Heterospizias meridionalis |
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] There are also reports of it in California, from 1973 in Alameda County and from 1974 in San Diego County. [3]
The savanna hawk is 46–61 cm (18–24 in) in length and weighs 845 g (29.8 oz). [4] 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] [4] The legs are yellow. The call is a loud scream keeeeru. [4]
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. [4]
The savanna hawk feeds on small mammals, small birds, lizards, snakes, toads, frogs, eels, other fish, crabs, roots, spiders, and large insects (such as grasshoppers). [5] [6] [7] 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]
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. [4]
