Promoting species typical behavior in Coquerel’s sifakas (Propithecus Verreauxi Coquereli)

The sifakas rarely were observed on the ground, preferring to locomote on vertical substrates and rest on vertical and horizontal elevated substrates in all four size categories. Therefore, if vertical surfaces were absent from captive habitats, these rare lemurs could...

Placing hand-reared chimpanzees (Pan troglodytes) into adult social groups: A technique for facilitating group integration

A successful group integration protocol of two hand-reared, 2 and 2.5 years old chimpanzees into a adult mixed-sex group is described. This study suggests that prior housing with socially experienced adult females can facilitate the integration of hand-reared infants into...

A comparative study of a group of colobus monkeys Colobus guereza matschiei before and after enrichment of their captive environment

The effect of the enrichment devices [barklitter, branches, basket filled with 'goodies', etc.] applied on the colobus exhibit could be seen both in a totally higher score for 'activity' [29.3%], and a higher amount of social interactions [16.5%].

Enrichment of a blind monkey

The [blind] male was more interested in 'finishing the puzzle' than eating the food in it. He often dropped the food he retrieved on the ground and ate it later. ... It may take a little more thought to create...

Planting trees in an outdoor compound of chimpanzees for an enriched environment

We have been planting trees of different species in this compound for environmental enrichment since 1993. ... Presently, most of the trees planted are still growing well. ... Grasses also grew naturally in the compound and chimpanzees spent about 90%...
