The species Alouatta belzebulis a primate that showa disjointed population. Besides the great part of the population in the Amazon Forest biome, the small part is distributedin the Northeastern of Brazil, in the Atlantic Forest biome, in the states of Rio Grande do Norte, Piauí, Pernambuco, Paraíba and Alagoas.The species is currentlyincludedin the international red list, at“vulnerable"category. This study had theobjectivetomonitoredthe captive behavior of two individualsof the Alouatta belzebulspecies,focusing the pairingthrough environmental enrichment techniques in the Recife’s Zoo. Both weremonitored along fivedays a week for two hours aday,using the observational methods of focal sampling for two minutes and three minutes of time interval. Behavior pattern acronyms were based in an ethogram built at the beginning of the research.The data analysis was performed through the frequency and duration of the behavioral patterns of each individual, generating dataof the use of space, activitybudget and social interactions. It was observed that the individual category wasmore frequent than the other categories, social and stereotype. Stereotyped behaviors were documented in both animals. Social interactions were found exclusively for affiliative interactions. Following the behavioral protocols of the National Action Plan for the Conservation of Northeast’s Primates, no one animalwas able to survive if released in nature without a broad preparation to improve physical and psychological aspects
