（2025届河北省高考三下学期高考冲刺模拟考试（Ⅱ）英语试题）Scientists in Australia have used Artificial Intelligence (AI) to help them locate a rare bird called the Plains-wanderer. This new information will help scientists protect the birds, which are endangered.
The Plains-wanderer is a small bird that lives in Australia’s grasslands. Not just any grasslands. Plains-wanderers are picky. There can’t be too much grass or too little. Zoos Victoria, the group behind the recent effort to locate Plains-wanderers, says the birds’ number has fallen by over 85% in recent decades as grasslands have been turned into farms and cities. Scientists believe there are now only 250 to 1,000 of the birds left in the wild. Scientists have put the species into a “family” all by itself, since there are no other similar birds. The female Plains-wanderers are larger, and are in charge of protecting the territory while the male birds are smaller and take care of the eggs.
To protect these rare birds, scientists first had to learn where they were, so Zoos Victoria worked with Queensland University of Technology on a plan to locate the birds. Since Plains-wanderers were hard to spot, the team chose to “listen” for the birds instead. Female Plains-wanderers make an unusual “Ooom” call, and this is the key to locate them.
The researchers set up 35 special recording devices called “song meters” in nine different grassy areas where Plains-wanderers could possibly have been. Song meters recorded all the sounds made in an area over a long period of time. The song meters collected tens of thousands of hours of recordings——far more than humans could analyze. So the researchers fed the recordings to an AI system trained to identify the calls of Plains-wanderers. The AI system discovered Plains-wanderer calls coming from two of the sites. The scientists double-checked and found that the AI system was correct. Chris Hartnett, who worked with Zoos Victoria, said it was like “finding gold”.
The new information will help scientists protect the birds. And the researchers are still “listening”— using song meters and AI to try to locate more of these Goldilocks birds.
