Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. Steve Backshall presents the tree pipit.

Tree pipits are small brown birds without any bright colours or distinctive features; but you can identify one from a distance when it is singing, because it has a very obvious display flight. The male bird sings from April to the end of July, launching himself from a treetop perch, then parachutes downwards like a paper dart.
