摘要

The population collapse of resident Gyps vulture species in South Asia, caused by the use of a veterinary drug diclofenac, has highlighted an urgent need to monitor numbers of other vulture species in the region. This study assessed population trends of Himalayan Griffon Gyps himalayensis in the mountainous region of Upper Mustang, Nepal, which is an important breeding area for the species. Vultures were surveyed in 2002, 2004 and 2005 by recording the number of birds sighted along 188 km of transects, and observing numbers of birds at breeding colonies. The number of birds recorded per day and per kilometre of transect declined by 67% and 70% respectively over the period of study. The number of active nests declined by 84% from 2002 to 2005. The veterinary drug diclofenac was available in pharmacies in the Mustang region. Young Himalayan Griffons, which migrate to the lowland areas of Nepal and, in increasing numbers to India, are highly likely to be subject to diclofenac poisoning. If this rate of population decline occurs throughout the Himalayan region, the conservation status of the species will need to be urgently reassessed.

根据一个调查，在Upper Mustang地区繁殖的高山兀鹫，从2002年开始繁殖大量的减少，可能也是跟南亚平原的兀鹫一样，受diclofenac的毒害。

在青藏一带的鸟类学者，应该慎重注意青藏高原的兀鹫数目，不要亡羊再补牢。

原来有个帖子也说到止疼药对鸟类，兀鹫的影响，我有点不理解，人类用的止疼药总数量还是有限的，跟农药的量没法比，我小时候打农药（六六粉）的时候要关窗户，屋外象刮沙尘暴一样，

止疼药真的对兀鹫的繁殖造成影响了吗

不是所有的止痛药，据研究只有一种，而且是在南亚观察到的。至于中国是否会受影响，还需要进一步的了解研究。
