A Study On the Bird Community in Chilgap Mountain Provincial Park

In this result, from May, 2007 to January, 2008, important points for bird habitation in Mt. Chilgap Provincial Park area (Cheonjang reservoir, climbing paths of Mt. Chilgap, Chilgap reservoir, and Janggok temple, etc.) were established and investigated once every season. It was found that observed birds were 65species-4,999 individuals and dominant species were Anas poecilorhyncha(926 individuals, 18.52%), Emberiza elegans (553 individuals, 11.06%), Anas platyrhynchos (504 individuals, 10.08%), Paradoxornis webbianus (420 individuals, 8.40%), Passer montanus (358 individuals, 7.16%) (Table 1). By migratory features of birds, it was found that they were 29 species of resident birds (44.62%), 22 species of winter migratory birds (33.85%), 12 species of summer migratory birds (18.46%), and 2 species of passage birds (s3.08%). By seasons, it was found that there were 48 species-680 individuals in spring, 32 species-530 individuals in summer, 35 species-1,616 individuals in autumn, and 38 species-2200 individuals in winter. By investigation areas, it was found that there were 45 species-1,444 individuals in A area, 49 species-2,691 individuals in B areas, and 41 species-64 individuals in C area. The overall species diversity was 3.02. It was found that the species diversity indexes by seasons were 3.31 in spring, 2.79 in summer, 2.72 in autumn, and 2.52 in winter, and they were 3.05 in A area, 2.50 in B area, and 2.98 in C area, by areas. As endangered species, 7 species including Aix galericulata, Anas formosa, Accipiter soloensis, Accipiter gentilis, Buteo buteo, Falco tinnunculus, and Charadrius placidus were observed.
