Thanks a lot for John's reply and accurately pointing out the distribution of and the difference between these 2 subspecies. Differentiation betweeen them has been difficult for me because these 2 subspecies have quite similar appearance and some White Wagtails (alboides) have a dark grey back.
White Wagtail race personata, India, Dec09
White Wagtails race alboides, Yunnan, Nov08
Congratulations to John A. on spotting this White Wagtail(personata) which is so rare in HK.
Thanks to Kwan and John H. for posting photos of this White Wagtail.
