From the end of October they may be seen foraging in open country in large flocks. They feed mainly on worms, berries and fruit. Although our visitors come mainly from Iceland, redwings also fly here from Scandinavia and Northern Europe. They have flexible itineraries; some may stay for a few weeks and then fly further south to Spain. Those that come here one year may go elsewhere another year. Their population in Europe is estimated to be thirty to forty million. Redwings are about the same size as song thrushes but are easily distinguished from them by the stripe over the eye and the rusty coloured flanks. It is generally not easy to get near them but during the severe frost last January they had to abandon the open fields and look for food in sheltered areas and gardens - hence the picture.
