The biggest factor in the success of breeding animals is selection of foods, which is determined by quality and quantity of habitats(Newton, 2003), in the case of This high biomass wetlands as an indicator of ecosystem function about Common Kestrel's choice of hunting area is expected to be an important clue of quality and quantity of habitats. For this study, it is divided into four types(Glasslands, Paddy fields, Dry fields, Rparian land) about Common Kestrel's hunting area in Yugu-eup, Gongju-si, Chungcheongnam-do, Recorded the behavior of Common Kestrel for three years during the breeding season from March to June(2014~2016). Result of investigation, hunting area showed a high hunting behavior in riversides and flight-hunting was frequently investigated from may to June. In addition flight-hunting's main food acquisition is mammal(the vole), while perching behavior's main food acquisition is insect according to the fact flight-hunting were mainly done in riversides, perching behavior were highly investigated than flight-hunting at glasslands and paddy fields and dry field. Hunting spot's coverage rate of plants covering the ground showed differences depending on hunting areas, but height of plants were not significant. Height of the plant according to hunting methods of flight-hunting to catch mammal(vole) was analyzed to prefer lower height than perching behavior Based on these results riversides are considered as a very important environmental factors for Common Kestrel's prey selection in breeding session.

In this study observation records of the National Natural Environment Survey (2008-2012, 2014-2017) and the Korean Natural History Research Information System (KNHRIS) for the common kestrel (2013-2016) were consulted to determine the correlation of the distribution of kestrels in an area and the area's land use type. Distribution characteristics were studied based on data collected over the last 10 years (2008-2017). Findings show that the common kestrel is widely distributed between 4,407 sites registered in KNHRIS in the period of 2008-2012, 3,899 sites in 2014-2017, and 508 sites in 2013-2016. Relationship analysis was conducted for the altitude and urban planning factors of statistics based on a 2017 GIS check to determine the distribution characteristics. The birds' altitude was confirmed to range from 0 to 1,200 metersck but was most commonly observed at less than 100 meters. Above 200 meters, the rate of occurrence decreased rapidly. The rate of occurrence of the common kestrel was highest in Chungcheongnam-do province, followed by Gyeongsangbuk-do, Kyonggi-do, Jeollanam-do and Jeollabuk-do. As urban areas, green areas, commercial areas, and industrial areas the presence of swere positively correlated with the presence of kestrels, the rate of occurrence of the kestrel was higher in those regions. However, there was no significant relationship between the incidence of kestrels and housing construction or residential areas.

To classify the relationship between riparian vegetation type and bird habitat, we studied the vegetation and avian species in the three streams(Anyang Stream, Gap Stream, Seom River), located in middle province. Five different vegetation types - Woodland type, Shrub type, Tall and wet grassland type, Low and dry grassland type and Cropland - were identified. The habitats of avian species were highly correlated with vegetation type. Streptopelia orientalis and Hypsipetes amaurotis were found in woodland. Both Paradoxornis webbiana and Phoenicurus auroreus were mainly found in shrub. Tall and wet grassland were preference habitats of Ixobrychus sinensis, Acrocephalus arundinaceus, while, low and dry grassland were occupied by Phasianus colchicus, Falco tinnunculus. Cropland were used as breeding and feeding sites for Egretta alba modesta, Anas poecilorhyncha, Anthus spinoletta. Distribution patterns of avian species were clearly divided by vegetation type and site characteristics in the stream.

Within the scope that does not interfere with the performance of basic duty, the military has been actively supporting the national policy for the conservation of the natural environment in accordance with the "military environmental protection guidelines". Since there is a lack of information regarding inhabitation for wild fauna and flora, field investigations of the natural environment at Jinhae local unit were performed three times in 2003. As a result of the investigation, lycoris sanguinea as flora, marten, otter, and leopard cat as mammalia, and accipiter soloensis, accipiter gentilis schvedow, accipiter gularis, buteo hemilasius, falco tinnunculus and terpsiphone atrocaudata as bird were confirmed to inhabit. For the conservation of the natural ecosystem, the expansion of research for natural ecosystems within the military unit is required. Additionally, environmental pollution can be prevented through the proper maintenance of basic environmental facilities including sewage treatment facilities, soil pollution control facilities, and waste storage facilities. In cooperation with local governments and private organizations, the natural cleansing action and sustainable wildlife conservation should be expanded.

This study was conducted in order to analysis the forest fire effect to the raptors habitating in and around the large forest fire occurred area, Goseong country, Gangwon province, Korea. There were observed raptor birds belonging to 8 species, 3 families, and 2 orders in the survey area. The most dominant species was Eurasian Hobby(Falco subbuteo), which was followed by Common Buzzard(Buteo buteo), Kestrel(Faico tinnunculus) and Chinese Sparrow Hawk(Accipiter soloensis). The largest number of species and individuals were observed in May 2002. In partially undamaged areas and undamaged areas, five species of rapacious birds were observed, which was the largest number of species observed. If an environment where rapacious birds can build nests is created in forest fire damaged area in order to raise the number of species and population, the number of species and population of rapacious birds living in the forest fire damaged area will grow further.

This study was conducted to investigate the status of carcasses of wild birds among natural monuments in Korea. In Korea, from 2016 to 2020, a total of 38 species and 5,036 individual carcasses of natural monuments were found. The year 2020 saw the highest numbers of species death with 34 and in 2019 the highest number was recorded with 1,095 individuals. In autumn, the largest number of species and the smallest number of individuals were confirmed dead. On the contrary, the smallest number of species and the highest number of individuals were confirmed dead in summer. The largest number of species died in November, and the largest number of individuals died in June. Kestrels accounted for about 20% of the total carcasses, making up the largest number, followed by eagle owls, brown hawk-owls, scops owls, goshawk, eagles and sparrow hawks. In spring and summer, domestic breeding species accounted for most of the carcasses and in winter, the proportion of overwintering individuals such as wooper swans and eagles increased. Reports of lost natural monuments are done by human and the status of the carcasses alone cannot inform the population characteristics of natural monuments when they stay in Korea. However, it is expected that the identified domestic population of strigiformes which has not been investigated in detail because they are nocturnal, and data on the status of carcasses of natural monuments in Korea will provide basic data for the protection of natural monuments.

Among Natural monument birds, a total of 11 species and 2,209 individuals were found in Nakdong river estuary from March 2007 to February 2008 including Eurasian Oystereacher (Haematopus ostralegus; No. 326), Mandarin Duck (Aix galericulata; No.327), Tundra Swan (Cygnus columbianus; No.201-1), Whooper Swan (Cygnus cygnus; No.201-2), Black-faced Spoonbilll (Platalea minor; No.205-1), Eurasian Spoonbill (Platalea leucorodia ; No.205-2), Steller's Sea Eagle (Haliaeetus pelagicus; No.243-3), White-tailed Sea Eagle (Haliaeetus albicilla ; No.243-4), Hen Harrier (Circus cyaneus; No.323-6), Common Kestrel (Falco tinnunculus; No.323-8) and Swan Goose (Anser cygnoides; No.325-1). Among the habitats for migratory birds in Korea, the Nakdong river estuary is the only place where more than 2,000 individuals of Whooper Swan(Cygnus cygnus) spend winter. Eulsukdo, Myeongji Flat and neighboring tidal flats (Myeonggeummeori, Baikhapdeung, Doyodeung, Jangjado, etc.) are major habitats for natural monument birds such as Eurasian Spoonbill(Platalea leucorodia ), Whooper Swan(Cygnus cygnus) and Swan Goose(Anser cygnoides). A colony of aquatic plants such as Common Bulrush(Scirpus triqueter) and Common Reed(Phragmites communis) serves as a feeding and resting place for birds in the Anatidae family including ducks, swans and geese. Plans for management and conservation of the habitats and the natural monument birds in Nakdong river estuary are as follows: minimization of water contamination, construction and management of aquatic plants habitats, protection of sandbanks, security of stable habitats, and consistent monitoring.
