The Red-backed Hawk (Buteo polyosoma) is found in the Falklands and in South America. All adults have grey upper-wings, but only the males have grey backs, the females being distinguished by their chestnut backs. There are light and dark variations in both sexes, but this should not confuse identification. Favourite nesting sites are rocky outcrops and low cliffs, with nests being made from twigs and vegetation. The nests are re-used each year, although a pair may hold two or three nests within their territory from which to choose.
