Social relationships in a newly established all-male group of lion-tailed macaques (Macaca silenus)

Observations covered the first nine weeks [after group formation]. The males interacted rarely. In 8 of 15 dyads grooming occurred. Aggressive behaviour normally occurred without physical contact. ... The males showed a tendency to use the same or adjacent rooms...

Effects of puzzle feeders on pathological behavior in individually housed rhesus monkeys

Self-injurious behavior (SIB) occurs in about 10% of individually housed monkeys. Monkeys with SIB bite their own bodies frequently, occasionally inflicting wounds as a result [p. 213] ... Of great concern is the development of a severe from of abnormal...

Practical aspects of the program to promote psychological well-being in nonhuman primates at the Oregon Regional Primate Research Center

A comprehensive inanimate and animate enrichment program for rhesus macaques is described and valuable recommendations made to facilitate optimal psychological well-being throughout the animals' lives. A successful (80% compatibility) pair formation protocol for female rhesus macaques is outlined. New pairs...

Behavioral effects of perches on group-housed adult female Japanese monkeys

When [4 adult female] monkeys were housed in a cage which contained eight wooden perches to increase usable space, the rate of agonistic interactions as well as the rates of spatial proximity and social grooming decreased in comparison with those...

The presence of visual barriers decreases antagonism in group housed pigtail macaques (Macaca nemestrina)

Instances of bite, grab and chase were found to be significantly greater [among members of harem groups of 23 pig-tailed macaques] when visual barriers were absent compared to when they were present.

Successful pair-housing of male macaques (Macaca fascicularis)

Potential companions were paired after establishment of a clear dominance-subordination relationship during a noncontact familiarization period. Throughout a follow-up period of 12-42 months, 16 of the 17 original pairs (94%) were compatible. Only one pair engaged in fighting shortly after...

Enrichment and exercise room for free roaming

A playroom outfitted with enrichment devices that are not possible in the standard cage is described. Each pair [of adult male long-tailed macaques] is in the room approximately 1.5 hours at least once every 10 days.

Pairing female Macaca fascicularis

Twenty-nine previously single-caged adult female long-tailed macaques were paired with each other in vertical, double-cage configuration. Partners were compatibly in 81% of cases. Neighboring pairs were often charging each other across the grid panel. ... To avoid this, pairs were...

Cage toys reduce abnormal behavior in individually housed pigtail macaques

Providing multiple manipulable toys as enrichment for [single-caged] pigtail macaques was effective in reducing abnormal behavior during 30- min observation session. The use of the toys was reduced over time. The Kong toy was used most consistently.
