There might also be waders with colour rings like this Great Knot from Australia last year:
http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4
in which the colour and position of the plastic colour rings and leg-flag enable identification of individual bird.
Please record the colour and sequence of rings/flag on each leg. For example, the bird in the above link is:
Upper Left: nothing
Lower Left: yellow FLAG - red - lime
Upper Right: nothing
Lower Right: blue - blue
The easier thing to do might be taking a record shot.
Don't forget to record the SPECIES! Additional information on % breeding plumage will be useful as well.
Please keep an eye on them.
Thanks,
Katherine
此外, 鳥友亦可能發現繫有多個顏色腳環的涉禽, 如去年春季曾發現的一隻來自澳洲的大濱鷸:
http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4
每隻涉禽個體的腳環及腳旗的顏色與位置不同, 因而可辨認每個個體.
請詳細記錄每隻腳上的腳環及腳旗顏色與位置, 例如以上連結中的大濱鷸是:
左上: 沒有
左下: 黃腳旗 - 紅 - 淺綠
右上: 沒有
右下: 藍 - 藍
拍一張紀錄照可能是比較簡便的方法.
請不要忘記記錄該鳥的品種! 另外, 繁殖羽毛的百分比亦是很有用的資訊.
請幫忙留意, 謝謝!
Katherine
