The results of the study on the avian fauna of the Taebaeksan (Mt.) region of the Seodeukbong of the BaekduDaegan between May and October of 2007 are as follows. A total of 1,831 individuals of 71 bird species were observed in the study sites, and based on the average of the highest number of individuals, the most dominant species was the Brambling (Fringilla montifringilla) at 28.6 individuals (21.8%), followed by the Yellow-throated bunting (Emberiza elegans) at 13.5 individuals (10.3%), Long-tailed tit (Aegithalos caudatus) at 11.6 individuals (8.8%), Brown-eared bulbul (Hypsipetes amaurotis) at 7.6 individuals (5.8%), Marsh tit (Parus palustris) at 6.9 individuals (5.3%) and the Great tit (Parus major) at 6.5 individuals (5.0%). This was followed by the dominance, in decreasing order, of the Jay (Garrulus glandarius) at 5.7 individuals (4.4%), Siberian blue robin (Luscinia cyane) at 4.1 individuals (3.2%), Nuthatch (Sitta europaea) at 3.9 individuals (3.0%), Varied tit (Parus varius) at 3.6 individuals (2.8%), Crowned willow warbler (Phylloscopus occipitalis) at 3.5 individuals (2.7%) and Arctic warbler (Phylloscopus borealis) at 2.9 individuals (2.2%). It is predicted that there is a need to assess the importance of this region through continuous monitoring of the protected region of the BaekduDaegan.
