Do you have any more pictures of this bird, with the wing closed or upperparts showing? It looks very pale grey above, with black centres to the coverts. It may be a candidate for baicalensis.

Lovely picture by the way.

Hmmm. An interesting bird. The head pattern and small black breast patch possibly favour leucopsis. But the paleness of the back and lesser coverts, and the dark centres to median and greater coverts favour baicalensis. It's difficult to judge the extent of black in the rump/lower back which may help decide on ID.

I suggest you submit the photos to the Records Committee on an Unusual Record Form (http://www.hkbws.org.hk/web/chi/ ... ies_report_form.doc).
