There are indications that present methods for the care and management of captive chimpanzees are not fully adequate, particularly from an ecological point of view, resulting in a physiological and especially psychological condition of the animals which is below optimal. In contrast to what is reported from the wild, many captive animals become apathic and dull, indulge in stereotypic behavior patterns and become very aggressive and unpredictable as they get older. The fact that the present reproduction rate in captivity appears much too low to make a continuous importation from the wild unnecessary was also regarded as significant in connection with the conditions of captive chimpanzees. These points and their causes as well as possibilities for improvement are discussed.
