Springtime is a wonderful time to hear birds singing, obviously a Nightingale takes some beating but a Song Thrush or Blackbird certainly comes to close but to me one song stands out like no other and I have only heard this sound once and that was 3 years ago at Lakenheath Fen RSPB. There are only a handful of places where these birds can be found in Britain and we have one of these sites and it is of the Golden Oriole, I haven't seen one but that fluted song is ne'er to be forgotten
