河南董寨自然保护区鸟类环志种群动态分析OA

To clarify the population dynamics and migration patterns of banded birds in Henan Dong-zhai National Nature Reserve,this study was conducted based on bird banding data collected from 7 conservation stations and 2 synchronous monitoring stations of the National Migratory Bird Migration Network in 2023,employing methods including population abundance analysis and historical compari-son of migration timing.The results showed that a total of 4,222 individuals belonging to 75 species,21 families,and 4 orders were banded throughout 2023,among which Passeriformes was the absolute dominant order(accounting for 99.08％of the total banded individuals).The dominant populations consisted of 5 species,including Parus major and Aegithalos concinnus with a total of 2,479 individu-als banded(58.72％of the total).These dominant species were concentrated in Qilichong Conserva-tion Station,which is characterized by high habitat heterogeneity.Among the 43 migratory bird spe-cies,21 exhibited variations of 10-30 days in migration timing compared with historical records.It can be concluded that the bird community in this region exhibits significant transitional characteristics,with the distribution of dominant species being closely coupled with habitat heterogeneity.Changes in migration timing are primarily influenced by the completeness of the banding period.This research provides data support for an integrated"habitat optimization-monitoring enhancement-community col-laboration"strategy for bird conservation in transitional zones.
