A total of 50 bird species, along with historical records, were recorded in this area. Of them, 29 species were residents, 20 summer migrant species, and 1 vagrant. Three species, the black-necked crane (Grus nigricollis), bearded vulture (Gypaetus barbatus ), and golden eagle (Aquila chrysaetos ), are listed as categrory I of the national key protected animals, and 7 species including the saker falcon ( Falco cherrug), hobby ( F. subbuteo ) , common kestrel ( F. tinnunculus ) , peregrine falcon ( F. peregrinus ) , cinereous vulture ( Aegypius monachus), black kite (Milvus migrans), and upland buzzard (Buteo hemilasius) are category Ⅱ of national key protected animals. Of the birds along the railway line, nffous-necked snowfinch (Montifringillla ruficollis) and Hume's ground tit (Pseudopodoces humilis) are dominant species, each accounting for 23.2% and 12.0% of the total number respectively. The common species includes the common raven (Corvus corax) (7.4%), ruddy shelduck (Tadornaferruginea) (7.2%), white-winged snowfinch (M. nivalis) (6.9%), Slanford's snowfineh (M. blandfordi) (6.3%), and bareaded goose (Auser indicus) (6.0%).
