A Castlemartin Corn Bunting??

The following interesting email arrived today from Prof. Gareth Jones, Bristol. Gareth is a regular visitor to Pembs with students studying bats:

"Hi Bob
On the Orielton field centre Bat course I thought I heard a corn bunting singing at
Castlemartin on Fri 11th. Back at the field centre I was surprised to read
that these were now extinct as a breeding species in Wales. I tried to go
back on 13th, but there was an unscheduled evening firing and I couldn't
get across the range. The bird was audible from the Green Bridge, and
seemed to be singing inland to the NW of the bridge. I may have
misidentified, but I've heard quite a lot of corn buntings before and they
are quite distinctive. A second opinion would be valuable!"

So, if anyone is in south Pembs in the Castlemartin Range vicinity - please carefully listen out and look - especially along the Stack rocks/Green bridge of Wales road - it would be nice to confirm this species with its very distinctive song!
