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

Use of experimenter-given cues in visual co-orienting and in an object-choice task by a new world monkey species, cotton top tamarins (Saguinus oedipus).

Two methods assessed the use of experimenter-given directional cues by a New World monkey species, cotton top tamarins (Saguinus oedipus). Experiment 1 used cues to elicit visual co-orienting toward distal objects. Experiment 2 used cues to generate responses in an object-choice task. Although there were strong positive correlations between monkey pairs to co-orient, visual co-orienting with a ...

An Assessment of the Population of Cotton-Top Tamarins (Saguinus oedipus) and Their Habitat in Colombia

Numerous animals have declining populations due to habitat loss, illegal wildlife trade, and climate change. The cotton-top tamarin (Saguinus oedipus) is a Critically Endangered primate species, endemic to northwest Colombia, threatened by deforestation and illegal trade. In order to assess the current state of this species, we analyzed changes in the population of cotton-top tamarins and its h...

Selective Phonotaxis by Cotton-top Tamarins

When nonhuman animals vocalize, signal receivers are provided with a range of potential acoustic information concerning the signaler’s body size, sex, individual identity, kinship and group membership. Here we explore whether cotton-top tamarins (Saguinus oedipus) extract such information from their species-typical combination long call using a modiŽ cation of the phonotaxis assay originally de...

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

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 tamarins using focal animal scan sampling in 10 min block...
