text: The Southern Hemisphere has the black swan (Australia) and two pink-legged forms (South America): the black-necked swan (C. melancoryphus), an especially bad-tempered but beautiful bird, with white body, black neck and head, and prominent red caruncle (fleshy outgrowth) on the bill; and the coscoroba (Coscoroba coscoroba), an all-white bird that is usually considered the smallest swan but may have affinities with the whistling duck.
