Chimpanzees are among the most cognitively complex animals in zoo settings, with social rehabilitation of poorly-socialised individuals presenting significant welfare challenges.
Chimpanzee social welfare requires groups that allow natural fission-fusion dynamics within the physical constraints of captivity. Stable core groups with opportunities for subgroup formation provide welfare benefits. Poorly socialised individuals require extended, carefully managed reintroduction programmes. The cognitive sophistication of chimpanzees means that social deprivation causes deep and persistent psychological harm.
