Tweet of the Day

Actress Kirsty Oswald has embarked on an ambitious bird-watching feat; over the course of a year, she plans to spot 100 different species of bird in the British Isles. In this episode of Tweet of the Day, she explains how a serendipitous walk led to her undertaking such a task, and how enthusiasm, enjoyment and a love of walking can be more fortuitous than formal ornithological knowledge.

For Rachel Unthank a lifetime interest in the magpie provides inspiration for this Tweet of the Day. Along with her sister Becky, Rachel is part of the family affair The Unthanks from the North East of England. As one of the leading exponents of traditional music The Unthanks are equally at home playing to Tyneside folk club one night, 2000 Londoners the next before inspiring the next generation of songwriters at a primary school. They see their work as delivering an oral history for the modern audience. Which is perfect for Tweet of the Day, as Rachel recalls how her son drew her a special button to represent a magpie, and why offering an old lady a lift may inspire some deep held beliefs on the role of magpies in bringing bad luck as they cross your path..

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.

For writer, gardener and TV presenter Monty Don, swallows are as central to his garden as any plant. Their return to the garden in April brings a soaring familiarity of song, which when they depart in September leaves the skies above silent and empty, and for Monty a feeling of loss and longing for their return after the long winter months. Monty Don takes over the Tweet of the Day output this week with a selection of seasonally relevant episodes by Sir David Attenborough. Producer Andrew Dawes

For writer, gardener and TV presenter Monty Don, the changing seasons herald different sounds and atmospheres in the garden. In autumn as the leaves begin to fall, the arrival of flocks of fieldfares from the north of Europe are as much a part of the garden in winter as are summer migrants during the long days of June. A mixture of truculence and shyness, everything about fieldfares is harsh or jerky, but for Monty he likes them.
