The trees outside our apartment in Ilfracombe attracted lots of little Willow Warblers, feeding on the aphids! I'd never seen so many of these pretty birds before, or got any photos!!
They are summer visiters to the UK and almost identical to Chiffchaffs.... the only ways to tell them apart is the colour of their legs and their differing songs..... Willow Warblers have light coloured legs and Chiffchaffs are dark. :)
