Resumo: | This study aimed to analyze the effects of dietary environmental enrichment on the behavior of black-eared opossums that were in captivity at the Brazilian Wild Animal Screening Center (CETAS-ES), in the municipality of Serra-ES, Brazil, from August to October 2022. Two food models were constructed for the study: the “Surprise Tubes” and the “Food Puzzle”. A total of 24 juvenile black-eared opossums were selected, regardless of sex, and divided into eight groups, with three animals each. Then, four groups were exposed to one model and four to the other. Each group was subjected to two conditions: experimental, with the presence of the models, and control, without the presence of the models. Each condition lasted 24h and occurred on two consecutive days. They were filmed with a camera trap, resulting in 3,233 videos of 25s. To construct the ethogram, 24 videos of each group were selected, which were recorded from 18h to 19h:30, when the animals were more active. The opossums interacted with both models, accessing, and eating the hidden food, preferring meat over fruit. No significant differences were found in the behavior of opossums regarding the models, and the aggressive behavior significantly decreased when the models were present. It is concluded that the models can be used as an environmental enrichment for black-eared opossums, reducing aggressive behavior.Palavras-chave: Didelphis aurita; cativeiro; marsupial |

Dois modelos alimentares foram construídos para o estudo: os “Tubos Surpresa” e o “Quebra-Cabeça Alimentar”. Foram selecionados 24 gambás-de-orelha-preta, independente do sexo, juvenis, divididos em oito grupos, com três animais cada, sendo quatro grupos expostos a um modelo e quatro ao outro. Cada grupo foi submetido a duas condições: experimental, com a presença do modelo e controle, sem a presença do modelo. Cada condição durou 24 horas e ocorreram em dois dias consecutivos. Foram filmadas com câmera trap, resultando em 3233 vídeos, de 25 segundos cada. Para elaboração do etograma foram selecionados 24 vídeos de cada grupo, gravados entre as 18h00 e 19h30hs, período em que os animais se mostraram mais ativos. Os gambás interagiram com os dois modelos, acessando e comendo os alimentos escondidos, havendo preferência pela carne em comparação com a fruta. Não houve diferença significativa no comportamento dos gambás em relação aos modelos e observou-se que o comportamento agressivo diminuiu significativamente quando os modelos estavam presentes. Conclui-se que os modelos podem ser utilizados como enriquecimento ambiental para os gambás-de-orelha-preta, trazendo benefícios para a diminuição do comportamento agressivo.
