Flock of Whoopers heard at 20:10 but we were unable to see them so no idea on numbers but they were very vocal and sounded ! to be heading >W or NW maybe towards Ogden or Fly Flats direction. I guess if the night is clear with a quarter moon then they will probably keep going unless they  hit some fog and come down at Ogden, Mixenden or Fly (?) - if anyone is passing to check any of those sites in the morning ?
