A new study has suggested that migratory songbirds in East Asia are in trouble, and has called for national action and international co-operation to deal with the threats posed.
The study reveals that several migratory songbirds are declining in the East Asian-Australasian Flyway, owing to a range of threats across many countries. …
The East Asian-Australasian Flyway, running from Siberia and Alaska down to South-East Asia and Australia, supports the greatest diversity of migratory birds on the planet, with 170 long-distance migrant songbirds and more than 80 short-distance migrants…..
Currently available evidence suggests that habitat loss and hunting are the two most significant threats on the East Asia flyway. Other problems such as invasive species, climate change and collision with man-made structures can also have a big impact.
Some species, like the Vulnerable Izu Leaf-warbler and Pleske’s Grasshopper Warbler, are particularly at risk due to their small breeding ranges and because their entire wintering ranges remain unknown to scientists – thus hampering effective conservation. The Endangered Yellow-breasted Bunting used to be abundant, but has drastically declined as large numbers are trapped annually for food in South-East Asia and southern China.
