Measurement of enrichment device use and preference in singly caged baboons

The present experiment employed both observational data and miniaturized, electronic activity monitors attached to the enrichment devices to precisely measure their use. ... When average device movement times were compared, baboons generally interacted less with Kongs than with logs or...

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...

Environmental enrichment for Old World primates with reference to the primate collection at Edinburgh Zoo

Enrichment in primates was shown overall to have a strong bias towards the great apes and terrestrial/semi-terrestrial species in general. .... The lives of captive primates everywhere could be enhanced by developing programs by which keepers could gain greater access...

Free roaming enrichment and exercise room

Monkeys were brought into the room in their cage as pairs and then released. Each pair is in the room approximately 1.5 hours at least once every 10 days. At the end of the enrichment period, a clean cage with...

Use of an inexpensive foraging device by four primate species: Patterns of food acceptance and foraging time

These data clearly indicate that what may be a very useful foraging device or food for some primate species may be less effective, or at least differentially effective, for other species.

Enriching the social experience of young motherless monkeys with companion animals

Positive social contact, companionship, and long-term relationships developed with both dogs and horses. Yearling sheep were tolerant of the [young, group-housed] monkeys, but cats were not.

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...

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...

Operant conditioning as an enrichment strategy at the San Diego Zoo

It was during the training that we discovered that the operant conditioning [of the group-housed bonobos] was having an unexpected and profound effect; it was providing enrichment for the animals.
