Urban Dawn Chorus
Tweet of the Day is a series of fascinating stories about British birds inspired by their calls and songs.
David Attenborough introduces the final recording marking International Dawn Chorus day. The urban dawn chorus was recorded by Chris Watson in Whitechapel, London as part of a project to enable the children of the Royal London Children's Hospital to hear the wildlife sounds on their doorstep. Birds featured include the robin, blackbird, great tit and house sparrow.
