Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Kate Humble presents the curlew. The haunting song of the curlew instantly summons the spirit of wild places.

Wherever they breed you'll hear the male birds singing and displaying. It's often called the bubbling song.
