The mitochondrial cytochrome b gene of the Korean subspecies (Falco tinnunculus interstinctus) of the common kestrel has been analyzed. According to the molecular phylogeny of six subspecies of common kestrel, six subspecies of the common kestrel were divided into two clades: the first clade is composed of the South African subspecies (F. t. rupicolus) and the second clade includes 5 subspecies (F. t. tinnunculus, F. t. rufescens, F. t. interstinctus, F. t. canariensis and F. t. dacotiae) of the common kestrel. Korean subspecies, F. t. interstinctus was closely related to F. t. rufescens and original subspecies F. t. tinnunculus.

A common kestrel (Falco tinnunculus) was presented with inability to stand and fly at Chungnam Wild Animal Rescue Center. The kestrel showed non-weight bearing ambulation on both legs and crepitation with no external wound. Radiographs revealed a fracture on mid-diaphysis of right tibiotarsus and a distal end fracture of left femur. Intramedullary pinning was chosen for reduction of both fractures. The right tibiotarsal fracture was corrected first, and left femur was repaired 5 days later. The kestrel was managed with a specially designed sling to prevent further iatrogenic damage for 2 weeks. Three weeks after the surgery, the kestrel was able to stand and found to perch in 4 weeks. On 5 weeks, The kestrel could fly free at outdoor aviary and was released through rehabilitation for 3 months finally.

The purpose of this study is to examine distribution and abundance of wintering raptors in Korea during 2000-2007 which is a rare data set for covering large landscape areas. Total 6,643 raptors of 16 species were recorded at 94 different points in west, south and east coasts, and rivers of inland areas all over Korea. During the study period, the most abundant raptors were black vulture (Aegypius monachus, 62.3%), common kestrel (Falco tinnunculus, 11.0%) and common buzzard (Buteo buteo, 10.0%), and these 3 birds were dominant species in inland areas and also considered as resident species except for black vulture. Also, there was a difference among 5 different habitat types. Black vultures were most found in estuaries whereas common buzzard and common kestrel could be found in coastal areas. Presumably raptors prefer reservoirs and estuaries probably due to lower human disturbance in these areas, and management efforts should be concentrated in inland areas for black vulture and coastal areas for common kestrel and common buzzard.

This study was carried out to propose the new procedure to apply Habitat Evaluation Procedure(HEP) of target species using delphi technique, which is suitable to develop endangered species with few researches and ecological knowledges. To identify habitat quality of specific species in development project site, we can develop habitat model and create habitat suitability maps. In this study, we select the Common Kestrel(Falco tinnunculus) as target species in four areas(Paju, Siheung, Ansan, Hwaseong) which is located near the Seoul metropolitan area. The Delphi technique was selected to get the reliable information on the species and habitats requirements. Through the delphi approach, seven habitat components were determined as suitable variables for the Common Kestrel: density($n/km^2$) of small mammals, area($km^2$) of bare-grounds, pasturelands and riparian, and open area(%), spatial distribution and area of croplands, landscape diversity, breeding sites(tall trees, cliffs, high-rise buildings), and the length of shelf. Habitat variables used in this model were classified into two categories: % of suitable land-cover type(open areas, croplands, pasturelands, wetlands, and baregrounds) and the quality of feeding sites(within 250m from edges of woodlands). Habitat quality of the Common Kestrel was assessed against occurred sites derived from the nationwide survey. Predicted habitat suitability map were closely related to the observed sites of the endangered avian species in the study areas. With the habitat suitability map of the Common Kestrel, we assess the environmental impacts with habitat loss after development project in environmental impact assessment.

동물의 번식 성공에 가장 큰 요인은 먹이의 선택이고 먹이의 선택은 서식지의 질과 양에 의해 결정되어 지며, 생물량이 높은 습지의 경우 생태계 기능의 지표로서 황조롱이의 사냥 장소의 선택은 서식 장소의 질과 양을 알아보는 중요한 단서가 될 것으로 예상된다. 본 연구는 충남 공주시 유구읍의 황조롱이 사냥장소에 대해 4가지 유형(초지, 논, 밭, 하천변)으로 구분하여, 번식시기인 3월에서 6월까지 3년간 (2014년~2016년) 황조롱이의 행동을 기록하였다. 조사결과, 사냥의 장소는 하천변에서 높은 사냥행동을 보였고, 비행사냥은 5월과 6월에 많이 하는 것으로 조사되었다. 또한 비행사냥의 주요 획득 먹이는 포유류(쥐), 착지행동의 주요 획득 먹이는 곤충류로 조사되었다. 이에 따라, 하천변에서는 주로 비행사냥이 이루어졌으며, 초지나 논과 밭에서는 착지 행동이 비행행동에 비해 높게 조사되었다. 사냥이 이루어지는 지점의 식물이 땅을 덮는 피도는 사냥지역별 차이를 보였으나 식물의 높이는 차이를 보이지 않는 것으로 확인되었고, 사냥 방법에 따른 식물의 높이는 포유류(쥐)를 잡기 위한 비행사냥이 착지사냥보다 낮은 높이를 선호하는 것으로 분석되었다. 이러한 결과들을 바탕으로 황조롱이의 번식기 먹이 선택에서 하천변은 매우 중요한 환경 요소로 판단된다.

A common kestrel was admitted to Chungnam wild animal rescue center, having been unable to fly. On the physical examination, the bird was presented with contusion and swelling on its right humerus closed fraction and had pain response. Radiographic examination was explicitly revealed closed fracture on right proximal humerus. Its closed fracture was reduced with tie-in fixator and figure-of-eight tension band, and inserted pins on its right humerus surgery were removed on the $14^{th}$ day after the surgery. As Falco tinnunculus was able to move its wings from Day $21^{st}$ day, its rehabilitation was done at outdoor facility and it was successfully released. Proximal humerus reduction with tie-in fixator and the wire was a success, and this treatment with reference to this study will be surely effective to support the other wildbird's reduction stability.

The current study analyzed the home range size of the Common Kestrel (Falco tinnunculus) by observation using the natural markings in the suburban area of Busan from December 2009 to May 2010. In all, 26 individual kestrels were observed in the study area, of which 14 individual kestrels were frequently observed (more than five times) and 12 were observed less frequently (less than five times). Mean home range sizes of the 14 frequently observed kestrels were estimated using two different methods (minimum convex polygon (MCP) method and fixed kernel (FK) method): 34.49 ha(2.74-163.96 ha) by 100% MCP, 41.35 ha(3.54-99.02 ha) by the 95% FK, 14.33 ha(0.20-31.57 ha) by the 75% FK and 5.75 ha(0.52-14.74 ha) by the 50% FK. The mean home range size was larger for males than for females estimated at 51.50 ha(15.04-163.96 ha) and 11.80ha(2.74-24.48 ha), respectively, by the 100 % MCP method and 8.02 ha(2.38-14.74 ha) and 2.72 ha (0.52-4.28 ha), respectively, by the 50 % Fixed Kernel method. The home range sizes by sexes in breeding pairs differed during the wintering and breeding seasons; the sizes decreased among females but increased among males during the breeding season. Such differences of home range sizes between sexes could be attributed to parental role division during the breeding season. Females stay in the nest or next to it during laying, incubating, and feeding activities, and males go far away from their nest sites to forage areas for their fledglings for most of the breeding period.

This survey aims to provide information on the pattern of distress in wild avian animals in Gangwon province. This survey is based on 315 wild avian which were rescued by the Kangwon University Wildlife Rescue Center. The data was collected at the Wildlife Animal Center from September 2007 to August 2010, and by analyzing the shape of the wild animals killed or injured, the center seeks an efficient and systematic way to manage such distress. There are 55 species found, in this study including 40 common kestrel, 34 eurasian eagles, 20 common buzzards, 20 collared scops owls, 19 oriental scops owls, 16 brown hawk owls and 160 others. These are the results of the survey: 129 (40.3%) of 315 avian birds were found between June and August. Many cases in that term were observed falling from the nest or losing their mother because of unskilled flight during the breeding season's flight practicing process. Between November and December, 64 individual (20.3%) were found, and it's the second largest number. The main reasons for these results were starvation and exhaustion from the winter migratory season. The results indicated that the main reason for avian distress came from the following: collision with architecture windows in 73 cases (23.2%), starvation and exhaustion in 63 cases (20.0%), collision with vehicles in 51 cases (16.2%), becoming orphaned in 69 cases (21.9%), trespassing into buildings occurred in 19 cases (6.0%), collision with electric wires in 18 cases (5.7%), poaching materials in 13 cases (4.1%), becoming entangled by fishing wire and other miscellaneous materials in 4 cases (1.3%), infection from parasites in 4 cases (1.3%), toxicosis from such toxins like agricultural chemicals in 1 case (0.3%). Overall, the purpose of this investigation was to analyze cases of avian distress in Korea's wildlife. This study used areas, seasons and causes to understand origins of these animals distress. So that it can be utilized for organized wild avian rescue and treatment.

Background: Rocuronium bromide has been evaluated as a mydriatic agent in birds, but the species applied were limited and the dose and effect were variable. Objective: This study aims to evaluate the efficacy of topical rocuronium bromide as mydriatics in 4 species according to horizontal palpebral fissure length: Feral pigeon (Columba livia), Common kestrel (Falco tinnunculus), Northern boobook (Ninox japonica), and Eurasian eagle owl (Bubo bubo). Methods: A total of 32 birds (8 for each species) were included as pre-releasing examination. Rocuronium bromide was instilled in one randomly selected eye of each bird based on palpebral fissure length criteria (0.5 mg/50 µL for pigeons, 1 mg/100 µL for kestrels and boobook owls, and 2 mg/200 µL for eagle owls). The contralateral eye was used as control and treated with normal saline. After instillation of the drug, pupil diameter, pupillary light reflex, intraocular pressure, heart rate, and respiratory rate were evaluated at 10 min intervals up to 180 min and at 30 min intervals up to 360 min. Results: Statistically significant mydriasis was obtained in all birds (p < 0.001). However, in boobook and eagle owls, marked mydriasis persisted until 360 min. Side effects including corneal erosion and lower eyelid paralysis were common, which was observed in 26/32 birds. Blepharospasm was also noted during this study. No systemic adverse signs were observed. Conclusions: Rocuronium bromide could be a good mydriatics option for 4 species of birds, however, further studies are needed to find lowest effective dose to reduce drug-related side effects.
