Behavioral Welfare Research for the Management of Sanctuary Chimpanzees

The study at Chimp Haven focused on the behavioral welfare of over 300 sanctuary chimpanzees using various monitoring methods, including wellness surveys, wound tracking, and hair loss assessments. Data from 1456 surveys conducted by 24 observers over 18 months revealed an average wellness score of 1.52, indicating the need for regular quarterly monitoring. Key concerns included abnormal behaviors, coat condition, and wounding, with most wounds being minor. Interventions like additional foraging and positive reinforcement training were used to address issues such as hair loss and compliance with shifting behaviors. The study underscores the importance of continuous, data-driven monitoring and individualized care strategies to enhance the welfare of sanctuary chimpanzees.
