Dropping dead: causes and consequences of vulture population declines worldwide
Vultures are nature's most successful scavengers, and they provide an array of ecological, economic, and cultural services. As the only known obligate scavengers, vultures are uniquely adapted to a scavenging lifestyle. Vultures' unique adaptations include soaring flight, keen eyesight, and extremely low pH levels in their stomachs. Presently, 14 of 23 (61%) vulture species worldwide are threatened with extinction, and the most rapid declines have occurred in the vulture-rich regions of Asia and Africa. The reasons for the population declines are varied, but poisoning or human persecution, or both, feature in the list of nearly every declining species. Keyywords: scavenger, condor, ecosystem services, carcass, decomposition, disease transmission, vulture decline, poisoning, persecution, Africa, Asian vulture crisis, vulture conservation, diclofenac, furadan.
