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]

The golden-headed manakin is a small passerine bird which breeds in tropical Central and South America in both wet and dry forests, secondary growth and plantations. It is a small manakin, about 9.4 centimetres (3.7 in) long. Males are entirely black apart from a golden head, yellow bill, white and red thighs and pink legs. Females and juveniles are olive-green with pink legs. At breeding time, males are involved in a cooperative lekking behaviour during which they jump, slide and dart from perch to perch. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The pearl kite is a very small raptor found in open savanna habitat adjacent to deciduous woodland. It is the only member of the genus Gampsonyx. The scientific name commemorates the English naturalist William Swainson.

Buteogallus daggetti, occasionally called "Daggett's eagle" or the "walking eagle", is an extinct species of long-legged hawk which lived in southwest North America during the Pleistocene. Initially believed to be some sort of carrion-eating eagle, it was for some time placed in the distinct genus Wetmoregyps, named for Alexander Wetmore. It probably resembled a larger version of the modern-day savanna hawk, with its long legs possibly used like the secretarybird of Africa to hunt for small reptiles from a safe distance. It died out about 13,000 years ago.
The common black hawk is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and vultures.
