Do zoo animals use off‐exhibit areas to avoid noise? A case study exploring the influence of sound on the behavior, physiology, and space use of two pied tamarins (Saguinus bicolor)
Noise can be a known stressor but our understanding of its effects on animals living in zoo environments remains limited. Although exposure to loud, chronic noise may be expected to negatively impact welfare, providing access to quiet areas to escape loud noise may buffer these negative effects. In this study, we explored the benefits of […]
The role of social context and individual experience in novel task acquisition in cottontop tamarins, Saguinus oedipus
In socially tolerant settings, naïve individuals may have opportunities to interact jointly with knowledgeable demonstrators and novel tasks. This process is expected to facilitate social learning. Individual experience may also be important for reinforcing and honing socially acquired behaviours. We examined the role of joint interaction and individual experience in the acquisition of a novel […]
Sex and helping: reproductive strategies of breeding male and female cotton-top tamarins, Saguinus oedipus
Female marmosets and tamarins typically give birth to twins, and appear to need considerable assistance from the male and from other group members if they are to rear the young successfully. To ensure that male help is available, females would be expected to increase the time they devote to the pair relationship shortly before birth. […]
Cage Design and Forms of Play in Red-Bellied Tamarins, Saguinus labiatus
Abstract 10.1002/zoo.1430110310.abs We investigated the role of cage design in the expression of play in a group of red-bellied tamarins (Saguinus labiatus). For each of the four play behaviors that were measured in this study (wrestle, pounce, grasp, and chase), significant differences in frequency appeared as a function of substrate. When playing on broad, flat, […]
Moving callitrichid monkeys from cages to outside areas
Abstract 10.1002/zoo.1430080206.abs To assess the important aspects of a large area for environmental enrichment, the behavior of families of common marmosets Callithrix jacchus and cotton-top tamarins Saguinus oedipus when in laboratory cages and when in much larger outside areas was compared. All animals avoided areas with little cover. The two tamarin families preferred an indoor […]
Fecal Concentrations of Cortisol, Testosterone, and Progesterone in Cotton-Top Tamarins Housed in Different Zoological Parks: Relationships Among Physiological Data, Environmental Conditions, and Behavioral Patterns
The aim of this investigation was to study the welfare of 3 captive groups of cotton-top tamarins housed in different zoological parks. Ethological observations were conducted during 1 year. In addition, fecal samples were collected and the concentrations of glucocorticoids, androgens, and progestogens were measured. Within each group, no significant differences in fecal cortisol concentrations […]
