Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Chris Packham presents the long-tailed duck. The musical call of the long-tailed duck gives it the Scottish name of 'calloo', or 'coal- and-candlelight'. In the UK you're more likely to see them in Scotland and northern England where they seek out shellfish, diving up to 60 metres to retrieve them.
