Aprendizado de Sapajus apella (Primates: Cebidae) em cativeiro: predação de crustáceos

Abstract

The present work aimed to study the learning capacity of Sapajus apella young specimens for the expression of predation behavior through the observation of the action of adult specimens. The study is justified by the need to elaborate rehabilitation protocols for the species involving the formation of stable groups for monitored release. The work was carried out in the building of Primates of IBAMA/CETAS of São Luis, located in the Forest Garden of IBAMA. The study involved eight specimens of Sapajus apella, four tutors and four apprentices, in six evaluation phases. Young prey monkeys showed learning ability, demonstrated by the consumption of a new food item from the learning with another experienced specimen. However, many variables interfere in this learning process, especially age, previous experience and predation ability.
