Review of the rescue, rehabilitation and restoration of oiled seabirds in South Africa, especially African penguins Spheniscus demersus and Cape gannets Morus capensis, 1983-2005

South Africa is a global hotspot for oil pollution. The regional oiled seabird cleaning centre, the South African Foundation for the Conservation of Coastal Birds (SANCCOB), has handled over 50 000 seabirds from its inception in 1968 until 2005. The majority of seabirds oiled in South Africa are African penguins Spheniscus demersus, followed by Cape […]

Unusual behaviour of captive-raised gibbons: implications for welfare

Unusual behaviours not normally seen in the wild were studied in 52 captive agile (Hylobates agilis albibarbis) and 23 Mu¨ llers gibbons (H. muelleri spp) at three locations within the Kalaweit Gibbon Rehabilitation Project. Unusual behaviours included stereotypic behaviour (SB), human-directed masturbation and posterior presenting. These data were collected over 18 months as part of […]

Strike-induced chemosensory searching (SICS) in northern Pacific rattlesnakes (Crotalus viridis oreganus, Holbrook, 1840) rescued from substandard husbandry conditions. II. Complete recovery of function after two years

Abstract 10.1002/(SICI)1098-2361(1999)18:23.3.CO;2-J Six northern Pacific rattlesnakes (Crotalus viridis oreganus) rescued from substandard husbandry conditions were shipped from Woodland Park Zoological Gardens to the University of Colorado in December 1994. The snakes accepted prey and rapidly gained weight, but their searching behavior after predatory strikes was seriously depressed. We administered repeated tests of strike-induced chemosensory searching […]

Annual intake trends of a large urban animal rehabilitation centre in South Africa: a case study

Each year, worldwide, large numbers of wild animals are taken to rehabilitation centres for treatment, care and release. Although analysis of intake records may provide valuable insight into the threats and impacts to wildlife, there are few such published reports. Four years of intake records from a large urban rehabilitation centre in South Africa were […]

Rehabilitation of research chimpanzees: Stress and coping after long-term isolation

We report on the permanent retirement of chimpanzees from biomedical research and on resocialization after long-term social isolation. Our aim was to investigate to what extent behavioral and endocrine measures of stress in deprived laboratory chimpanzees can be improved by a more species-typical social life style. Personality in terms of novelty responses, social dominance after […]

Ethics of Interventions for the Welfare of Free-living Wild Animals

There is growing interest in and support for the development of disease prevention measures in free-living wildlife and for the rescue, treatment and rehabilitation of wild animals that are sick and injured. In some cases these endeavours may be of importance to the conservation of populations but frequently they are undertaken for welfare rather than […]

Post-release survival of hand-reared tawny owls (Strix aluco) based on radio-tracking and leg-band return data

The post-release survival of hand-reared tawny owls (Strix aluco) was measured using radio-tracking and leg-band return data. Of 16 birds fitted with 2.4 g radiotelemetry tags, two shed their tags after four and nine days, respectively and one bird was recovered and the tag removed. The remaining 13 birds were tracked for between 16 and […]

Factors that can be used to predict release rates for wildlife casualties

Of the wildlife casualties admitted to rehabilitation centres in England, less than half are subsequently released back into the wild. If the factors associated with survival within rehabilitation centres can be determined, they may be used to focus efforts on individuals with high chances of successful recovery, and thus improve welfare by devoting resources to […]

A Study of Rehabilitated Juvenile Hedgehogs After Release into the Wild

Many juvenile hedgehogs (Erinaceus europaeus) are ‘rehabilitated’ with little or no previous experience of life in the wild. A study is described in which twelve such animals were monitored after release in Devon. They quickly learned their way about, built nests and found them again, and interacted normally with each other and with wild conspecifics. […]

The Survival and Welfare of Hedgehogs (Erinaceus europaeus) After Release Back into the Wild

The fate of rescued hedgehogs (Erinaceus europaeus) released back to the wild has now been the subject of several follow-up studies. Although subject to various hazards, released hedgehogs have clearly shown essential ‘life-skills’. However, all previous studies have involved releases into hedgehog-rich areas and the observed long-range (≥500m) dispersal movements shown by some subjects, of […]
