Chimpanzees in zoos face profound welfare challenges because their complex social, cognitive, and physical needs are difficult to meet in captivity, leading to behavioral abnormalities and psychological suffering.
Chimpanzees may be the most cognitively sophisticated animals regularly held in zoos, making their welfare needs among the most demanding to meet. The gap between wild chimpanzee complexity and captive provision is enormous. Psychological suffering from social deprivation, boredom, and inability to express natural behaviors manifests as behavioral abnormalities that persist even with improved housing. Accredited zoos have made significant welfare improvements, but fundamental constraints remain inherent to captivity for highly intelligent, wide-ranging primates.
