Mirror-image responses in pygmy marmosets (Cebuella pygmaea)

The pygmy marmosets displayed a rapid extinction of social threat responses to their own image and of novelty responses to mirrors, but continued to show mirror-specific responses such as following their own image, playing peek-a-boo, and looking at their image...

Reconciliation and redirected affection in rhesus monkeys

The question whether rhesus monkeys reconcile was empirically translated as: Do they seek non-agonistic contact with former adversaries? The study concerned a captive group of forty-one monkeys, Macaca mulatta. Participants in 350 aggressive incidents were followed both immediately after the...

Cage-size effect on locomotor, grooming and agonistic behaviors of the slow loris (Nycticebus coucang)

Results of the experiments in this study indicate that slow lorises kept in larger [furnished] cages will be more active than those housed in [furnished] cages approaching recommendations for size proposed by the U.S. National Research Council.

Self-aggression in macaques: five case studies

All [5 adult males] were individually caged. Four of the animals showed an increased level of SIB during stressful situations, such as movement of an animal to a new cage, escape of other monkeys. Only one monkey showed SIB in...

Spatial pattern in a troop of yellow baboons (Papio cynocephalus) in Tanzania

Observations of adult and subadult yellow baboons (Papio cynocephalus) revealed class differences in spatial pattern both during movement and when at rest. males tended to spend slightly more time on the periphery than did females, and travelled more at the...

Male dominance in the bonnet macaque: A malleable relationship

The bonnet macaque may possibly show the highest degree of male-male tolerance in the genus Macaca. Five pairs of unfamiliar adult males were formed without any preliminaries. As usually occurs when unfamiliar males first meet, agonistic behaviors related to the...

Allowing captive primates to forage

A woodchip litter substrate reduces abnormal behaviours, primarily self-aggression, and encourages foraging, even in the absence of grain. Comparison between the bare floor and litter with grain showed that in the latter monkeys foraged more, manipulated the environment less, were...
