That's a thrush-mix; playbacked at a ringing-track
I had missed a stage :CBluethroat for me.
The date is amazing.

..settled? ID please..
the thrush-mix is only very faint in the background. Only excellent hearing and very good ID skills should hear it.
But oh, you missed the Greenshank too.. nor Bluethroat in this recording.
Out of interest, why did you post the recording in the first place? You knew it was a mix on a loop at a ringing station?
