SW China wetland sees migratory birds check in and check out

Since early November, Ruoergai Wetland in southwest China's Sichuan Province has seen tens of thousands of migratory birds "checking out" and "checking in" during the seasonal migration.

Birds such as black-necked cranes, bar-headed geese, ruddy shelducks have left Ruoergai, while brown-headed gulls, red-crested pochards and Eurasian coots have just arrived at the water.

The high-altitude wetland, one of the largest in the country, contains hundreds of lakes, big and small, and its soil is covered by a thick layer of peat accumulated of decayed vegetation.
