Thank you 輝哥!
請問主要係留意翼(肩)的白點?
定頭後淺色d? Author: HFCheung Time: 24/02/2011 10:19
Yes, either can be used in HK.
The colour of the nape is the best, most easily seen from a distance. No other Eagle in HK show this colour on the nape.
The white on the shoulder is a deeper confirmation. By the time you see the white spots on the shoulder, the colour on the nape should be very obvious.
