Estorninho-d'asa-ruiva Onychognathus tristramii

Large, long-winged, and long-tailed starling. In flight, shows large orange wing panels. Males are glossy-black while females are browner overall. Noticeable from a distance by its unique call that often echos off desert wadi cliffs—a clear whistle “tuwheeuwheet.” Often found in small or medium flocks; can be tame and bold. Feeds on fruit, seeds, and arthropods.
