For Becky Unthank her interest in birds goes beyond just watching them while out in the countryside, as she has recently named her son wren to reflect her love of the natural world. Along with her sister Rachel who will present her own Tweet of the Day next week, The Unthanks is a family affair from the North East of England. As one of the leading exponents of traditional music they have been nominated for the Mercury Music Prize and represent the only British folk group in the The Guardian's and Uncut's best albums of last decade. Categorizing their music is difficult, but The Unthanks see their work and songs as less a style of music and more delivering an oral history for the modern audience. Which is perfect for Tweet of the Day, as Becky Unthank recalls how her son was named wren and also how she has been inspired by the story of the King of the Birds. You can hear more from Becky in her Tweet of the Week podcast, downloadable from BBC Sounds Producer Andrew Dawes
