisper-like behavior in a non-human primate

In humans, whispering has evolved as a counteractive strategy against eavesdropping. Some evidence for whisper-like behavior exists in a few other species, but has not been reported in non-human primates. We discovered the first evidence of whisper-like behavior in a non-human primate, the cotton-top tamarin (Saguinus oedipus), in the course of investigating their use of […]
