The total number of individual birds observed in Ulleung Island was 5,692 and they consisted of 67 species of the 38 families belonging to 12 orders. In June, 5,091 individuals of 42 species were observed, and 2,099 individuals of 46 species in September. There were less individuals but more species in September and in June. At each region, 914 individuals (sum of the maximum count) of 37 species were observed at Nari Basin and Sunginbong. The dominant species were Carduelis sinica (35.78%), Passer rutilans (22.98%), Apus pacificus (5.47%), Hirundo rustica (4.38%), etc. In trekking trail areas, 1,063 individuals (sum of the maximum count) of 40 species were observed, which was more than those in Sunginbong. The dominant species were Passer rutilans (26.06%), Carduelis sinica (20.04%), Parus major (10.72%), Apus pacificus (7.62%), etc. In coastal area, 3,929 individuals (sum of the maximum count) of 48 species were observed. There were the largest number of species and individuals. The dominant species were Larus crassirostris (79.10%), Passer rutilans (5.45%), Apus pacificus (3.56%), etc. Through the addition of the newly observed 20 species in this research to the previous studies, the recorded birds in total in Ulleung Island were 112 species of 38 families belonging to 16 orders. Keywords: Dominant species, Nari Basin, Sunginbong Introduction Ulleung Island, located at 37 o 33' north latitude and 130 o 47' east longitude, has an area of km 2. It is about km away from Jukbyeon-eup, Uljin-gun, Gyeongbuk and 87.4 km from Dokdo Islet. The topography of the island features volcanic and coastal landforms. Also, salt weathering produces distinctive topographic forms of the island. There is Sunginbong (984 m above the sea level) in the middle of the island. Ulleung Island, a tholoide (bellshaped volcano), is almost steep-sided so that it has few flatland and monotonous shorelines, except for Nari Basin north of Seonginbong, which is a caldera basin with a diameter of 3.5 km and the largest flat area on the island. In particular, Sunginbong virgin forests, Nari Basin, and Bongrae Falls represent the natural landscape unique to Ulleung Island (Ulleung-gun, 2007). Moreover, the island has its important value for academic research and tourist attractions because of the distinctive fauna of its inhabitants *To whom correspondence should be addressed. Tel: paekwk@msip.go.kr (Hahm et al., 1993). However, due to the factors such as the increasing number of tourists, the development of residential area, and the construction of hiking path around the seashore, the ecosystem of Ulleung Island has been expected to be changed. According to the previous study of the bird fauna in Ulleung Island, Woo and Koo (1981) reported 31 species in Ulleung Island and 17 species in Dokdo Islet. Hahm et al. (1993) reported 24 species in Taeharyong in summer. Yoon and Yoon (1996) recorded 32 species in summer. Kim and Nam (2001) reported 45 species in Ulleung Island and 11 species in Dokdo Islet. Park et al. (2009) reported 38 species in Nari Basin areas. In addition, Hur et al. (2009) investigated the morphological characters of Parus major in Ulleung Island, the central area of Korean peninsula, and Jeju Island. They reported there was no difference between the subspecies of Parus major in each site. As a joint survey of National Biodiversity Union, the present study investigated the comprehensive fauna in Ulleung Island. This study also aimed to use those findings from this study as the basic resources for conserving and anticipating the possible changes of ecosystem of the island.

Materials and Methods Research Site Ulleung Island is a pentagon-shaped island formed by volcanic eruptions. It is 10 km from east to west and 9.5 km from north to south, with a total of 56.5 km of shorelines. It consists of a total of 44 islands, including 4 inhabited islands and 44 uninhabited islands. About 76% of the area is forest land, and only 18% is farmland used as upland field. There are significant plant communities designated as natural monuments, including the natural growing sites of Chinese juniper in Tonggumi and Daepunggam, hemlock, pine and beech trees in Taeha-dong, evergreen broadleaved trees (camellia, laurel, Japanese aucuba, silver magnolia), and southern plants (Ligularia tussilaginea, Goodyera spp., Goodyera maximowicziana Makino, etc.) (Ulleung-gun, 2007). Survey Method Based on the survey methods of Line transect census (Bibby et al., 1992) and Point census, the survey of bird community was conducted by moving along the roads, forest roads, and trails, which were divided into Nari Basin and Sunginbong areas (A), trekking trail areas (B), and coastal areas (C) in Ulleung Island. Bird species and individuals were identified by using binoculars (Nikon 10 50), with naked eyes, and the crying sound of the observed birds. The points of observation were recorded by using GPS (Gamin 60CS). The list of survey findings was based on Checklist of the Birds of Korea (The Ornithological Society of Korea 2009). Based on Won s (1981) Illustration flora & fauna of Korea. vol. 25 avifauna and A Field Guide to the Birds of Korea (Lee et al., 2000), the findings were listed by area. Analysis Methods The analysis of bird community was based on the formulas of Relative species density (RD) (Brower et al., 1990), Species diversity (Shannon and Weaver, 1965), and Species richness (Marglef, 1963). RD (Relative species density)=(ni/n) 100 ni: number of i species N: total number of individuals H' (Species diversity)= Σ (ni/n) ln (ni/n) ni: number of i species N: total number of individuals in an area Da (Species richness)=(s 1)/ln(N) s: total number of species N: total number of observed individuals Results and Discussion Bird Fauna of Ulleung Island The faunal survey of birds in Ulleung Island, conducted

3 Characteristics of Birds Community in Ulleung Island, Korea 177 twice from June 25 to 29 and from September 3 to 9, 2012, the total number of observed individual birds was 5,692 (sum of the maximum count) and they consisted of 67 species of the 38 families belonging to 12 orders (Table 1). In June (summer), 5,091 individuals of 42 species were observed, and 2,099 individuals of 46 species in September (fall). There were less number of individuals observed in September. However, there were a number of species because of a variety of the wading birds migrating in spring and fall were observed (Table 1). As Ulleung Island, an island in East Sea, plays an important role as a stopover and breeding site for migratory birds, there are relatively more number of species in spring and fall when they migrate, rather than that during the reproduction period. Moreover, it is characterized that there is the extremely high proportion of migratory birds, rather than resident birds (Park et al. 2012). With regard to the status of the dominant species in each period, Larus crassirostris (61.48%) was the most dominant species in June, followed by Passer rutilans (8.13%), Carduelis sinica (6.64%), and Apus pacificus (4.91%). In September, Passer rutilans (32.02%) was the most dominant species, followed by Carduelis sinica (22.63%), Larus crassirostris (10.01%), Parus major (5.57%), and Columba janthina (4.81%). Except for Apus pacificus, which are summer migratory birds, all resident birds were dominant species (Fig. 2). In breeding season in June, the density of population was very high because Larus crassirostris breed in group at the rocky coastal areas of Ulleung Island and Dokdo. On the other hand, the density was low in migrating period in September. This might result from the fact that they were dispersed into East Sea areas. The overall numbers of individuals (Passer rutilans, Carduelis sinica, Columba janthina, etc.) increased in September when drifting seaweeds became increasing after they bred. Park et al. (2012) argued that seven (excluding Larus crassirostris, Microscelis amaurotis, Parus major) out of top 10 dominant species observed in Ulleung Island were migratory birds. In the present study, however, resident birds, such as Larus crassirostris, Passer rutilans, Carduelis sinica, Parus major, Columba janthina, Monticola solitarius philippensis, Microscelis amaurotis, etc., were ranked as dominant species. In contrast, the relative species density of migratory birds were low. This might result from the difference of research ranges and periods. In each period, species diversity and species richness in June were 1.69 and 4.80, respectively, which were lower than those (2.33 and 5.88, respectively) in September (Table 1). This might result from the fact that the overall species diversity decreased because the number of species in June was larger than in September. Additionally, the extremely high density of Larus crassirostris breeding in group also caused the overall decrease of species diversity. Table 1.

Nari Basin has favorable environments for bird inhabitation due to less influence from wind, dense forests, and the soil suitable for cultivation (Park et al. 2009). 914 individuals (sum of the maximum count) of 37 species were observed at Nari Basin and Sunginbong. The

5 Characteristics of Birds Community in Ulleung Island, Korea 179 Fig. 2. Dominance of bird species of June and September in Ulleung Island dominant species were Carduelis sinica (35.78%), Passer rutilans (22.98%), Apus pacificus (5.47%), Hirundo rustica (4.38%), etc. In June, 369 individuals of 27 species were observed, and 736 individuals of 25 species in September. There were less individuals but more species in September. The overall numbers of individuals (Passer rutilans, Carduelis sinica, etc.) increased in September when drifting seaweeds became increasing after they bred (Table 2). In each period at Nari Basin and Sunginbong areas, species diversity and species richness in June were 2.86 and 4.40, respectively, which were higher than those (1.74 and 3.64, respectively) in September. This might result from the fact that the observed number of species in June was more than that in September. Additionally, the overall species diversity increased due to the relatively small difference among the numbers of each species. 2) Trekking trail areas (Dulre Path areas) The Dulre Path in Ulleung Island is trekking trail (Namyang to Taehayeong, Seokpo to Naesugeon), consisting of valleys and forests. The birds observed in the Dulre Path areas were a total of 40 species 1,063 individuals (sum of the maximum count). The dominant species were Passer rutilans (26.06%), followed by Carduelis sinica (20.04%), Parus major (10.72%), and Apus pacificus (7.62%). In June, 992 individuals of 29 species were observed, and 606 individuals of 27 species in September. Both numbers of species and individuals decreased in September. Species diversity in June and September were 2.37 and 2.15 respectively, which shows a little high in June. Species richness, however, indicates that the species richness in both June and September was the same (4.06), which shows that there was no significant difference in species richness between two periods (Table 3). 3) Coastal areas The coastal areas in Ulleung Island is steep-sided and has monotonous shorelines. In such coastal area, 3,929 individuals (sum of the maximum count) of 48 species were observed. The dominant species were Larus crassirostris (79.10%), Passer rutilans (5.45%), Apus pacificus (3.56%), etc. In June, 3,730 individuals of 32 species were observed, and 757 individuals of 31 species in September. Both numbers of species and individuals was larger in June. However, there was no significant difference in the number of species. Species diversity in June and September were 2.37 and 2.15 respectively, which shows a little high in June. Species richness, however, indicates that the species richness in both June and September was the same (4.06), which shows that there was no significant difference in species richness between two periods (Table 3). The extremely high density of Larus crassirostris in June results from the fact that they breed in group from the coastal cliffs in Ulleung Island. Therefore, the overall decrease of species diversity in June was significantly low (0.87) due to the extremely high density of single species (Table 4). The Changes in the Composition of Species In comparison with the previous findings: 41 species (25 families, 13 orders) before the 1980s (Ulleung-gun, 2007), 31 species (20 families, 9 orders) in 1981 (Woo and Koo 1981), 24 species (17 families, 7 orders) in 1992 (Hahm et al. 1993), 32 species (22 families, 9 orders) in 1995 (Yoon and Yoon 1996), 45 species (25 families, 12 orders) in 2001 (Kim and Nam 2001), and 38 species (24 families, 13 orders) in 2007 (Park et al. 2009), this study recorded the largest number of birds of 67 species (28 families, 12 orders). Moreover, the newly observed birds in the study are 20, including Anas crecca, Egretta intermedia, Charadrius leschenaultii, Tringa nebularia, Calidris ruficollis, Calidris

Hence, the recorded birds in Ulleung Island so far are 112 species of 38 families belonging to 16 orders (Appendix 1). 42 species were not observed in this study. Of those, Ardea cinerea, Columba janthina, Streptopelia orientalis, Apus pacificus, Dendrocopos leucotos, Parus major, Parus varius, Hirundo rustica, Zosterops japonicus, Monticola solitarius philippensis, Passer rutilans, Motacilla alba leucopsis, and Carduelis sinica have been consistently observed after the 1980s. However, 29 species have been observed only once, including Coturnix japonica, Cygnus columbianus, Aix galericulata, Mergus serrator, Puffinus carneipes, Ixobrychus sinensis, Pandion haliaetus, Gallinula chloropus, Gallinago solitaria, Gallinago gallinago, Xenus cinereus, Calidris alba, Calidris subminuta, Larus vegae, Synthliboramphus antiquus, Caprimulgus indicus, Dendrocopos major, Lanius tigrinus, Lanius cristatus, Corvus macrorhynchos, Tarsiger cyanurus, Phoenicurus auroreus, Cinclus pallasii, Motacilla flava taivana, Anthus rubescens, Emberiza fucata, Emberiza rutila, Emberiza spodocephala spodocephala, Emberiza yessoensis, etc. As Ulleung Island is a stopover site for

However, the species which have been observed only once might migrate in an irregular way due to the factor such as weather. Columba janthina,natural Monuments 215, is a forest-dwelling bird but lives on the evergreen broad-leaved tree along the sea coast or at the islands of warm areas as a resident bird. The bird collectively with others eats fruits mainly on the silver magnolia (Kim and Nam 2001). It is estimated that over 100 individuals inhabit in Ulleung Island. Especially, the habitat of Columba janthina at Sadong in Ulleung Island is designated and protected as Natural Monument, 237.
