Hi again Delia,
I thought the bird you asked about looked like
this bird, which I find is actually a link to the Internet Bird Collection, not HBW copyright stuff. Note the lack of red in the wing panel (though there is a hint of one mostly hidden red secondary, which I mentioned earlier would seem to fit with kumaiensis. Also note the bill pattern which fits, too.
From HBW Alive: Small olive-grey babbler with forked tail, red bill, yellow throat, orange-yellow breast, and red to yellow wing markings....Race kwangtungensis is like nominate, but with yellower-tinged crown to nape, more olive-toned posterior upperparts, yellower face, neck side and underparts, orange patch at base of secondaries;
kumaiensis has greener crown with more restricted yellowish wash than nominate,
little or no chestnut-red wing patch but orange-red distal outer fringes of inner primaries, patch at base of secondaries orange;
calipyga is similar to previous but yellower above, orange-red fringes of inner primaries extending entire length of feathers;
yunnanensis is similar to kumaiensis above, but lores and ocular area whitish, chin to breast paler,
wing with no red or orange colouring.
I have no persosnal experience of these birds except for the local escapee population I mentioned, so this post exhausts my knowledge. I hope someone from or with knowledge of the bird's home range will comment.
