Title: Diclofenac and Vulture Conservation 禿鷹數量激降
Post by Etta on Jul 24^th, 2004, 4:01pm

適值《香港鳥類攝影圖鑑》新出版，當中載有1999年訪港禿鷹的珍貴圖片。

剛巧日前，有篇報章的文章，記述殺蟲劑 DDT 令游隼的蛋殼變薄的肇因並報導印度的禿鷹間接因止痛藥 Diclofenac 而致數量激降。

文中報導本年初的印度禿鷹資料，實值得暸解和警惕啊！

Manifesto on Diclofenac and Vulture Conservation
"Three species of Gyps vultures (G. bengalensis, G. tenuirostris, G. indicus) have declined at an alarming rate across India, Pakistan and Nepal in the last decade."  "Recent scientific evidence indicates that diclofenac (a non-steroidal anti-inflammatory drug) is a major cause of the observed vulture declines."

Diclofenac – the mystery solved
"The observed rate of vulture population decline (30% per year) can be induced even if less than 1 in 200 of the carcasses available to vultures contain lethal amounts of diclofenac"
