尋找彩色環誌的鵐 Watch out for colour-ringed Buntings



由於黃胸鵐及田鵐的數量正在急速下降,為了深入了解牠們的遷徙路線和存活率,俄羅斯的鳥類研究員於2015年的繁殖季節環誌了7隻雄性的黃胸鵐及田鵐,其中3隻在2016年再次回到繁殖地。為了比較其他相似物種的存活率,鳥類研究員於2016年春夏季共環誌了約200隻鵐,種類更擴大至灰頭鵐、栗耳鵐、蘆鵐及紅頸葦鵐,牠們的環誌特徵是一隻腳有彩色環(上)及金屬環(下),另一隻腳有2個彩色環,而使用的彩環顏色有黑、藍、綠、橙、紫、紅、白及黃色。

隨著遷徙季節的展開,請各位鳥友及鳥攝者特別注意,若踫到腳上有彩色環的鵐科雀鳥,請記下品種及兩隻腳上環的顏色,若有照片記錄更佳,然後將有關資料電郵至yvicky@hkbws.org.hk

誠邀大家為鵐類雀鳥保育出一分力!!謝謝!!

Rapid declining population trends have recently been found for Yellow-breasted Bunting and Rustic Bunting, but knowledge about their migration routes and survival rates is still very limited. During breeding season in 2015, a colour-ring study was started in Far East Russia with seven male Yellow-breasted Buntings and Rustic Buntings ringed. Three out of seven individuals safely returned to their breeding grounds in 2016. To compare survival rates among sympatric breeding species, Black-faced Bunting, Chestnut-eared Bunting, Common Reed Bunting and Japanese Reed Bunting were included in the study. During spring and summer 2016, almost 200 buntings were equipped colourful ring combinations. All birds ringed in this study have one colour-ring above the metal ring on one leg, and two colour-rings on the other leg. Used colours are black, blue, green, orange, purple, red, white and yellow.

Autumn migration has begun, may bird watchers and photographers please report to us if you have encountered any ringed buntings. Please provide in the email the bird species as well as the colours of the rings on both legs (it would be good to have photos) and send to yvicky@hkbws.org.hk
