Following the instruction at http://www.nntp.hk[..]ldlife&xref=49971&server=news.hkpcug.org I able to find the place that a lot of eagle living. At first I don't know if it good to post it as may be this will attract a lot of people go there to take photos and affect their live. However this may not be a big due as local government plan to build a ferry port there. Please let me know if I should not post it.
Other than eagles, there are a lot of many other kind of birds live there, a very nice and convenience place for bird photo taking
