A large glossy-black starling with a wedge-shaped tail and brick-red windows in the wings that are striking in flight. The male and female have black and gray heads respectively. Pairs and flocks prefer rocky outcrops, cliffs, and gorges, within the savanna zone. Similar to Chestnut-winged Starling, but found in different habitat, and separated by being chunkier, with a much heavier bill and broader tail. The vocalizations are characteristic loud liquid oriole-like contact calls and other musical whistles and warbles.
