Bill Oddie presents the chiffchaff.
Tweet of the Day is a series of fascinating stories about the British birds inspired by their calls and songs.
Bill Oddie presents the chiffchaff. Chiffchaff are small olive warblers which sing their name as they flit around hunting for insects in woods, marshes and scrubby places. Chiffchaffs are increasing in the UK and the secret of their success is their ability to weather our winters. Many stay in the milder south and south-west of England where the insects are more active.
