One swallow doesn't make a summer but it comes close: Brett Westwood explores a much loved and inspirational bird whose own definition of happiness is a field of cow dung. Mark Cocker is in one such field in Derbyshire; Anders Pape Moller catches breeding swallows in a cow byre in Jutland; Angela Turner tells stories of how we've adored and exploited swallows, Anthony Roberts and Ellie Ness lead a swallow ringing on the Isle of Wight and we hear from Katrina Bradley as she watches swallows in the Nigerian village of Ibaken.
