The red-winged starling (Onychognathus morio) is a bird of the starling family Sturnidae native to eastern Africa from Ethiopia to the Cape in South Africa. An omnivorous, generalist species, it prefers cliffs and mountainous areas for nesting, and has moved into cities and towns due to similarity to its original habitat. It may be found in forest, savannah, grassland, wetlands, fynbos, farmlands and commercial plantations, as well as urban centres. It is now common in many urban areas, due to the similarity between the structure of tall buildings and houses as nest sites with the cliffs of its original habitat. It may also nest in residential areas, breeding in roofs and apertures and up house eaves.
Like other starlings, the red-winged starling is an omnivore, taking a wide range of seeds, berries, nectar from plants such as Aloe and Schotia brachypetala, and invertebrates, such as the beetle species Pachnoda sinuata. They may take nestlings and adults of certain bird species, such as the African palm swift. It will also scavenge on carrion and human food scrap.
