The Behavioral Effects Of Feeding Enrichment On A Zoo-Housed Herd Of African Elephants (Loxodonta Africana), Caroline Marie Driscoll
The Behavioral Effects Of Feeding Enrichment On A Zoo-Housed Herd Of African Elephants (Loxodonta Africana), Caroline Marie Driscoll
Graduate Theses
A comprehensive study on the behavioral effects of feeding enrichment was conducted on six African elephants housed at the North Carolina Zoological Park in Asheboro, NC. The herd is comprised of are two adult males, three adult females, and one subadult female. The study was conducted over a 10-month period and consisted of focal sample observations across three conditions. Observations were recorded during the baseline condition (June to September) and continued through the introduction of feeding enrichment. Behavioral data were also collected when enrichment items were present but food presentation followed the historical husbandry routine, known as the experimental control …
Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald
Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald
All Master's Theses
Captive chimpanzees (Pan troglodytes) engage with enrichment objects extensively during the daytime, yet relatively little is known regarding their use of available enrichment at night. This study examined night-time enrichment use in three adult chimpanzees at the Chimpanzee and Human Communication Institute. Every evening, the chimpanzees received a variety of enrichment objects. The objects belonged to one of nine categories. Night-vision video cameras recorded the chimpanzees’ night-time behaviors every Monday through Thursday from July 9 to August 9, 2012 (Carner et al., 2013). The present study used a focal animal, instantaneous sampling method (Martin & Bateson, 2007) to …
Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia
All Master's Theses
Enrichment is an aspect of captive husbandry that has been shown to positively impact animals’ well-being and can be designed to encourage species-typical behaviors, such as foraging and arboreality. Enrichment can include housing together multiple compatible species. Orangutans are sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two Sumatran (Pongo abelii) and two Bornean (P. pygmaeus) orangutans with …
