What bird is this?

I think they mean the melodic song - which is a Blackbird.

It also sounds like a human whistling - but Blackbird's can mimic human whistling.

The bird roughly playing the notes CDCAB slight pause FD. I don't know if that will help. The notes are in pitch order, A is the lowest note and F is the highest note.. It would be nice to upload the sound clip I made of me playing it.

It sounds very much like a Blackbird to me,I tried the notes on the guitar and even Mrs S agrees with that

Of course Dave it's what Mrs S fell for in the local folk club nearly 50 years ago
We have a couple of human sounding Blackbirds here at home, one seems to start with something like "scooby doo" and the other starts like "hurdy gurdy" I'm presuming these sre the same two birds we have had present for a while
