Wedge-tailed eagles have found a new but unlikely prey in the Western Australian goldfields: mining company surveying drones.
South African goldmining company Gold Fields, the world's seventh-biggest gold producer, has lost nine drones to the birds, costing the company more than $100,000.
Wedge-tailed eagles are one of the largest birds of prey in the world.
Their wingspan is more than twice that of the one metre-wide drones and they have razor-sharp talons that allow them to grab and destroy the drones in flight.
