Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
John Aitchison tells the story of the chough. Our healthiest chough populations are in Ireland, southwest and north Wales and western Scotland. The last English stronghold was in Cornwall and Choughs feature on the Cornish coat of arms. Even here they became extinct until wild birds from Ireland re-colonised the county in 2001. Now the birds breed regularly on the Lizard peninsula.
