Redwing

Redwing

Turdus iliacus
Redwing, Liz Cutting

Introduction

One of the 'winter thrushes', the Song Thrush-like Redwings begin arriving in Britain & Ireland during the latter half of September, before leaving again by mid April.

It is estimated that around 700,000 Redwings winter in the UK, although numbers can fluctuate sharply between years. Redwings come in search of berries, and, when crops fail in northern and eastern Europe, large numbers cross the North Sea. A small number of Redwings also breed in the UK, but only in the far north of Scotland.

During the early winter the Redwing is very much a bird of open country but during freezing conditions Redwings can often be seen in parks and gardens. With birds arriving from both Iceland and Fennoscandia, Redwings can be found across Britain & Ireland during the winter months.
