Analysis of Bird Diversity in Qingtian Turtle Provincial Nature Reserve,Zhejiang
From April of 2022 to March of 2023,we investigated the bird diversity in Qingtian Turtle Provincial Nature Reserve by using the transect method.A total of 76 bird species of 36 families,12 orders were recorded,including 7 species of national second-class key protected birds and 4 species of near threatened(NT)species.In terms of residence types,there were 49 species of resident birds,16 species of winter migratory birds,8 species of summer migratory birds and 3 species of traveling birds.In terms of faunal types,there were 44 species of orien-tal birds,29 species of palaearctic birds,and 3 species of widely distributed birds.The bird ecotype in reserve was dominated by the song-birds,45 species were recorded.Shannon Wiener diversity index,Simpson dominance index and Pielou evenness index in the winter were the largest,and Margalef richness index in the autumn was the largest.The four indices in the summer were all the smallest.This study systemati-cally analyzed the diversity characteristics of bird communities in the reserve,which provided scientific references for further protection and management in the reserve.
