Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Kate Humble presents the red-throated diver. The eerie wails of a red-throated diver were supposed to foretell rain. In Shetland the red-throated diver is called the "rain goose" but anyone who knows the island knows that rain is never far away. Like all divers, red-throats are handsome birds with sharp bills, perfect for catching fish. In summer they have a rusty throat patch and zebra-stripes on the back of their neck but in winter they're mainly pearly grey and white.
