Guira guira, a member of the subfamily Crotophaginae, is widely distributed across South America, occurring in countries such as Brazil, Bolivia, Paraguay, Uruguay and Argentina. Its diet is primarily carnivorous, consisting mainly of arthropods, particularly those from the order Orthoptera, though occasional predation on small vertebrates has also been recorded. The consumption of anurans by G. guira is considered infrequent, with rare and often imprecise records of prey identification. This study documents various anurans and reptiles species consumed by G. guira, as along with the the capture strategies employed. Observations were conducted in a rural of Corumbá, MS, in the southern Pantanal region, specifically in the Pantanal do Paiaguás, in northern Mato Grosso do Sul. A total of seven anurans species and one lizard species were recorded, with most of the consumed individuals being males. The findings expands the list of prey associated with G. guira and provides valuable information into its foraging behavior and hunting techniques, particularly during the parental care period.
