Old, socially housed rhesus monkeys manipulate objects

More than 10% of the [group-housed] females' time was spent in object [toy] manipulation. ... Socially housed rhesus monkeys ranging in age from 14 to 22 years showed steady rates of object manipulation, and their interest in familiar objects did...

Potential animal hazard with ring toys

Recently one animal, a 2-year-old pigtail macaque (Macaca nemestrina), approximate weight 3.1 kg, became trappedinside a Nylaring. The ring went around the neck, across the body, and under one arm. Since the animal was apparentlyunable to remove the ring, he...

Preference for structural environmental features in captive lowland gorillas (Gorilla gorilla gorilla)*

The results indicate that enclosure usage was significantly associated with the features of slope, nearness to holding facility, and presence of environmental components additional to substrate (e.g., tree or rock). In particular, areas with flat ground that were near the...

Time management by captive ringtail lemurs exposed to a simple foraging design

Although based on an extremely limited sample size, this study suggests that litter-filled containers placed outside of a lemur's cage can provide adequate foraging opportunities.

Enticing nonhuman primates to forage for their standard biscuit ration

Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged in gathering the standard biscuit...

Evaluation of an inexpensive custom-made food puzzle used as primary feeder for pair-housed rhesus macaques

Working for their standard food rather than collecting it from freely accessible food boxes did not impair the [pair-housed] animals' body weight maintenance, suggesting that their general health was not impaired by the new feeding technique.
