Kleptoparasitism has been extensively described for raptors and seabirds, but there are fewer observations for passerine birds. Here we describe several events of interspecific kleptoparasitism in the Great Kiskadee (Tyrannidae: Pitangus sulphuratus) in Buenos Aires, Argentina. Although interspecific kleptoparasitism has not been described previously for this species, we believe this foraging strategy is more common than expected for a passerine bird. The observations described in this paper are consistent with four of the six ecological conditions proposed by Brockmann and Barnard (1979).
