“…Guira guira is a South American bird that lives in a wide range of habitats, including urban areas (de la Peña, ), and whose trophic habit is a source of controversy. Although it is widely accepted that G. guira is zoophagous (Bernal de Pereyra, ; Daguerre, ; Payne, ), some authors consider the species to be exclusively insectivorous (Goijman & Zaccagnini, ; Legrand, ; Leveau & Leveau, ), while others note a predilection for vertebrates such as amphibians, reptiles, and small birds (including eggs) (Beltzer, ; Bernal de Pereyra, ; Coutinho, Serra, Junior, & Lima, ; Daguerre, ; Koski & Merçon, ; Morais, Siqueira, & Bastos, ; Payne, ; Repenning, Basso, Rossoni, Krügel, & Fontana, ). Although recent molecular studies suggest an affinity with bustards (Prum et al, ), its phylogenetic relationship with other birds is still the subject of discussion (Hughes, ; Mayr, Manegold, & Johansson, ; Sibley & Ahlquist, ).…”
