Age-Related Variation in the Mechanical Properties of Foods Processed by Sapajus libidinosus

, 2016
Objectives: The diet of tufted capuchins (Sapajus) is characterized by annual or seasonal incorporation of mechanically protected foods. Reliance on these foods raises questions about the dietary strategies of young individuals that lack strength and ...

Vertebrate Predation and Tool-Aided Capture of Prey by Savannah Wild Capuchin Monkeys (Sapajus libidinosus)

International Journal of Primatology, 2022
Abstract Vertebrate predation was a vital behavior during human evolution. Some non-human primates, such as baboons and chimpanzees, frequently hunt and consume vertebrate prey. Capuchin monkeys (Cebus and Sapajus) are omnivorous neotropical primates, and although vertebrate prey is not their primary food source, they hunt and consume those ...

Nut-cracking success and efficiency in two wild capuchin monkey populations

Royal Society Open Science
Capuchins can employ several strategies to deal with environmental challenges, such as using stone tools to access encapsulated resources. Nut-cracking is customary in several capuchin populations and can be affected by ecological and cultural factors ...
