Aberrant Bush Warbler的用法和样例：
- This is probably a Korean/Manchurian Bush Warbler due to rufous crown and bright upperparts. I meant the bird on the other thread was a Japanese.
- Japanese Bush Warbler at Chi Gu I found (in song) many years ago was greyish and greenish, those at Yeh Liu seem browner and darker grey (there are several races involved).
- There is a rose bush in front of the office.
- The bush was planted early on in the season.
