Many Thanks~

按照上週六的室內講座的教導 (由雷進宇先生講解的"鶯的辨認"), Dusky Warbler 的眉紋是眼前比眼後白, 而Radde's Warbler 是相反. 另外Radde's Warbler 的上體的褐色是帶點橄欖綠的. 根據這些資料...我覺得是Dusky Warbler.

請其他高手指教...

Thanks in advise~~

我覺得都係褐柳鶯, 個嘴唔夠短厚. 當然要其他更有經驗的指辨.

仲想請問問你聽不聽到到''滴滴''的叫聲?

如有就更可confirm 了

Excellent.  Thanks for paying attention to the talk.  I think this is Dusky.  The bill is simply too thin for Radde's.
