Bird diversity is an important component of biodiversity.A relatively complete resource list of birds is necessary to understand the regional biodiversity and its distribution status.In more than 30 years since the Annals of Vertebrates in Ningxia,there have been reports of new records of bird distribution in Ningxia.The Classification and Distribution List of Birds in China(the forth edition)has established a new bird classifica-tion system in China.The bird resources in Ningxia lack the latest resource directory,which brings inconve-nience to relevant research work.Therefore,it is necessary to clarify the bird resources in Ningxia and establish a classification list.Based on the Classification and Distribution List of Birds in China(the forth edition)as the classification system,and the bird list in the Annals of Vertebrates in Ningxia as the reference,combined with the data of bird new records in Ningxia.The bird species list in Ningxia were summarized.The results showed that by the end of June 2023,there were 419 species(446 species and subspecies)of wild birds belonging to 204 genera,68 families,21 orders in Ningxia.There are 19 species of birds are listed in the first class of national protected birds,and 79 species of second class protected birds.Flora composition showed that there are 290 species of Upper Palaearctic birds(69.21％of the total species),45 species of Oriental species(10.74％),and 84 species of widely distributed species(20.05％).According to the IUCN assessment,there are 2 species of critically endangered(CR),5 species of endangered(EN),12 species of vulnerable(VU),and 14 species of near threatened(NT).Seven are listed in CITES Appendix Ⅰ and 21 are listed in Appendix Ⅱ.The G index,F index and G-F index of birds of Ningxia are 4.973 1,39.353 4 and 0.873 6,respectively.Bird species diversity is relatively rich.
