2012-Oct-04, 馬料水渡輪碼頭 (Ma Liu Shui Ferry Pier)
It has a broad white supercilium which is almost around the head.
This white supercilium and black eye stripe recall my memory of the previous record:
粗白的眉(幾乎繞頭一圈)和黑色眼條紋令我想起之前的記錄:

It was mobbed by a Collar Crow.
I felt that its length is about 80-90% of that of the Collared Crow.
(The right one is the Collar Crow)
牠正被一隻白頸鴉驅趕.
其長度大約是白頸鴉的80-90%.
(右邊的是白頸鴉)
And here is the video:
這裡有記錄片:

From the picture of Northern Goshawk found in the book, I can't see the white dots on the upperpart plumage.
牠的背部有很多白點,但圖鑑的圖片卻沒有.
Thanks for your help!
多謝指教!
