Niaoshan

　　    Niaoshan is situated to the west of Erlingou in Sanhe Township, spanning approximately 1,500 acres. It is a natural bird sanctuary, featuring dense forests and good concealment. Additionally, it borders the Han River to the north, the Nansha River to the west, and the Yangu River to the east, with crisscrossing ditches and ponds spread throughout the area. The abundance of fish and shrimp makes it an ideal habitat, which is why many birds favor this place for nesting and breeding.

　　    Over 30,000 egrets gather on the mountain. The purity of the bird species, their large numbers, and their concentrated habitat are rare in China.
