The Redwing (Turdus iliacus) included in the Turdinae or True Thrushes, closely resembles the common thrush in its plumage, but is distinguished by the bright red colour of the underwing coverts. It visits Britain as a migratory bird in winter, migrating from more northern regions about the same time as the fieldfares, and departing with or even before them. Redwings congregate in flocks, often associated with fieldfares as jackdaws with rooks, and search the fields for worms and insects or larvae, which, with hawthorn, holly and other berries, comprise their winter fare.
