“…The Harpy Eagle (Harpia harpyja; Aves: Accipitridae), the heaviest and most powerful raptor (Brown andAmadon 1968, Voous 1969), inhabits the canopy of Neotropical rainforests (Sick 1997), historically from southern Mexico to northeastern Argentina (Ferguson- Lees and Christie 2001). The diet of the Harpy Eagle has been described for almost all areas of its range, including the Brazilian Atlantic Forest (Aguiar- Silva et al 2012), the Pantanal floodplain (Ubaid et al 2011) and the forest enclaves in the cerrado (central Brazilian woody savanna; Pereira and Salzo 2006) where nesting records are scarce (Silveira et al 2005, Srbek-Araujo and Chiarello 2006, Pereira and Salzo 2006, Aguiar-Silva et al 2012. It feeds mainly on arboreal mammals such as sloths, monkeys, and porcupines (Fowler and Cope 1964, Rettig 1978, Eason 1989, Sanaiotti et al 2001, Touchton et al 2002, Ferrari and Port-Carvalho 2003, Aguiar-Silva 2007, Piana 2007, Benchimol and Venticinque 2010, Lenz and Reis 2011, and less frequently on reptiles and birds (Á lvarez-Cordero 1996, Martínez et al 1996, Touchton et al 2002, Piana 2007, Rotenberg et al 2012.…”
