Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Bill Oddie presents the blackbird. Blackbirds are thrushes and the brown female often has a few speckles on her throat to prove it. Velvety, black and shiny, the males sport an eye-ring as yellow as a spring daffodil and a bill glowing like a buttercup. Happily blackbirds aren't doing too badly. There's so many of them that their territories often overlap so that where one song leaves off, another song begins.
