Two woodpeckers fight for territory by the Wolong Lake in Kangping County, Shenyang City in northeast China's Liaoning Province.

The grey-headed woodpecker (Picus canus) is widespread but hard to find due to its vigilance, while the great spotted woodpecker (Dendocopos major) is the most common woodpecker in China.

Wolong Lake ecological zone is the first ecological pilot zone in north China. It is home to over 800 wildlife species and one of China's largest freshwater wetland parks.
