Does anyone have IDing experience of the two (allo)species?
I cannot seem to find comparative text on the internet or in my sparse library. I have looked at a number of web photos (including Adey Baker's of the former species and Wigan's of the latter here in the Gallery).
For adult males at least, it seems to me:
Eurasian: Larger mask and unbordered, greyish-white crown/head, a good bit of brown under, and a rich chestnut mantle.
Chinese: Narrower mask bordered with narrow white which contrasts with the grey crown, little or no brown on the grey breast, mantle grey-brown or brown-grey or grey.
From what I've written above, Chinese seem similar to female Eurasians. And then there are the females and juveniles and winter birds, whose photos leave me confounded.
Any pointers or links you can give me? I would be grateful.
