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

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...

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...

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) Expectations About Occluded Objects: A Dissociation Between Looking and Reaching Tasks

Recent work with human infants and toddlers suggests a dissociation between performance on looking and reaching tasks. Specifically, infants appear to generate accurate representations of occluded objects and their actions when tested in expectancy violation looking tasks but often fail to use this information when reaching for occluded objects. We explore a similar dissociation in cotton-top t...
