Is it a very late Arctic Warbler?
這是不是一隻遲來的極化柳鶯?

Thanks for help.

Two-barred Greenish for me.

Whilst the lower mandible appears to be distally dark, this is not clear and may be an artifact of the photos.  However, the width of the greater covert and median covert wing bars preclude the Arctic Warbler complex and are typical of Two-barred.  Structure (especially the rather short primary projection) and the dark-looking legs are also good for Two-barred.

Thank you Paul.
