Actor and keen birdwatcher Samuel West returns to Tweet of the Day for this his second week, rummaging through some of his favourite episodes from the back catalogue. In this episode Samuel recalls an early morning family visit to Oare Marshes in Kent where hearing nightingales and turtle dove reminded them of the decline in these species since the 1970's. You can hear Samuel's selection from greenfinch to turtle dove all this week on Radio 4, from Monday through to Friday at 05.58. And you can hear more from Samuel in the Tweet of the Week omnibus podcast, which can be found on the Radio 4 website, or can be found on the BBC iplayer Radio App by searching search for Tweet of the Week. Producer : Maggie Ayre.
