On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator, Using the Giraffe (Glraffa Camelopardalis) as a Model

To assess the validity of using wild behavioural data as a welfare indicator for zoo animals, the time budgets of 19 captive giraffe (Giraffa camelopardalis), from four zoos were compared with the time budgets of wild giraffe from Hwange National Park, Zimbabwe. Differences were shown to exist between the behaviour of wild and captive giraffe. […]

On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator

It is commonly assumed that animals suffer if they cannot perform behaviours seen in wild conspecifics. Although comparisons with the behaviour of wild conspecifics are a popular method of assessing the welfare of captive animals, their validity has not been fully assessed. Homeostatic models of motivation suggest that many behaviours are stimulus driven rather than […]

Catching the Spirit: A Study of Bureau of Land Management Wild Horse Adopters in New England

Between 1971 and 2009, the U.S. Bureau of Land Management (BLM) adopted out nearly 225,000 horses and burros in the wild (wild horses and burro) who were removed from public lands (BLM, 2009). The inability of the BLM to adopt out wild horses as quickly as they are removed and recurring reports that many wild […]

Behavioral and Hormonal Consequences of Transporting Giant Pandas From China to the United States

Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress responses. An extensive literature exists concerning the animal welfare implications of road transportation […]

Behavioral effects of an immunocontraceptive vaccine on eastern fox squirrels

Managing pest species in urban and suburban areas is challenging, and contraception may provide a socially acceptable and effective management option for many species. The immunocontraceptive vaccine, GonaCon, effectively inhibits reproduction in many species of wildlife, but the behavioral effects are not yet well understood. Contraceptive-induced changes in behavior could raise animal welfare concerns and […]

Ultrasonographic adrenal gland findings in healthy semi-captive cheetahs (Acinonyx jubatus)

Cheetahs in captivity are believed to suffer from stress predisposing them to poor health. To date fecal glucocorticoids have been used as a non-invasive indicator of chronic stress. This study examines, the feasibility of transabdominal adrenal gland ultrasonography in cheetahs and determined normal adrenal measurements that can potentially be used as a more reliable indicator […]

Daily travel distances of zoo-housed chimpanzees and gorillas: implications for welfare assessments and space requirements

The degree to which the relatively smaller area of artificial environments (compared with natural habitats) has measureable effects on the behavior and welfare of captive animals has been debated for many years. While there is little question that these spaces provide far less opportunity for natural ranging behavior and travel, less is known about the […]
