The redwing (Turdus iliacus) is a bird in the thrush family Turdidae, native to Europe and Asia, slightly smaller than the related song thrush. This species was first described by Linnaeus in his Systema naturae in 1758 under its current scientific name. The English name derives from the bird's red underwing. It is not closely related to the red-winged blackbird, a North American species sometimes nicknamed "redwing", which is an icterid, not a thrush. The binomial name derives from the Latin words turdus, "thrush", and ile "flank". It is 20–24 cm long with a wingspan of 33–34.5 cm and a weight of 50–75 g. The sexes are similar, with plain brown backs and with dark brown spots on the white underparts. The most striking identification features are the red flanks and underwing, and the creamy white stripe above the eye. Related clips:
