This study was analyzed between actual vegetation type and 4 Paridaes of Korea (Great tit Parus major minor, Marsh tit P. palustris hellmayri, Coal tit P. ater amurensis, Varied tit P. varius varius) in the urban forests in Seoul. The population size of total Paridaes was highest in Robinia pseudoacacia community. When supposed the same area for revision of the difference of each type, the population size was highest in Alnus hirsuta community. The next orders of total observed population was Alnus hirsuta - Pinus desniflora - Quercus acutissima - Castanea crenata. In the urban forest, Paridaes are looks not affected by the naturality of vegetation but other key figure.

This study was to investigate the user's effects on the avifauna in Sokri Mountain National Park. The survey was carried over 4 districts which were divided with main trail(valley, ridge), subtrail(ridge), un-used trail (valley) by line transect method from December 1989 to October 1990. The observed birds were 36 species and 570 individuals, these consist of 23 species for residents. 7 species for summer visitor. 2 species for winter visitor, 4 species for passage migrant. The average density of birds was 2.35 ea/ha., and main dominant species were Parus major minor, Porus palustris hellmayri, Parus varius varius and Sitta europaea amurensis in order. The observed frequency of wild birds was 3.4 times/km in average. No. of species, species diversity and observed frequency of summer and autumn were lower than winter and spring in 4 survey routes. Therefore, from now, in Sokri Mountain National Park manegement, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods of wild birds protection, especially in summer.

This study was conducted to investigate the user's effects on the avifauna in Kaya Mountain National Park. The survey was carried over 3 districts which were divided with main trail(valley), subtrail(valley), unused trail(ridge) by line transect method from April to October 1989. The observed birds were 29 species and 527 individuals. these consist of 20 species for residents, 7 species for summer visitor 1 species for winter visitor, 1 species for passage migrant. The average density of birds was 2.44 ea/ha, and main dominant species were Parus major minor, Garrulus gtandarius brandtii, Parus palustris hellmayri, Parus varius and Sitta europaea amurenis in order. The observed frequency of wild birds was 8.42 times/km in average. No. of species, no. of individuals, density, species diversity and observed frequency of summer were lower than spring in 3 survey routes. Therefore, from now, in Kaya Mountain National Park management, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods for wild birds protection, especially in summer. To investigate the use or not of artificial nests, 35 artificial nests were selected. The results of this survey showed that many wild birds prefered mixed nest in column shaped to wooden nests. The rightful installation and manegement for invitation and increase of wild birds was necessary.

Cheju island had that a fresh water Pisces composed of 9 Orders, 12Families, 24 Species, Amphibians composed of 2 Orders, 6 Families, 9 Species, Reptiles composed of 2 Suborders, 5 Families, 10 Species, Aves composed of 18 Orders, 49 Families, 236 Species and Mammalian composed of 6 Oredrs, 9 Families, 16 Species. So, total vertebrate's fauna were 35 Oredrs, 2 Suborders, 80 Families, 4 Subfamilies and 295 Species. Endemic species of the Cheju island were Mustela sibirica quelpartis, Apodemus agrarius vhejuensis, Micromys minutus hertigi and Crocidura russula quelpartis, Ageithalos caudatus trivirgatus, Sitta europaea bedfordi, Eophona personata personata and Dendrocopos oeucotos quelpartis, Troglodytes troglodytes fumigatus, Parus major minor, Cettia diphone cantans and Hynobius leechii quelpartis. Especially, Sibynoghis collaris and Anguilla mauritiana were only habitated in the Cheju island. And the Cheju island was formed in extending from Plieocene to Pleistocene. Differentiation of species was continued by geological isolation 0.3 million years that repeating glacial epoch and interglacial epoch.

Rapid urbanization around the world has negatively affected wildlife habitats, including birds. Wild birds settled in the city are adapting to the changed surroundings, and are typically known to make nests using materials that are easy to find around the city. This study was conducted for the purpose of analyzing the nesting materials on the Paridae using artificial bird nests installed in cities. In this study, the researchers established a total of 33 artificial bird nests in urban parks (22) and forests (11) in Cheonan-si, Chungcheongnam-do. Then we collected 4 artificial bird nests in urban parks (18.19%) and 5 in urban forests (45.46%) to compare the characteristics of bird nest materials by the nest, species, and urban green area types. Eight nests, excluding a nest abandoned by a pair of Paridae, were used for the material analysis. The collected nests were dried, and classified into natural materials (vegetable materials, animal materials, moss, and soil) and artificial materials (cotton, paper pieces, plastics, vinyl, and synthetic fibers), and then each nest was weighed. The classification result shows that the portion of moss (50.65%) was the highest in all nests, followed by soil (21.43%), artificial material (13.95%), vegetable material (5.78%), animal material (4.57%), and others (3.59%) in that order. Artificial materials were used in all nests in urban green areas. Moreover, although the Paridae used about 5.16% more vegetable material than the Parus varius, it was not significant (t=2.17, p=0.07). Plant materials and soil were most preferred in urban forests, and moss, animal, and artificial materials were widely used in that order in urban parks. There was a significant difference in the use of vegetable materials between urban parks and urban forests (t=3.07, p<0.05^*). In the habitats like urbanized and dry areas, where artificial materials are highly accessible, artificial materials replaced some roles of natural materials. This study is a basic study for the analysis of the types of materials used in artificial bird nests to understand the habitat system of urban ecosystems. It can be used as the basic data for ecological studies and conservation of the Paridae species.

Heavy metals are one of the dangerous pollutants that threaten urban biodiversity due to their accumulation over a long period without being decomposed in vivo. Accordingly, there is a need for biological monitoring to compare accumulation concentrations in living organisms according to the degree of heavy metal exposure to evaluate heavy metal contamination in the air in urban areas. This study aims to examine the possibility of using nesting materials as heavy metal monitoring samples and determine the effects of heavy metals on Paridae. We installed 54 artificial nest boxes in the research areas that included campus green spaces (14), urban forests (11), and urban parks (29) on a university campus in Cheonan City, Chungcheongnam Province. The birds' use rate of artificial nest boxes was 11/14 (78.57%) in campus green spaces, 8/11 (72.72%) in urban forests, and 6/29 (20.68%) in urban parks. Moss materials were collected from collected nests, and the heavy metal accumulation characteristics of each type of urban green space and the effects of heavy metals on the success of fledging of Paridae were compared through heavy metal analysis. The analysis showed that the average concentrations of zinc and lead were 228.08±209.62 ㎍/dry g and 17.67 ± 6.72 ㎍/dry g, respectively. There was no significant difference in zinc concentration for each type of urban green space (Kruskal-Wallis test, p-value=0.28), but lead concentration showed a significant difference (Kruskal-Wallis test, p<0.05^*). Of the 21 Paridae, nests analyzed for heavy metals, fledging of birds was observed in 11 nests (52.38%). Fledging of birds observed in each urban green space type was 7 campus green spaces (77.78%), 6 in urban forests (85.71%), and 1 in urban park (20%), mainly in urban forests and green spaces on campus. Heavy metal concentrations were compared to check the effect of heavy metal accumulation on the successful fledging of Paridae, but there was no statistically significant difference (Zn: W=44, p-value=0.74, Pb: t=0.64676, df =7.2422, p-value=0.54). This study is a basic study using the nesting materials of Paridae as heavy metal monitoring samples, and it is determined that it can be used as basic data for non-invasive biological monitoring.
