Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
David Attenborough presents the starling. Throughout autumn parties of starlings have been crossing the North Sea to join our resident birds and as winter's grip tightens they create one of Nature's best spectacles. These huge gatherings, sometimes a million or more strong, are called murmurations and they offer the birds safety in numbers.
