Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. David Attenborough presents the Swift. Swifts live in the sky, feeding, mating and sleeping on the wing. Their feet are so reduced they cannot stand particularly well on land, only the near vertical surfaces on which they build their nest.
