Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.

David Attenborough presents the story of the Black-Necked Grebe. In winter, the black-necked grebe is largely grey and white with a dark cap and eyes like rubies. You'll need to seek out Black-necked grebes in their favourite spots, which include large London reservoirs and shallow seas along the south coast.
