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

Hysteresis effects in a motor task with cotton-top tamarins (Sanguinus oedipus).

The way human adults grasp an object is influenced by their recent history of motor actions. Previously executed grasps are often more likely to reoccur on subsequent grasps. This type of hysteresis effect has been incorporated into cognitive models of motor planning, suggesting that when planning movements, individuals tend to reuse recently used plans rather than generating new plans from scr...

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...

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...
