David Attenborough presents the sounds and story of the Dartford warbler.
Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. David Attenborough presents the Dartford Warbler. Dartford Warblers prefer Mediterranean wine-producing climates, which means ice and snow is bad news for them. The harsh winters of 1961 and 1962 reduced the population to just 11 pairs, but fortunately the numbers have since recovered.
