Abstract

Invasive exotic species can negatively impact local biodiversity. We present here a report of a nest predation of an endemic bird species, variable oriole (Icterus pyrrhopterus) by the introduced black-tufted marmoset (Callithrix penicillata) in an agricultural landscape highly disturbed by human activities. Two nestlings were predated, by adults of the introduced marmoset during two alternate days. Antipredator behavior and vocal mimicry were observed in variable oriole, while copulation was observed in black-tufted marmoset during the predation. The use of mobbing against predators by I. pyrrhopterus was observed and it is described here by the first time. The potential impact of the introduced marmosets to local biodiversity is discussed.Espécies exóticas invasoras podem impactar negativamente a biodiversidade de um local. Nós descrevemos aqui um relato de predação a um ninho de uma espécie de ave endêmica, inhapim (Icterus pyrrhopterus) pelo sagüi-de-tufo-preto (Callithrix penicillata), espécie exótica invasora, em uma paisagem agrícola altamente impactada pelas atividades humanas. Dois ninhegos foram predados por adultos de sagüi em dois dias alternados. Durante a predação foram observados comportamento anti-predatório e imitações vocais pelo inhapim, e atividade de cópula do sagüis-de-tufo-preto. Descrevemos também o primeiro relato do uso de mobbing por I. pyrrhopterus contra predadores. O impacto potencial dos sagüis introduzidos na biodiversidade local é discutido.
