Thanks Gandytron! I am almost sure that it's a male Black-throated Thrush (Turdus atrogularis), but almost...
Pavel, yes after I posted it occurred to me that B-t Thrush might well fit the bill and is far more likely that Japanese Thrush. I am interested by the apparent clean white underparts with apparent spotting on the breast sides. Is that consistent with black-throated ? (I have not seen a black-throated thrush for about 20 years so cannot really remember!).
Best wishes,
Dave
Why not a slightly blurred Song thrush?
The throat looks brown on my monitor.

Another for song thrush. I'd be interested to see what the Bulgarian Rarities Committee makes of it.
