My next episode of BBC Radio 4’s Tweet of the Day was aired this morning, all about the corncrakes we discovered on the Treshnish Isles while looking for puffins. Corncrakes are absurdly rare, and I have never been more excited to hear the grating Crex crex call of this elusive bird. They are related to moorhens, coots and rails, and up until the end of the eighteenth century were widespread across the rough grasslands, pastures and meadows of Britain. Intensive farming has pushed them to the brink of extinction and they are now the focus of huge conservation efforts.
