105Novak MA, Kinsey JH, Jorgensen MJ, Hazen TJ 1998. Effects of puzzle feeders on pathologicalbehavior in i<strong>nd</strong>ividually housed rhesus monkeys. American Journal of <strong>Prima</strong>tology 46, 213-227"Manipulation of the puzzle feeder was associated with a reduction in pacing a<strong>nd</strong> rocking in allsubjects; but this effect was transient, occurring only during the first hour after the puzzle feederwas filled with treats. Puzzle feeder manipulation had no effect on self-injurious behavior.”Nishimura S 2006. Owl monkey enrich<strong>ment</strong> ideas. Tech Talk 11(1)"One enrich<strong>ment</strong> item we use is a small suet basket. We place pieces of fresh fruits, dried fruits,nuts, a<strong>nd</strong> ice cubes inside the basket a<strong>nd</strong> hang it inside the cages a<strong>nd</strong> kennels. The holes in thesuet basket are too small <strong>for</strong> the Aotus to reach through, so they spe<strong>nd</strong> a good amount of timetrying to manipulate the food pieces with their fingers a<strong>nd</strong> teeth.Another <strong>for</strong>m of enrich<strong>ment</strong> used is a small plastic baskets filled with hay, pine shavings, or SaniChips to which we add a few nuts, cereal pieces, or mealworms." These two items increase<strong>for</strong>aging time.O'Connor E, <strong>Re</strong>inhardt V 1994. Caged stumptailed macaques voluntarily work <strong>for</strong> ordinary food.In Touch 1(1), 10-11http://www.awionline.org/Lab_animals/biblio/tou-food.htm"Dan spent 286 seco<strong>nd</strong>s retrieving 12 biscuits from the food puzzle after leaving 21 freelyavailable dish-biscuits untouched."Perret K, Büchner S, Adler HJ 1998. Beschäftigungsprogramme für Schimpansen (Pantroglodytes) im Zoo. Der Zoologische Garten 68, 95-111An effective feeding enrich<strong>ment</strong> program <strong>for</strong> group-housed chimpanzees is described a<strong>nd</strong>assessed. The program resulted in a more than two-fold increase in time spent <strong>for</strong>aging (23.6%vs. 57.4% per day).Poffe A, Melotto S, Gerrard PA 1995. Comparison of four environ<strong>ment</strong>al enrich<strong>ment</strong> strategiesin captive common marmosets (Callithrix jacchus). <strong>Prima</strong>te <strong>Re</strong>port 42, 24-25"Access to the puzzles was accompanied by increase in social interaction a<strong>nd</strong> activity a<strong>nd</strong>decrease in stereotypic behaviour. This behavioural profile was also observed, to a lesser extent,in animals exposed to the 'gum tree'. ... Novel objects alone [toys] failed to significantly alterbehaviour."Preilowski B, <strong>Re</strong>ger M, <strong>En</strong>gele H 1988. Combining scientific experi<strong>ment</strong>ation with conventionalhousing: A pilot study with rhesus monkeys. American Journal of <strong>Prima</strong>tology 14, 223-234"The testing apparatus ... was connected to a computer that controlled the test a<strong>nd</strong> thedistribution of regular monkey chow as reward." Manipulatory activity required by theapparatus reduced motor stereotypies but not self-biting in single-housed subjects.Prist. P., Pizzutto CS, Hashimoto C 2004. Woven vine balls a<strong>nd</strong> baskets as feeding enrich<strong>ment</strong><strong>for</strong> howler monkeys. Shape of <strong>En</strong>rich<strong>ment</strong> 14(2), 1-2http://www.enrich<strong>ment</strong>.org/articles/142Howlers.pdf"Our results showed that the animals spent more time <strong>for</strong>aging when the feeder balls were used[compared to the baskets], since it was more difficult to reach the leaves. The monkeys alsoexplored each of the baskets a<strong>nd</strong> stopped spe<strong>nd</strong>ing most of their time on the floor. We concludedthat these two enrich<strong>ment</strong> ideas increased the animals' activity through play a<strong>nd</strong> exploration,a<strong>nd</strong> also increased their use of vertical space a<strong>nd</strong> reduced their time on the floor. Thesebehaviors are more species-typical a<strong>nd</strong> appropriate <strong>for</strong> arboreal monkeys."
