Electric infrastructure poses a significant threat at congregation sites of the globally threatened Steppe Eagle Aquila nipalensis in Saudi Arabia
Published online by Cambridge University Press: 15 June 2021
Summary
Saudi Arabia is the fastest growing electricity consumer in the Middle East, with a rapidly expanding network of powerlines. Bird mortality through electrocution and collision has been recorded in the country, but so far there is little information as to how much the electricity infrastructure affects globally threatened raptor populations that migrate to Saudi Arabia. In 2019, the world’s largest wintering congregation of Steppe Eagles Aquila nipalensis was discovered near a rubbish dump in central Saudi Arabia. We evaluated whether powerlines in the vicinity of this, and another congregation site, caused mortality of large birds. In November 2019, we surveyed powerlines within 6 km of two focal rubbish dumps at Al Qunfudhah (12.4 km) and Ushaiqer (2 km). We found 52 carcasses of five species, of which 85% were Steppe Eagles. Based on the age of these carcasses, we coarsely extrapolate that 14.4 km of powerlines near these two congregation sites may kill 94–240 Steppe Eagles per winter, representing up to 0.3% of their global population. We call for the urgent safeguarding of powerlines that cause mortality near known Steppe Eagle congregation sites, and the adoption and implementation of regulations that ensure that future infrastructure is constructed with designs that are safe for birds.
