Migratory shore birds gather in their many thousands on mudflats, sand bars and river banks. Somehow, they are able to live cooperatively and peacefully in close proximity to birds of their own and many other species. This has many advantages for individual birds. Field Ornithologist Ricki Coughlan reveals more of the amazing lives of migratory shore birds.
Chris Hassell, from the Global Flyway Network, looks at new research into the migratory shorebirds that inhabit Roebuck Bay at this time of the year.The satellite transmitter work uses newly developed, light weight solar-powered backpack harnesses suitable for both the larger birds (such as the Bar-tailed godwit), and now, for a medium sized bird, the Great knot. The Great knots are fitted with handmade transmitters that only weigh 5gm, an innovative product of the company Microwave Telemetry. The Great knot is under enormous pressure, affected by the loss of mudflats in the Yellow Sea in China, so this satellite tracking will give a detailed insight into how individual birds use the Yellow Sea and Roebuck Bay.
Chris Hassell, from the Global Flyway Network, brings the latest news from China on migratory shorebird habitats, under threat from development. There's a glimmer of hope, with the strong involvement of World Wildlife Fund (WWF) China and Wetlands International in efforts to conserve sufficient of the wetlands for migratory shorebirds use.
