본 연구는 소백산 국립 공원을 대상으로 계절별 조류 군집을 밝히고, 이의 보호 및 관리를 위한 적절한 방안을 제시하기 위하여 실시되었다. 조사를 위하여 주등산로 3개소를 조사지로 선정하여, 1992년 2월부터 10월까지 4회에 걸쳐 야생조류 및 이의 서식에 미치는 인자를 조사했으며 그 결과는 다음과 같다. 조사지에서 조사기간동안 관찰된 야생조류는 텃새 31종, 여름철새 17종, 겨울철새 6종 그리고 나그네새 4종으로 총 9목 12과 58종이며 이중천연기념물 323호인 새매, 황조롱이와 324호인 소쩍새 그리고 242호인 까막딱다구리가 관찰되었고 위기 조류인 큰오색딱다구리와 되지빠귀가 발견되었다. (서식종수는 봄철 38종, 여름철 33종, 가을철 26종 그리고 겨울철 22종이었다). 번식 조류 군집 중 수동 및 관목층을 둥지로 이용하는 길드와 수관층에서 먹이자원을 이용하는 길드가 대부분이었다. 제 1조사구역의 해발 900m이후의 자연식생과 제 2조사구역의 철쭉군락을 포함한 초원지역은 야생조류의 보호를 위해 관리가 필요하다. 제 3조사구역은 다양한 종이 관찰되었는데 이는 이 지역이 과수원, 농경지, 개활지 등의 다양한 서식지를 포함하기 때문이라고 생각된다. 이 지역은 밀도 또한 높게 나타나서 국립공원에서 조류를 관찰할 수 있는 적당한 장소라고 생각된다. 가을과 겨울철에는 풍부한 먹이 공급을 위해 먹이식물 및 활엽수림 조성 관리가, 봄철과 여름철에는 성공적인 번식을 위해 이용객에 대한 관리가 필요하다.

Cinereous vulture (Aegypius monachus) is a large raptor that belongs to the family Accipitridae in the order Falconiformes. It is a migratory bird that returns to Mongolia after wintering in the Korean Peninsula. In February 2015, a cinereous vulture was rescued from Asan-si, Chungcheongnam-do Province as it could not fly. It was transferred to the Chungnam Wild Animal Rescue Center in Korea. It was found to have a closed fracture on the right radius through radiographic examination, a basic procedure. Surgery was performed at the fracture site using a shuttle pin and wire. After successful physical therapy and rehabilitation, the cinereous vulture was released in October 2015. A metal ring (150-00713) and wing tags (G/BL 3) were attached to the bird before its release for subsequent identification. Two years and 4 months later, in March 2018, the cinereous vulture was rescued and brought back to the center. It was diagnosed with secondary pesticide poisoning. After receiving treatment, a radiography test revealed no specific findings related to the previous fracture surgery. Considering that migratory birds travel long distances, it was confirmed that the treatment for reducing the fracture in the radius using a shuttle pin and a cerclage wire was suitable.

Lilium ${\times}$ formolongi was genetically engineered by Agrobacterium-mediated transformation with the plasmid pCrtZW-N8idi-crtEBIY, which contains seven enzyme genes under the regulation of the CaMV 35S promoter. In the transformants, ketocarotenoids were detected in both calli and leaves, which showed a strong orange color. In transgenic calli, the total amount of carotenoids [133.3 ${\mu}g/g$ fresh weight (FW)] was 26.1-fold higher than in wild-type calli. The chlorophyll content and photosynthetic efficiency in transgenic orange plantlets were significantly lowered; however, after several months of subculture, they had turned into plantlets with green leaves that showed significant increases in chlorophyll and photosynthetic efficiency. The total carotenoid contents in leaves of transgenic orange and green plantlets were quantified at 102.9 and 135.2 ${\mu}g/g$ FW, respectively, corresponding to 5.6- and 7.4-fold increases over the levels in the wild-type. Ketocarotenoids such as echinenone, canthaxanthin, 3'-hydroxyechinenone, 3-hydroxyechinenone, and astaxanthin were detected in both transgenic calli and orange leaves. A significant change in the type and composition of ketocarotenoids was observed during the transition from orange transgenic plantlets to green plantlets. Although 3'-hydroxyechinenone, 3-hydroxyechinenone, astaxanthin, and adonirubin were absent, and echinenone and canthaxanthin were present at lower levels, interestingly, the upregulation of carotenoid biosynthesis led to an increase in the total carotenoid concentration (+31.4%) in leaves of the transgenic green plantlets.

This study examined the habitat status of wild birds at closed-trails and the control group of opened-trails in the national park of the Baekdudaegan mountains. After evaluating each area based on this, it's aimed at being utilized as basic data for future national park management and opening of trails. Upon field investigations and analyzing existing literary materials, it was found that there were a total of 76 bird species living around the trails. Among them, it was confirmed that 60 species can breeding and 10 species are protected by law. Upon assessing the scores of each area according to the evaluation standards of this study, Area I had 7 scores, area II had 13 scores, area III had 5 scores, and area IV had 16 scores, showing that the control group open-trail area IV between Jeongryeongchi and Seongsamjae had the highest score, and that area III of Wolyeongdae~Chotdaebong~Daeyasan~Miljae~Wolyeongdae had the lowest score. Evaluation of closed-trail according to wild bird species (Avifauna) was attempted in this study, but there were more bird species living in open-trails, while also having higher evaluation scores. Therefore, if opening trail is needed in the future due to excessive desires of visitors or inevitable social demands, it is judged that various environmental factors including mammals highly affected by people should be evaluated to open up the sector with the lowest score. Also, it is judged that through methods such as reservation systems, the number of visitors should be controlled or night-time hikes should be prohibited so that nocturnal wildlife can freely use the trails.

Avian paramyxovirus (APMV) type 4 and 6 were isolated during an avian influenza (AI) surveillance program of wild birds. This study also conducted experimental infection of wild-bird-origin APMV type 4 and 6 in specific pathogen free (SPF) chickens to study pathogenicity and transmission within domestic flocks. In addition, serological prevalence data of APMV type 4 and 6 in domestic fowls was conducted with chicken sera collected from 2007 to 2009 in order to understand infection status. The results of the animal experiment showed that APMV type 4 and 6 had the ability to infect chickens with sero-conversion and to transmit the virus from infected birds to contacted birds, but showed low pathogenicity. Serological tests revealed that APMV type 4 was widespread in the poultry industry, especially in layer flocks, but the positive rate for APMV type 6 was very low. This study concluded that wild bird-origin APMV type 4 and 6 could infect the chickens by inter-species transmission and the seroprevalence of APMV type 4 was quite high in Korean poultry. However, since almost all the chicken flocks had a high level of antibody titer against APMV type 1, there was possibility of cross reaction between APMV type 1 and 4, which made the interpretations more complicated. In order to understand infection status in the natural environment, additional study is necessary regarding the seroprevalence of APMV type 4 and 6 in the wild bird population.

Authors introduce a case of successful orthopedic surgery for humeral fracture of Common buzzard (Buteo buteo). The bird, juvenile male, was rescued due to illegal gun shot in Yeoncheon-Gun, Kyonggi-Do. The external skeletal fixation (ESF) with intramedullary pinning (Tie-in method) using Imex clamps was chosen for this fracture case. The common buzzard was anesthetized with hand made face mask and Isoflurane. In particular, the rescued bird was needed rehabilitating procedures, such as flight training or physical exercise for their survivals in wild habitats. The injured buzzard is successfully recovered without any damage to ligaments and nerves after 6 weeks.

To our knowledge, this is the first case of concurrent diaphyseal left coracoid and left femoral fractures in a Eurasian eagle owl and its post-release survival in Korea. The femur was surgically repaired using an external skeletal fixator-intramedullary (IM) pin tie-in method, and the coracoid was repaired solely with an IM pin on day 6 after femur surgery. The eagle owl underwent a gradual rehabilitation process. The bird was successfully rehabilitated and released 101 d after initial presentation. The bird was monitored using a wildlife tracking device and was confirmed to have survived for over 5 mon in the wild.

A filarial nematode was found in a blood sample of an Anas falcata individual collected in South Korea in 2018. Phylogenetic analysis based on partial cytochrome C oxidase subunit I (COI) sequences placed the nematode as a novel genus of the family Onchocercidae and as closely related to Mansonella species, Chandlerella quiscali, and filarial nematodes recently reported in avian species. However, different phylogenetic relationship was observed in the NADH dehydrogenase subunit 5 and 12S rRNA-based phylogenetic trees, which might indicate the filarial nematode found in this study was not defined to belong to the known specific genera of the family Onchocercidae. The screening of 105 additional avian blood samples retrieved only one 12S rRNA-targeting polymerase chain reaction (PCR)-positive sample, which indicates that filarial nematode infection is rare in wild birds or that it occurs below the detection limit of PCR in blood samples. Nevertheless, considering the recent findings about ancient interactions between birds and human pathogenic filarial nematodes and their pathogenic potential in several avian species, additional exploration of novel filarial nematodes in wild birds remains necessary.

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.
