Abstract
The survey was conducted in five areas including Namsan district (21.00 ㎢), Tohamsan district (76.95 ㎢), Seoak district (4.30 ㎢), Hwarang district (3.90 ㎢), and Sogumgang district (6.8 ㎢) that are designated as Gyeongju National Park. The bird population in the forests and surrounding areas was examined through surveys performed three times in June, August, and January 2017. A total of 36 families, 88 species, and 7,724 individuals of birds were observed, and the dominant species were Passer montanus (19.43%), Corvus frugilegus (10.97%), Anas poecilorhyncha (8.08%), Streptopelia orientalis (7.65%), Paradoxornis webbianus (6.59%), and Microscelis amaurotis (5.80%). The number of bird species observed during the survey was the highest in the spring with 60 species, 50 species in summer, and the lowest in the winter with 45 species. The number of species, population, species diversity, and species richness of birds in Gyeongju National Park have been increasing compared with those observed 20 years ago.
