The savanna hawk (Buteogallus meridionalis) is a large raptor found in open savanna and swamp edges. It was formerly placed in the genus Heterospizias. It breeds from Panama and Trinidad south to Bolivia, Uruguay and central Argentina.[2]
Description
The savanna hawk is 46–61 cm (18–24 in) in length and weighs 845 g (29.8 oz).[3] 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.[2][3] The legs are yellow. The call is a loud scream keeeeru.[3]
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 vertically, and its legs are strikingly long.[3]
Food and feeding
The savanna hawk feeds on small mammals, small birds,[4] lizards, snakes, toads, frogs, eels,[4] other fish,[5] crabs, roots,[4] and large insects (such as grasshoppers).[6] It usually sits on an open high perch from which it swoops on its prey, but will also hunt on foot, and several birds may gather at grass fires.[2]
Reproduction
The nest is of sticks lined with grass and built in a palm tree.[2] The clutch is a single white egg, and the young take 6.5 to 7.5 weeks to fledging.[3]
