ZAFFIGNANI, Daniela  and  PALACIO, Facundo X.. TROPICAL KINGBIRD (TYRANNUS MELANCHOLICUS) FEEDING A FLEDGLING WITH BLUE PASSIONFLOWER (PASSIFLORA CAERULEA) FRUIT. Hornero [online]. 2021, vol.36, n.1, pp.81-90. ISSN 0073-3407.

The Tropical Kingbird (Tyrannus melancholichus) feeds mostly on flying insects, but it can also supply its diet with other arthropods, fruits, and even small vertebrates. Despite being one of the most common birds in the Neotropics, knowledge about its foraging behavior is scarce. In December 2020, we observed and vide- otaped an adult feeding a fledgling with pulp and seeds of Blue Passionflower (Passiflora caerulea) in Ranchos, northeastern Buenos Aires province, Argentina. The whole event lasted 3:37 min. This is the first time that this foraging and breeding behavior is reported for the Tropical Kingbird.

Keywords : frugivory; Ranchos; seed dispersal; Tyrannidae.
