“…Many species of macaques have been extensively studied in the wild or naturalistic semi-free ranging settings for several years, yielding valuable insights into their behaviour ( Macaca assamensis , Ostner & Schülke, 2018; Macaca fascicularis , Van Noordwijk & Van Schaik, 1985; Macaca fuscata , Nakagawa et al, 2010; Macaca leonina , Albert et al, 2013; Macaca maura , Okamoto et al, 2000 & Riley et al, 2014; Macaca mulatta , Cooper et al, 2022; Macaca nemestrina , Ruppert et al, 2018; Macaca nigra , Duboscq & Micheletta, 2023; Macaca radiata , Sinha, 2005; Macaca sinica , Dittus, 1975; Macaca sylvanus , McFarland & Majolo, 2013; Macaca thibetana , Li et al, 2020). Japanese macaques ( Macaca fuscata ) were one of the first species for which researchers recognised and followed subjects individually, generating unprecedented levels of detail on their behaviour.…”
