Here is a Yellow Wagtail in Dongyin island, Lienchiang County, Taiwan. Could anyone help to ID between M.t.macronyx/M.f.thunbergi, plz? Are there any stable characteristics to tell the difference?
(IMO, macronyx is more possible than thunbergi because of the clean front area, obvious yellow wingbars, and not so dirty breast-side patch.)
