Behavioral assessment is an essential element of chimpanzee care. Behavioral data were compiled from three chimpanzee laboratory facilities (N=340; 201 females, 139 males) using differing methods of assessment including quantitative data collection, animal records and observations by behavioral management staff. The subject pool contained 46% mother-reared (MR), 41% nursery-reared (NR), and 13% other-reared chimpanzees. Mean group size was 4 (range 2 to 14), 100% had access to outdoor space all year, and 65% had access to a natural substrate. The presence of species-typical chimpanzee behaviors was surveyed: 96% of the subjects used tools to acquire food; 77% built nests; and 73% copulated. Fifty-eight percent of the subjects showed one or more abnormal behaviors; the most common was coprophagy. Ninety-nine percent were reported to generally voluntarily cooperate with requests to shift, 99% show at least one body part for examination, and 72% present for an anesthetic injection. Chi-square analyses revealed NR animals were less likely than MR to use tools (Chi-square = 9.97, p = .007), build nests (Chi-square = 62.51, p = .000), copulate (Chi-square = 45.79, p = .000), and display coprophagy (Chi-square = 11.33, p = .003) or hair-plucking (Chi-square = 8.40, p = .015). This analysis will help guide future improvements in behavioral management to address existing behavioral problems or deficits.
