Diversity of Autumn Ringed Passerine Birds in Nanjian Fenghuang Mountain From 2018 to 2022
Taking the autumn ringed Passerine birds in Fenghuang Mountain Bird Ring Station from 2018 to 2022 as the research object,the number changes of family,genera,species and individual,as well as the diversity and similarity in different years were analyzed.The results showed that a total of 5084 birds of 126 species belonging to 55 genera and 24 families were identified during the five years of the order.The 6 dominant species were Ficedula albicilla(18.04%),Calliope calliope(8.95%),Lanius cristatus(7.30%),Larvivora cyane(7.02%),Anthus hodgsoni(5.47%),and Turdus dissimilis(5.19%).The bird diversity index H was 3.4284,the uniformity index J was 0.7089,the dominance index C was 0.064 3,the concentration index C4 was 0.4131,the DF index was 9.4485,the DG index was 3.7283,and the G-F index was 0.6054.The diversity index and evenness index had little difference between dif-ferent years.The highest similarity coefficient was 0.761 9,and the lowest was 0.686 4.The similarity degree between different years was high,indicating that the composition of Passerine bird species in dif-ferent annual migration routes in Fenghuang Mountain was generally stable.There were 6 species of wild birds under national second-class state key protection,and 8 species of birds listed in the Red List of China's Vertebrates.In order to better protect the birds migrating through Fenghuang Mountain,some pro-tection and management suggestions were put forward.
