Thank you very much. Maybe I misunderstand what is tertials.
Perhaps the following has been posted somewhere on this forum already, but via the Oriental Bird Club Yahoo! Group I came upon slides on identification of Phylloscopus and Seicercus warblers:
English:

Chinese:

Both can be downloaded at the bottom of Per Alström's site:

Pages 6 and 7 show a picture of a warbler and its topography. This will be helpful to you, I guess.
