The interaction between native and exotic species can cause changes both in the food-chain and in aspects of competition for trophic resources, such as predation. Predatory events are common in nature, but difficult and usually recorded opportunistically. Here we present the first report of trophic interaction involving a species of exotic bird (Melopsittacus undulatus) and a species of native primate (Sapajus cay). Capuchin monkeys have already been recorded feeding on a wide variety of vertebrates, including frogs, lizards, birds, mammals, and even other species of primates. Although the record of the non-native M. undulatus in the state of Mato Grosso do Sul indicates a possible domestic escape, the record of predation may represent a beneficial trophic interaction for the ecosystem, preventing M. undulatus from becoming an invasive alien species. Studies are needed to assess what risks are posed by domestic species being preyed upon by native species.
