摘要
本文报告了自 20 世纪 90 年代初以来在印度北部、中部、西部和东北部对秃鹫进行的一系列公路横断面调查中的第八次调查的结果。从 20 世纪 90 年代中期开始,白腰秃鹫 Gyps bengalensis、印度秃鹫 G. indicus 和细嘴秃鹫 G. tenuirostris 的数量迅速下降。减少的主要原因是兽医在牛身上广泛使用非甾体抗炎药(NSAID)双氯芬酸导致中毒。目前的调查结果表明,虽然所有三种秃鹫的数量仍处于较低水平,没有恢复的迹象,但自 2000 年代中期兽医禁止使用双氯芬酸以来,它们的数量似乎大致保持稳定。在印度,非法使用双氯芬酸和合法使用其他有毒非甾体抗炎药的现象仍在继续,而在尼泊尔,兽医使用有毒非甾体抗炎药的现象似乎已减少到较低水平,相比之下,印度的种群趋势更为积极。
Recent trends in populations of Critically Endangered Gyps vultures in India
This paper reports results from the eighth of a series of road transect surveys of Gyps vultures conducted across northern, central, western, and north-eastern India since the early 1990s. Populations of the White-rumped Vulture Gyps bengalensis, Indian Vulture G. indicus, and Slender-billed Vulture G. tenuirostris declined rapidly, beginning in the mid-1990s. The principal cause of the declines was poisoning due to widespread veterinary use of the non-steroidal anti-inflammatory drug (NSAID) diclofenac on cattle. The results of the current survey suggest that, while populations of all three species of vulture remain at a low level with no signs of recovery, they appear to have been approximately stable since veterinary use of diclofenac was banned in the mid-2000s. Population trends in India, where the illegal use of diclofenac and legal use of other toxic NSAIDs continues, are compared with more positive trends in Nepal, where the veterinary use of toxic NSAIDs appears to have been reduced to a low level.
