My understanding and experience is that White-throated always shows a well defined pure white throat which is rather broad at the base. I think the 'pale' throated bird is clearly Silver-backed.

I certainly do not think the Birds of Korea photos are evidence for the pale throated bird being White-throated as a) they are not especially sharp photos and b) the bird looks more like Silver-backed to me especially given the apparent lack of pale lores...

Brendan,

Can you post a link to the Birds of Korea website for the photos you posted above as I cannot find them. Cheers.
