But what do the birds make of this invasion of their territory With strict animal ethics approval, we flew drones towards flocks of birds in Queensland’s Moreton Bay. We found many species were not disturbed, provided the drone was small and flew above 60 m. The exception was the critically endangered eastern curlews (杓鹬), which became alarmed and flew away — even when a tiny drone approached at the maximum legal altitude of 120 m. But when eastern curlews took flight, other nearby species were often startled, creating a domino effect that eventually caused the whole flock to take flight. Drone disturbance can interrupt birds as they rest or feed. It can even cause them to avoid some locations altogether.If the birds are consistently interrupted or scared away from their preferred habitats, they may find it difficult to eat and rest enough to survive and reproduce.This is particularly concerning for species such as eastern curlews, which migrate thousands of kilometres to breed. We studied a diverse group of birds typically found along coastlines, known as shorebirds. Heartbreakingly, their global population has plummeted as they continue to battle habitat destruction, sea level rise, disturbance and hunting. The last few decades have been bleak for the eastern curlew, which is the world’s largest migratory shorebird. Research in 2011 indicated a population decline of 80% over three generations. While drones are unlikely to have played a major role in shorebird decline so far, our results, combined with the increasing presence of drones along our coastline, indicate they could become yet another source of disturbance for these birds, many of which are already endangered. Drones can be beneficial in many ways, but we must identify when and how drones can be used to minimise potential harm. In some locations, such as some Australian national parks, drone use is already prohibited or restricted.But managers need to understand how drones affect wildlife to inform these regulations. 1．What’s the problem with eastern curlews A．They are being killed.
