The Savanna Hawk (Buteogallus meridionalis) is a large raptor found in open savanna and swamp edges, with a wide range that extends from Panama and Trinidad in the north to Bolivia, Uruguay and central Argentina to the south.
The savanna hawk is 46–61 cm in length and weighs 845 g. The adult has a rufous body with grey mottling above and fine black barring below. The flight feathers of the long broad wings are black, and the tail is banded black and white. The legs are yellow. The call is a loud scream keeeeru.
Immature birds are similar to the adults but have darker, duller upperparts, paler underparts with coarser barring, and a whitish supercilium. This species perches very horizontally, and its legs are strikingly long.
These initial images were taken at the Parque Cóndor, a rescue and release bird park and sanctuary near Otavalo, Ecuador; these birds were in an aviary clearly marked ‘Savanna Hawk’ but after reading descriptions from several sources, I’m wondering if these are in fact Savanna Hawks. Young or immature, perhaps?
