What an odd plumage. But appart a Yellow-browed Warbler I don't see what else it could be.

how about the colour in leg in black???

Yes why not a Hume's Warbler, the dark legs are good for this species,but the plumage I guess is not enough washed out. I think that without its call it will be hard to ID it certainly. I let other people with better experienced of the species give their opinion. But I'm not sure both species can be separate in the field without hearing the call. I think that even on hand it's impossible, but since this bird is in very fresh plumage maybe not.

Not a typical Hume's which would not show such green finges to the flight feathers and tail and the blackish centres to the greater coverts. However, inornatus nevers shows such cold plumage tones to the head (and lacking any yellow in the super) and mantle at this time of year and the black legs, feet and claws and to a lesser extent the large area of dark on the lower mandible is never shown by inornatus and is classic Hume's.

For me, a slightly odd Hume's Leaf Warbler. It is also worth nothing that much of what is known about the id of Hume's relates to nominate humei, and there is much to learn about the id of mandelli, which this bird could well be/probably is... I recall seeing mandelli many years ago in Yunnan in winter and being struck by how green the fringes to the primaries were.

Isn't the extensive black shadowing of the wing bars on the base of the secondaries a feature which favours Yellow-browed over Hume's? Although I agree that the colours do not fit a typical Yellow-browed.
