Resumo
The observation of parents feeding a captive fledgling of Great Kiskadee revealed that visitation is more frequent in the first hour after sunrising, with lesscr peaks along the day. The diet supplied consisted mainly of insects (Hymenoptera, Lepidoptera, Coleoptera, Diptera), along with other items as human-made materiais (food scraps, pellets of animal food), lizards (Hemidactylus mabouia), non-identified fruit pulp, gastropods and arachnids (Opiliones). The ability that P. sulphuratus has for identifying food items absent froni more natural habitats and for exploiting resources of unpredictablc spatial and temporal distributions confers the species a dietary flexibility that probably contributes to its efficiency in colonizing urban habitats.

The ability that P. sulphuratus has for identifying food items absent froni more natural habitats and for exploiting resources of unpredictablc spatial and temporal distributions confers the species a dietary flexibility that probably contributes to its efficiency in colonizing urban habitats.
