Being a human, being a bird, is fun, stupid, impossible, tragic, sweaty, lonely, wild, restless and death to your vocal cords. So says theatre maker Tom Bailey who has spent much of 2018 following in the migratory restlessness of the marsh warbler in his Tweet of the Day. Tom has chosen his five episodes from the Tweet of the Day archive which you can hear all this week. In addition you can hear more from Tom and his artistic work Zugunruhe, an ornithology term for 'migratory restlessness in birds', in the Tweet of the Week podcast, available on the Radio 4 website as a download.
