: We have complied with all relevant ethical regulations for animal use. This study is purely observational and non-invasive, and has been approved by the Ethikrat der Max Planck Gesellschaft (04/08/2014). At the Taï Chimpanzee Project we follow the IUCN best practice guidelines for health monitoring and disease control in great apes, including rigid hygiene rules, wearing a surgical mask while following the chimpanzees and keeping 7 m distance. In addition, we employ a 5 day quarantine before observing the chimpanzees to protect their health.
