Effects of selected behavioral enrichment devices on behavior of western lowland gorillas (Gorilla gorilla gorilla)

Devices used included cardboard boxes containing food items [and straw], paper bags containing food items [and straw], burlap rags [containing straw], and willow and maple browse. The enrichment devices increased foraging, social play, and solitary play behaviors [in group-housed animals]...

Discussion: A plea for pair-housing of adult macaques

Practical implications of several attempts of pair formation and subsequent permanent pair-housing protocols of previously single-caged adult macaques are discussed. Of 165 pairs reported, 97% were compatible during pair formation.

The effect of duration of individual housing on social behavior of adult male bonnet macaques (Macaca radiata)

Already familiar adult male bonnet macaques were moved from one-month, and 24-month temporary single-housing to pair- and trio-housing situations. The males were only given the opportunity for social integration [in a playpen] one day [for four hours] each day. ......
