In this episode we take the opportunity to meet the warblers, millions of whom travel thousands of miles every year, returning to the UK to breed, and sing - possibly in a tree near you! We then reveal the often overlooked acoustic charm of the long tailed tit. [Timings: Willow Warbler @ 2mins 19secs; Blackcap @ 13mins 45secs; Long tailed Tit @ 25mins 03secs]
