Scientists have used weather radar to map bird migration across Australia’s east coast for the first time, showing structured patterns that could shape conservation strategies. Using radar data from 2018-2022, researchers identified two main migration pulses: northwards from January to June, and southwards from July to December. Each autumn, an estimated 60,000 birds migrate per kilometer. The study, published in Current Biology, highlights the need for joined-up conservation, particularly as wind farms increase along migration routes.
Unlike Northern Hemisphere birds, many Australian birds migrate during the day, which may be unique. This research can support endangered species like the orange-bellied parrot and swift parrot by informing conservation planning. Next steps include combining radar data with citizen-reported sightings to pinpoint specific species’ movements. Researchers hope this approach will lead to targeted protections for vulnerable birds, especially in regions like the Great Dividing Range and Bass Strait where migration is prominent.
