Environmental effects on the behavior of zoo-housed lions and tigers, with a case study of the effects of a visual barrier on pacing

Tigers and lions in the wild are nocturnal nonhuman animals who may hunt and mate opportunistically during daylight hours. In captivity, they spend most time on exhibit sleeping or pacing. To better understand their activity budget, this study examined the daily behavior patterns of 2 Sumatran tigers and 3 African lions in different housings. The […]

Environmental Enrichment for Australian Mammals

Many of Australia’s nocturnal mammals are rare or endangered in the wild. The behavioural integrity of captive populations of endangered species can be maintained through the application of environmental enrichment techniques. This study investigated the effectiveness of feeding enrichment in promoting behavioural diversity, enclosure usage and species-typical behaviours in the ghost bat (Macroderma gigas) and […]

Improving diet and activity of insectivorous primates in captivity: Naturalizing the diet of Northern Ceylon gray slender loris, Loris lydekkerianus nordicus

Data on in-situ diet and nutritional requirements should inform the provision of food to captive insectivorous primates. Despite the growing availability of such information an over-reliance on commercially available primate foods and fruit continues in many captive establishments. Wild slender lorises are almost exclusively insectivorous, yet captive conspecifics are fed a primarily frugivorous diet that […]

Nocturnal behavior in captive giraffe (Giraffa camelopardalis)—A pilot study

Captive giraffes (Giraffa camelopardalis) are known to perform oral and locomotor stereotypies. However, many studies do not consider the behavioral repertoire of these animals during the time when animals are confined to night quarters. At two zoological institutions, a total of six captive giraffes were observed via camera trap technology throughout six diurnal and nocturnal […]
