NANCHANG, Sept. 20 (Xinhua) -- Observers have spotted the first of this year's migratory birds at Poyang Lake, China's biggest freshwater lake.
Wen Sibiao of the Jiangxi Poyang Lake National Nature Reserve, said Tuesday that more than 500 birds had showed up at the reserve, seven days earlier than last year.
"Five species have been seen so far," Wen said.
Huge flocks of migratory birds will soon arrive at the lake as the high water season there comes to an end.
About 95 percent of the world's white crane population spend winter at the lake.
