abstract = {{Capuchins can employ several strategies to deal with{\textless}br{\textgreater}environmental challenges, such as using stone tools to access{\textless}br{\textgreater}encapsulated resources. Nut-cracking is customary in several{\textless}br{\textgreater}capuchin populations and can be affected by ecological and{\textless}br{\textgreater}cultural factors; however, data on success and efficiency{\textless}br{\textgreater}are only known for two wild populations. In this work,{\textless}br{\textgreater}using camera traps, we assessed palm nut-cracking success{\textless}br{\textgreater}and efficiency in two newly studied wild bearded capuchin{\textless}br{\textgreater}populations (Sapajus libidinosus) and compared them with{\textless}br{\textgreater}other sites. We tested the hypothesis that the overall success{\textless}br{\textgreater}and efficiency of nut-cracking would be similar between sites{\textless}br{\textgreater}when processing similar resources, finding partial support for{\textless}br{\textgreater}it. Although using hammerstones of different sizes, capuchins{\textless}br{\textgreater}had a similar success frequency. However, efficiency (number{\textless}br{\textgreater}of strikes to crack a nut) was different, with one population{\textless}br{\textgreater}being more efficient. We also tested whether success and{\textless}br{\textgreater}efficiency varied between sexes in adults. We predict adult{\textless}br{\textgreater}males would be more successful and efficient when cracking{\textless}br{\textgreater}hard nuts. We found no differences between the sexes in one{\textless}br{\textgreater}site but found sex differences in the other, although also for{\textless}br{\textgreater}the low-resistant nut, which was unexpected. Our data add to{\textless}br{\textgreater}the knowledge of capuchin nut-cracking behaviour flexibility,{\textless}br{\textgreater}variance and potential cultural traits.}},
