Wow, what a fantastic series of photos. Lucky you for observing something like this!

The snake looks like a Checkered Keelback, which is common in this part of Hong Kong.

This bird is still in its first year, but already skillful to catch a snake.  I bet it will survive to become an adult.

I had actually been puzzling over the age of this bird, and would be interested to know which features you used to age it Ho-fai.

The bird has clearly moulted out of juvenile plumage (which is largely white) into an adult-like body plumage. I would not have expected a bird in it's first calendar year to have completed body moult by October (compare this bird in December: http://orientalbirdimages.org/se ... _ID=&pagesize=1).
However, the wings and tail are not those of an adult, with more narrow bars rather than the broad black and white bars associated with adults. I cannot make out any moult contrast in the wing or tail to suggest the bird is moulting into adult plumage, and the feathers appear to all be the same age.
The best conclusion I had reached was that this was a second calendar-year individual, which had moulted into adult plumage but still retains juvenile wing/tail feathers. I'm not sure if this is correct though, and I would expect at least some moult - which is why I'm confused!

不好意思，請問這隻大冠鷲跟下面這個連結是同一隻鳥嗎？

大冠鷲這麼不怕人是很難得的，但如果是用餵食的方式去得到照片，對鳥的本身野性是否會有影響？

Should think it is the same eagle resting in Yin Kong.  I went there yesterday morning.  I understood from the photogers that there had been no feeding from the photogers.

Hi,blackpipi

應是同一地點,但不同日期拍攝,本人所拍的照片當日早上只有我和四位友人拍攝,拍了個多小時便走了,至於它吃的蛇是它自然捕捉回來不是餵食的,
我也以為自己很好運氣拍到蛇鵰捕食蛇的過程,但期後從友人得知,他曾看見此鵰一個早上捕獲過六條蛇,以我觀察所得這鵰捕獲獵物後會就地進食,完全不理會旁邊的人,我也很迷惑為甚麼這鵰會這麼不怕人.此蛇鵰這麼容易拍攝,有身份証都有的情形底下,這難得機會自然會吸引很多人去,這在所難免,只要大家自律,問題都不是太大.

話說回來,為甚往往有些人看了一些難以想像怎樣拍攝的相片後,就只會聯想是餵食或是captive,跟住就道聽途說,上綱上線,為甚不是正面地想拍攝者用了多少時間等候, 耐性, 運氣等…..真奇怪

Seeing the pictures of people standing on the fields to photograph this bird, I understand why the HKBWS has reissued their request to respect farmers rights in Long Valley:
http://www.hkbws.org.hk/BBS/view ... 9293&highlight=

Please do not walk on farmers fields, to avoid causing any damage to crops or land.

jojomau

I concur with ajohn.

Yesterday, when the eagle drank from a spring, many photgers simply rushed to good spots on farmland.  I should think we would have to bear the consequence as a whole later.  Could we convey the message to some of the key figures of the photogers?  I understand that some of them have frequented their visits there for a number of days.  I have asked my friend who know some of them to spread the words.

Actually, the spot is now a multi-region attraction.  I met some from mainland yesterday.  From the URL cited above, the photogers might have come from Macau.  Could we try harder to keep LV a place with welcoming arms for bird lovers?

John, I think you are right. I see from the tail that is is an immature, but I am not sure about the timing of the post-juvenile moult.

Dear birdwatchers,

Please make every effort not to damage crops.  If there is any damage, I think the farmer should be compensated, and of course an apology is in order.

Hi,HF Cheung

有台灣的網友告知我這應是第一年的幼鳥.他說在台灣蛇鵰幼鳥的色型有兩種，一種是淡色型，一種是類似我拍的暗色型(有成鳥的體羽) 。
如果香港的亞種和台灣一樣,從我拍攝的照片所見,可從尾羽及飛羽的特徵與完整性來判斷，是隻今年生的暗色型幼鳥。
一般在台灣的觀察，幼鳥是第二曆年的春天左右會開始換羽 .
