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".
Migrating and wintering birds often form loose flocks of 10 to 200 or more birds, often feeding together with fieldfares, common blackbirds, and starlings, sometimes also with mistle thrushes, song thrushes, and ring ouzels. Unlike the song thrush, the more nomadic redwing does not tend to return regularly to the same wintering areas.
It breeds in conifer and birch forest and tundra. Redwings nest in shrubs or on the ground, laying four to six eggs in a neat nest.
It is omnivorous, eating a wide range of insects and earthworms all year, supplemented by berries in autumn and winter.
