Abstract:
Based on the field survey of birds carried out from 2019 to 2021 and the historical records of bird distribution, 232 species of birds belonging to 17 orders and 45 families in Zoige Wetland National Nature Reserve were recorded and summarized in this research, including 31 species of birds in 7 orders and 15 families from literature review. There were 157, 40 and 35 species in the Palaearctic realm, Oriental realm and widespread birds, which are divided into 12 distribution types. The Palaearctic birds accounted for 67.67%. Among them, 98 were resident birds, 50 were migratory birds, 52 were summer migratory birds, 29 were winter migratory birds, and 3 were lost birds. Non-resident birds accounted for 57.76%. The seasonal variation of bird diversity is obvious. A large number of bird species were distributed in alpine meadow (165 species) and alpine shrub (127 species) habitats. Previous studies on birds in this area mainly focused on wetland habitats, mainly on waterfowl. It is suggested that more attention and research should be paid to birds in non-wetland habitats of nature reserves in the future, especially passerine birds and raptors. The distribution number, species and dominant species of birds were significantly different in different habitats, and the number of common species of birds was different in different habitats, which reflected the significant habitat differentiation on horizontal spatial gradient in this area in recent years. In recent years, the number of newly recorded birds in the reserve has been increasing, and the bird diversity of birds has become more and more complex. According to the results of this study, it is suggested that the protection measures for birds should be formulated according to seasons and habitat types in the future.
