Drones better at monitoring wildlife than humans: Study

New Delhi : Wildlife can be better watched with the help of drones which can detect small changes crucial in helping to save threatened species, said an Australian researcher.

The researcher employed thousands of rubber ducks to support his claims and kept them under drone observation, Xinhua news agency reported.

Experienced wildlife spotters were deployed in the area against drones to count birds.

Ground spotters counted the birds using binoculars or telescopes while a drone was flown over the beach, taking pictures from different heights and angles.

"We found it is more accurate and more precise to have people count birds from the drone imagery than to do it on location," lead author Jarrod Hodgson said.

As per results, the birds counted via drones produced better results than the ones who roamed in the jungle for the same.

Hodgson and his team developed a computer algorithm capable of counting birds from the drone images, yielding results on par with humans counting from the images.

"With so many animals across the world facing extinction, our need for accurate wildlife data has never been greater," Hodgson said.

"Accurate monitoring can detect small changes in animal numbers. That is important because if we had to wait for a big shift in those numbers to notice the decline, it might be too late to conserve a threatened species.

"For a few years now, drones have been used to monitor different animals that can be seen from above, including elephants, seals and nesting birds.

"But, until now, the accuracy of using drones to count wildlife was unclear," Hodgson said.

"We needed to test the technology where we knew the correct answer. We couldn't use wild animals because we could never be sure of the real number of individuals present."
