Thanks for this Grahame. I'm slightly confused, though, as the link you posted was for a blog post about a female Fujian. Was that for comparative purposes? I can see the difference in breast pattern, but that particular bird is also quite rufous brown on the flight feathers and tail. However, there's a bit of an olive tone to the nape, back and rump of the OP bird which is not evident in the duller brown Fujian on Steve's blog but can also be seen here:

Steve's bird is also cold whitish on the belly and undertail-coverts, whereas the OP bird shows more than a suggestion of tawny coloration in the same area.
Kunming seems to sit squarely in the middle of the south of the province. HBW states that
sundara occurs in the west and
denotata in the east, so I'm not sure which race this would be.
