     Behavioral assessment is an essential element of chimpanzee care. Behavioral data were compiled from four chimpanzee laboratory facilities (N=522; 286 females, 236 males) using differing methods of assessment including quantitative data collection, animal records and observations by behavioral management staff. The subjects were 46.4% mother-reared (MR), 46.9% non-mother-reared (NONMR), and 6.7% wild-born (WB). Mean group size was 5.9, 100% had access to outdoor space all year, and 59.2% had daily access to natural substrate. Species-typical behaviors were surveyed: 95.4% used tools to acquire food; 50% built nests; 94.4% initiated grooming; and 68% copulated. Forty-two percent showed abnormal behavior; most commonly stereotypic rocking and coprophagy. Ninety-seven percent generally voluntarily cooperate with requests to shift and 64.2% present for an injection. Chi-square analyses (df = 2) revealed MR chimpanzees were more likely than NONMR to use tools (Chi-square = 16.73, p < .001) and to initiate grooming (Chi-square = 22.59, p < .001). WB were more likely to build nests than MR and MR more likely than NONMR (Chi-square = 82.25, p < .001). MR and WB were more likely than NONMR to copulate (Chi-square = 30.43, p < .001). MR were more likely than NONMR to display coprophagy (Chi-square = 11.74, p = .003). This analysis will help guide future improvements in behavioral management to address existing behavioral problems or deficits.
