Grey Eagle Buzzard ( South America)

The Black-chested Buzzard-Eagle (Geranoaetus melanoleucus) is a bird of prey of the hawk and eagle family (Accipitridae). It lives in open regions of South America. This species is also known as the Black Buzzard-eagle and Grey Buzzard-eagle.

This is a huge eagle-like "buzzard" ("hawk" in American terminology). It has a total length of 24-32 in (about 60–80 cm) and a wingspan of 58-79 in (149–200 cm). In the smaller G. m. australis subspecies, the weight is 3.7-7.1 lb. (1.7-3.2 kg), with no reported weights on the nominate subspecies.

It is noted for its bulky, powerful-looking build. It is rather long- and broad-winged and the slightly tapering tail is short by comparison and coloured black, with grey tips in fresh plumage. When perched, the wings cover the tail almost completely, giving the bird a unique near-tailess appearance when perched. The adult has a white underside, sometimes with fine blackish stripes; its upperparts are dark grey with a blackish, brownish or bluish hue. The feathers of the neck and the lowest dark feathers of the breast are somewhat elongated. Adults have an ash-grey-and-white zone on the wings, the silvery white seen clearly from afar. The female is distinguished by a reddish-cinnamon hue to the upper- and underwing secondaries and is considerably larger than the male.
