Satellite-tracking BFS from Korea

Satellite-tracking BFS from Korea

Several young Black-faced Spoonbills were fitted with transmitter for satellite-tracking of their migration route in 2009 and 2010. Some details are shown in the this link:

Comparing to the previous satellite-tracking study which were made with catching birds from wintering grounds (in both Hong Kong and Taiwan), this is the first study to focus on the Black-faced Spoonbill's southward migration and only young birds could be caught and fitted with the transmitter. It also gives us interesting results. Two of the five young BFS moved to places where the other BFS would not usually go, one going into lower Yangtze River plain and another going to the southern coast of Vietnam (now! just yesterday). Both places have records of the BFS before but not regularly. This result also show that young BFS has a higher tendency to go away from the 'traditional' wintering grounds, perhaps they lack of experience of these traditional wintering grounds.

The bird going to Vietnam actually migrated through the East China coast in 7 days (from 4 to 10 November 2010), an interesting information of how fast they can do the migration. It flied close to HK in the southeast waters but not going to Mai Po. (Geoff: it is possible that one day you can see BFS from Po Toi!) It is also out of my expectation that the bird seems to migrate through the east coast of Hainan Island and then across the western part of South China Sea to southern Vietnam. I expect it would go along the south China coast to Red River Delta and then along the Vietnamese coast to the south. This bird may go further down to Thailand because there are regular winter records of young BFS in the Gulf of Thailand.

有趣的資料啊!謝謝分享!
但我有些問題想請教啊!


Year 2009
96704(K85)
2009-2010
96705(K86)
96706(K87)


>>> 在台南的網頁:PTT 96704應是K84, 96705應是K85, 而96706應是K86,跟日本網頁的編號不符,不知是日本那邊的資料錯了,還是台南的資料錯了,還是有其他原因呢?


Year 2010
42991(E**)
42994(E12) now tracking!


>>> 從台南網頁2010年應只有2隻BFS帶PTT,一隻是E09,一隻是E12,不知上述E**是否等於E09呢?


謝謝!

那個網站的資料是日本及韓國的研究人員聯合製造的, 也就是做這次追蹤的同一組研究人員, 我想他們的資料是正確的!!

E09来过浙江,听说很久没收到E09的信息了, E09的信号消失地是哪儿呢?
