New Bird Records in Jiangsu Province:Fringilla coelebs,Cyornis glaucicomans and Phylloscopus borealoides
Common chaffinch(Fringilla coelebs),Chinese blue flycatcher(Cyornis glaucicomans),and Sakhalin Leaf warbler(Phylloscopus borealoides)were recorded in Baojie Mountain Forest Park in Wuxi,Jiangsu Province in 2023.Through a thorough review of relevant literature and China Bird Report(http://www.birdreport.cn/),we confirmed that these three passerine birds represent new records in Jiangsu Province.Considering their original distributions,observation time,and residential types,we propose that F.coelebs is a straggler,C.glaucicomans is a regionally rare passing bird,and P.borealoides is a common passing bird in Jiangsu.These new findings provide fundamental data for further research on the distribution ranges and migration patterns of these avian species.
