Great Black Hawk (Buteogallus urubitinga) Science Article 1
Little is known about the diet or hunting strategies of Great Black-Hawks (Buteogallusurubitinga), a widely distributed but poorly known species in Central and South America.In Panama, Wetmore (Wetmore 1965, p. 231) reported that frogs form a principal food source,and that lizards, particularly basilisks (Basiliscus), also are eaten. In El Salvador Dickey and van Rossem (Dickey & van Rossem 1938) reported finding a grebe, an Inca Dove (Scardafella inca), and an unknown small mammal consumed by Great Black-Hawks. The fo1lowing account of predation by a Great Black-Hawk on nestling Bare-throated Tiger-Herons (Tigrisoma mexicanum) in Costa Rica is one of the first specific reports of predation by this hawk.
