Golden-breasted bunting?

Dust bathing.
I am not sure of the identification of this bird. There are several similar species, including the brown-rumped bunting and Cabanis's bunting, and there are a number of subspecies too. It is not listed on the latest Newquay inventory (for 31/12/15) or on Zootierliste. Suggestions are welcome.

Thanks to LaughingDove's suggestion, I now think this bird is probably a Somali bunting.
