Tweet of the Day is a series of fascinating stories about the British birds inspired by their calls and songs.

Michaela Strachan presents the white-tailed eagle. These magnificent birds, sometimes called the sea eagle, are our largest breeding bird of prey and in flight have been described as looking like a "flying barn-door". The adults have white tail feathers, a bulky yellow bill and long parallel-sided wings: they really do deserve that barn door description.
