Bird Diversity in the Conghua Specified Equine Animal Epidemic Free Zone and the Buffer Zones
In order to understand the distribution,population characteristics,activity patterns,and migra-tion patterns of wild birds in the Conghua specified equine animal epidemic free zone and the buffer zones,i.e.9 districts including Conghua district as centre,seasonal wild bird survey was conducted using the line transect method from November 2021 to August 2022.A total of 146 species,belonging to 51 families,16 orders,was recorded.Among them,65.1%species were resident birds,21.9%were summer migrant,9.6%were winter migrant;68.5%birds were Oriental species,21.2%were Palaearctic species,and 10.3%were widespread species;17 species were listed in Grade Ⅱ key state-protected species,23 species in provincial protected birds,and 9 in Appendix Ⅱ of CITES.Seven species were dominant,including Zosterops simplex,Pycnonotus joco-sus,Pycnonotus sinensis,Hemixos castanonotus,Acridotheres cristatellus,Cecropis daurica,Hypsipetes leu-cocephalus.The population numbers in Conghua district and Zengcheng district were significantly higher than those in the other seven districts.According to cluster analysis results,Zengcheng district,out of the 8 buffer zones,shows the highest bird species similarity with Conghua district.
