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. The male of this 27–30-centimetre (11–12 in) long starling has mainly iridescent black plumage, with chestnut flight feathers, which are particularly noticeable in flight. The female has an ash-grey head and upper breast. The juvenile resembles the male, but is less glossy than the adults, and has brown rather than dark red eyes. The Ethiopian subspecies O. m. rupellii is longer-tailed than the nominate form and intergrades with it. This species has a number of whistled calls, but the most familiar is the contact call, cher-leeeoo. (Source: Wikipedia.org, CC BY-SA)
