Beijing, October 8 (Youth.cn) - On a wetland beach in Liaoning, thousands of seagulls, cormorants, curlews and other migrant birds were flying over. As one of eight international bird-migrant-routes, near 80 species of migrant birds pass through this region every April to October. In the migrate season, 40 to 50 thousands of migrant birds pass by the wetland beach every day, forming splendid “bird wave” landscape. To better protect migrant birds, local forestry and grassland bureau are engaging in regular patrol at the region where birds fly by. Photo/VCG
