Bird Diversity in the Home Range of the Released Crested Ibis Nipponia nippon in Deqing,Zhejiang Province
In order to understand the bird diversity and community dynamics in the home range of the released Crested Ibis Nipponia nippon in Deqing,Zhejiang,and to explore the main associated birds of Crested Ibis and their interspecific relationships,we conducted a bird resource survey in June 2023 and January 2024 using the line transect method and sample point method.A total of 155 species of birds belonging to 15 orders and 47 families were recorded,including 2 species of national first-class key protected wild animals,14 species of national second-class key protected wild animals,and 20 species of key protected birds of Zhejiang Province.There are 63 species of birds from the Palearctic realm,53 species of birds from the Oriental realm,and the rest are widely distributed species.There are 71 species of resident birds,31 species of passing birds,30 species of winter migratory birds,and 23 species of summer migratory birds.A total of 117 species of wild birds were recorded in summer,with a total count of 3 711 birds,and the dominant species was Little Egret.A total of 89 species of wild birds were recorded in winter,with a total count of 3 209 birds,and the dominant species were Egretta garzetta and Passer montanus.Among the six survey areas,the number of species and the number of individuals in Tangjing village area were the highest in summer and winter,and the number of species and diversity index H'in the Dengta village and Lianhe village area were at the lower level in summer and winter.The survey found that there was competition between Ardeidae birds and Crested Ibis in terms of food resources and nesting sites,and raptors and corvids had a certain impact on the survival and reproduction of Crested Ibis.Further research is needed on the mechanism of the impact of these companion birds on the Crested Ibis,as well as its management and control measures.The results of this study provide basic data for the conservation of local bird diversity and the released population of Crested Ibis.
