Spectacles and long tail make me think it's not a sparrow, but I've been wrong before, many times.
Is it an Ortalan Bunting? Her's another image.
This is a stunning male Ortolan Bunting :-)
And to help further, using the Merlin Bird ID app on my iPhone, it identified the image as Ortolan :-)
Thanks once again Tommy. Will try Merlin, thanks.
First time I tried it myself :-)
