The hand rearing, development and reintegration of a neurologically ill male Sumatran orang-utan Pongo pygmaeus abelii at the Jersey Wildlife Preservation Trust

An account is given of the hand rearing, development and reintegration of a n infant Sumatran orang-utan Pongo pygmaeus abelii living at the Jersey Wil dlife Preservation Trust, who was removed from his mother due to neurologic al problems between the ages of 264 and 353 days, Information relating to h is health, diet, housing and development during this period is given. In or der to describe how the infant interacted and behaved once recovered and re introduced to his mother and the other orang-utans, behavioural observation s were made during the first year of reintegration. These showed that the i nfant became more confident in initiating social interactions with other or angutans and behaved in a similar manner to orang-utans of a similar age bo th in the wild and in captivity. Information on the hand rearing and integr ation of both sick and healthy infants provides valuable guidance not only for toes but also for in situ rehabilitation centres attempting to reintrod uce this endangered species to the wild.
