     This study examined whether construction activities (including loud noises, increased numbers of unfamiliar people and novel equipment) occurring in proximity to socially housed chimpanzees impacted their behavior. Over a 24-month period, 192 hours of focal animal data were collected on 18 socially housed chimpanzees (5 males and 13 females; 19-63 years) to identify evidence of disturbance related to the construction. Behavioral data were collected during pre-construction (43 hours), construction (80 hours) and post-construction (69 hours) periods. The incidence of abnormal, anxiety-related, inactivity, self-grooming, social grooming, pro-social and aggressive behaviors showed no changes across study phases, as indicated by a non-significant repeated measures MANOVA (F=4.686; p=0.1). Chimpanzees received standard enrichment for the duration of the construction period, with some adjustment to the temporality of distribution based on construction and noise activity levels. These findings indicate no significant behavioral responses to nearby construction activity, and no evidence that this environmental change was disturbing to the chimpanzees.
