Husbandry and breeding of a newly-established colony of cotton-topped tamarins (Saguinus oedipus oedipus)

Food-sharing in cotton-top tamarins (Saguinus oedipus).

Food-sharing behaviour was observed in 9 captive families of cotton-top tamarins (range 4-14 individuals per group), during meals of fresh fruit. Food was transferred to infants by their parents and older sibs in response to begging, and was also offered to them without prior solicitation. Older, mature, reproductively suppressed individuals shared more than young immature monkeys. Infants in l...

Activity Profiles and Hormone Metabolites in a Captive Group of Eight Cotton - Top Tamarins , Saguinus oedipus

A two-choice preference assessment with five cotton-top tamarins (Saguinus oedipus).

A study selected 5 cotton-top tamarins (Saguinus oedipus) located at the Frank Buck Zoo in Gainesville, Texas, for a food preference assessment. The study used a paired-choice procedure across 7 different food items for all 5 tamarins. Preferences for the food items across all the tamarins varied, although general trends were noted as well. This article discusses the benefits of using paired-ch...

Cotton-top tamarins (Saguinus oedipus) fail to show mirror-guided self-exploration.

To investigate the problem of inter- and intraspecific differences on the mirror test, we conducted two experiments on cotton-top tamarins. Experiment 1 employed a technique similar to one used recently on chimpanzees, and provided no evidence of mirror-mediated touching of the marked area. In a control condition, involving colored dye applied to one arm, two subjects also failed to show self-d...

Pulling to scale: Motor planning for sequences of repeated actions by cotton-top tamarins (Saguinus oedipus).

Previous research has demonstrated that nontool-using primates are capable of sophisticated motor planning for a single action. The present study extends this work by asking whether monkeys are capable of planning a sequence of repetitive motor actions to accommodate a task demand. We presented tamarins with a tape measure baited with a food reward at near or far distances and measured their ma...
