Photo taken on Oct. 24, 2009 shows the charming autumn scenery of a bevy of birds flying over the expansive everglade by Poyang Lake, the largest fresh water lake of the country, at Wucheng Town, Yongxiu County, east China's Jiangxi Province. Local ecological ambience keeps on ameliorating thanks to serial effective measures on grazing forbidden, restoration of reclaimed farmland, etc. [Xinhua]
