The Egyptian vulture was once considered to be fairly common and widespread throughout most of its range in Europe, Asia, and the dry parts of Africa north of the equator. Unfortunately, this is no longer the case. Populations have plummeted due to a host of threats; chiefly, secondary poisoning (of their prey), problems posed by energy infrastructure, decline in food availability, and human disturbance.
Poisoning. Egyptian vultures also fall victim to poison and pesticide applications used to control four-legged predators and rodents, wreaking havoc on their population. A rising issue is the widespread use of diclofenac in veterinary medicine - this medication is fatally toxic to vultures scavenging on livestock carcasses treated before death with this medication.
Energy infrastructure. Second among threats to Egyptian vultures is energy infrastructure. Collisions with electric power lines and wind turbine blades are often fatal for Egyptian vultures and other larger birds; the same is true for electrocution and feet entanglement in overhead cable twists or clamps. The current conservation focus in Kazakhstan seeks to address the threats posed by transmission lines nationwide and poorly-regulated siting and development of wind farms along the Western Circum-Himalayan Migration Corridor (WCMHC), a major pathway for the Egyptian vulture and other birds of prey.
Decline in food availability. Third among threats to Egyptian vultures is the decline in food availability, traditionally associated with declines in the number of wild ungulates, tightening sanitary standards for the disposal of dead livestock, and changes in landfill management.
Human disturbance also threatens the Egyptian vulture’s survival. Ornithologists have documented huge nest losses attributable to human disturbance; notably, the location of Egyptian vulture nests closer and closer to farms and places where humans are present. In Kazakhstan, most of the country’s mining operations occur in the south and southeast, including in the Karatau Mountains, all key locations for Egyptian vulture populations.
