S21在香港2014
« 於: 五月 18, 2014, 10:26:42 pm »
有些黑面仔愛四處趴趴走,
有些則像這隻S21一樣,
整個冬天都待在香港,
頂多偶爾到附近走走罷了,
甚至在其他鳥兒們都早已北返的現在,
牠還賴著不肯走

今天(2014/5/29)收到Dr. Lee的消息
S21終於在26日早上趟上北返的旅程了
27日到達了福建福州

另外
A26於5月10日發現在Sokdo島上養育2隻雛鳥
A26是香港於2002年救傷的鳥
推估現在至少已16歲, 可能是現在野外繁殖的繫放個體中年紀最大的了

Dr. Lee今年已發現了17個繁殖島
估計約有700對繁殖鳥

Dear Yat-tung, and all,

How are you?
I am sending you the migration news about  S21 banded from Yeonpyungdo at 2013 year.
S21 has moved to Fuzhou at 27th May. It has started to migrate in early morning of 26th May from Maipo, Hong Kong.
It has passed by Quangzhou at 23:00 and arrived on the coast of Putian. and It again flew to Fuzhou and staying on there.
It is the place tht S21 stayed for 5 days during the southern migration in last Oct.   
S21 has spent all winter in Hong Kong from 5th Nov. 2013 until 25th May. 2014. Maipo reserve was the main roosting site. . 
It used to go to Wetland Park and Nam Sang Wei until April. seldom to Inner Deep bay and  Shenzhen.
But it has changed the main feeding sites to the tidal zone of Inner Deep bay at May.
It is so interesting! I hope it can migrate along the coast of China in safe and going back again to HK.

By the way, I found A26 which was rescued and banded from Hong Kong caused by Botulism at Jan. 2002.
The color bands just remained yellow and blue. I could identify it was A26 by wrinkle shape of the upper bill. A26 was raising 2 chicks at 10th May on the breeding island, Sokdo, Incheon. I think the chicks are now almost leaving the nest. The age of A26 could be at least 16 years old, and it would be the oldest breeding one in wild by banding records.
I hope it can come again to breed in next year.

Now I am so busy to check the breeding sites of BFSpoonbills in Korea. I could find 17 breeding islands until now. The breeding population was summed on the highest records in this year, over 700 pairs. It should be hard works to check all islands by myself without any supports. I was exhausted and even no money to rent the boat for survey. Fortunately, I expect to conduct the banding project supported by National monument Center from 3-4 islands. I am going to band the chicks at June. I wish your encouraging words. 

Best wishes,

Kisup Lee

Dr.Lee有提及這一隻的腳環是黃-藍,確實是A26無誤,且如紅鳩所言,是指繁殖的個體。
A08仍是存在,是目前野外觀察到可以確認年齡中最高齡的個體!

Dr. Lee說的是
有"觀察"到確定在野外"繁殖"的繫放個體中, A26是最老的

A08沒有被親眼見到繁殖行為, 所以不在此列, 但牠是野外推估年齡最老的繫放個體

其中有個盲點是,
A08和A26雖然繫放日期相隔4年, 但繫放時兩者都已是成鳥
換句話說, 他們的繫放年齡從3到10餘歲都有可能
真實年齡誰大誰小, 沒人知道
現在的推估年齡都是用最小值來算的, 也就是至少XX歲

S21去年冬天(2013-2014)在香港度冬,
今年(2014)夏天在上海度夏的S21,
今年覺得頂山比較優,
跑來陪學會過冬囉
