: Our study was purely observational and noninvasive. Researchers followed a strict hygiene protocol (Gilardi et al.CitationRef removed). Researchers quarantine for 5 days before following the chimpanzees. During follows, researchers disinfect their hands before entering the forest, wear face masks, and keep a minimum distance of 8 m between themselves and the chimpanzees, to avoid disease transmission from humans to chimpanzees and to not disturb the natural behavior of the observed individuals. Research protocols adhered to the legal requirements of Gabon and followed the recommendations of the Animals (Scientific Procedures) Act 1986, as published by the government of the United Kingdom. The research also followed the principles of "Ethical Treatment of Non-Human Primates" as stated by the American Society of Primatologists. The Agence Nationale des Parcs Nationaux, and the Centre National de la Recherche Scientifique et Technique of Gabon, Libreville, Gabon granted permission to carry out research at Loango National Park.
