The Fieldfare (Turdus pilaris) is a member of the thrush family Turdidae. Its English name, dating back to at least the twelfth century, derives from the Anglo-Saxon feld-fere meaning “traveller through the fields”, probably from their constantly moving, foraging habits.
It breeds in woodland and scrub in northern Europe and Asia. It is strongly migratory, with many northern birds moving south during the winter. It is a very rare breeder in Great Britain and Ireland, but winters in large numbers in these countries.
It nests in trees, laying several eggs in a neat nest. Unusually for a thrush, they often nest in small colonies, possibly for protection from large crows. Migrating birds and wintering birds often form large flocks, often with Redwings.
It is omnivorous, eating a wide range of insects and earthworms in summer, and berries in winter. (wikipedia)
