Chimp platforms in outdoor enclosure

A project was initiated to take advantage of the vertical space by building a wooden platform with two decks in each of the eight corrals. The platforms have been used by chimpanzees of all ages, and have been the center...

Challenges of forming a new gorilla group

This paper will address the challenges, expected and unexpected, that were encountered during the introductions of these three gorillas. We have tracked these introductions along with some of the rationale for decisions based on each gorilla's history, personality, individual responses...

A naturalistic exhibit’s biological success

All in all, the exhibit has exceeded expectations. The plants are bigger and have expanded their range. Native plants have reestablished themselves without harmful effects, and native fauna add an extra dimension to gorilla enrichment. No data are included in...

Preferences for food location and foraging requirements in white-handed gibbons

Mixing ice with the food [in buckets] reduced eating time slightly but substantially increased foraging time. Foraging was much more extensive from the top bucket and significantly more food was gathered from this source than from the bottom bucket. The...

Chimpanzees in single cages and small social groups: Effects of housing on behavior

Chimpanzees housed in pairs or trios showed fewer signs of tension, anxiety and aggressiveness than those housed singly. However, providing one or two social companions did not appear to ameliorate abnormal behavior over the long term.

Effects of enriched food acquisition on activity budgets of two tamarin species at Adelaide Zoo

Simple bamboo pipe feeder is described and tested in group-housed animals. The aim of the study was to [successfully] increase foraging time with an increasing number of feeding devices [brawn bowl, bamboo pipe]. ... Prior to the study large amounts...

The neighbor effect: Other groups influence intragroup agonistic behavior in captive chimpanzees

Hearing the vocalizations of neighboring groups increased the likelihood of intragroup fighting. It may be indicated to construct corrals at a distance from each other to avoid this undesirable neighbor effect.

The use of operant conditioning to facilitate the introduction of drill baboons (Papio leucophaeus)

A previously single-housed male drill was paired with another female. Although baboons are normally a social species, we have observed little physical contact between Ace and Rosie. Neither have we observed any aggression between the two. The two animals spend...
