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.

Eurasian eagle owl (Bubo bubo kiautschensis) is a natural monument (No. 324) and is also classified as an endangered wildlife grade II the Ministry of Environment of Korea. Eurasian eagle owl is threatened by the human being. But the efficient rescue and treatment for Eurasian eagle owl are still problematic, due to lack of basic data. In this study, to obtain basic resources for establishing more efficient rescue system, we held a physical examination and measured size physical part. In addition, we analyzed blood sample and feces samples and autopsy. We conduct the physical examination with measuring tapes and scales for 16 live features and 11 dead features. After inhalation anesthesia take the blood samples from wing vein. Blood samples are analyzed in hematologic and chemistric methods. We collected the feces through individual floor of cages from 12 live features and conducted the feces analysis. Autopsy was conducted for 11 dead samples. In physical examination, the mean body weight and total length of live features was 2.26${\pm}$0.35kg, 61${\pm}$2.38cm, the mean body weight and total length of dead features was 1.57${\pm}$0.51kg, 59.31${\pm}$3.51cm. Mean PCV was 46.57${\pm}$4.97%, while mean TPP was 3.49${\pm}$0.57g/dL. In feces sample analysis, 9 of 12 owls(75%) were infested by gastrointestinal helminths. The infection rates were: Trematoda (41.7%), Capilaria sp.(66.7%), acanthocephalans (25%). In autopsy, we confirmed 11 features were infested by duplicated infection of more than 2 helminths. Result of this study will be used for establishing reference range for physical features, blood analysis in Eurasian eagle owl. Therefore, to obtain basic resources for establishing more efficient rescue system, we have to make long-term conservation plans for Eurasian eagle owl.

본 증례는 야생 수리부엉이에서 혈액도말과 유전자 분석으로 무증상의 헤모프로테우스 감염을 확인한 것이다. 이것은 대한민국의 야생 수리부엉이에서의 헤모프로테우스 감염을 처음 보고한 것으로 야생 텃새들이 가금의 헤모프로테우스 감염원이 될 수 있음을 제시한다.

Wild owls are widespread in Korea, even being common in urban areas due to the presence of hills or small mountains in and around the cities. This results in high levels of contact between owls and domestic animals. This study investigated the prevalence of avian hematozoan parasite infection in 2 common owl species in Chungbuk province of Republic of Korea for 3-year period: the Eurasian eagle owl (Bubo bubo) and the Brown hawk owl (Ninox scutulata). Peripheral blood smears taken from 56 wild owls were examined by microscopic examination and confirmed by molecular technique. Twenty (36%) of these samples tested positive for the Haemoproteus infection. The infection rate was higher in Brown hawk owls (50%) than in Eurasian eagle owls (33%). These results indicate that the wild owls may act as a reservoir for Haemoproteus infection in susceptible domestic birds.

This study was conducted to determine genetic diversities of Eimeria spp. detected from wildlife. From January 2020 to December 2021, molecular analysis was conducted for Eimeria spp. detected from wildlife rescued in Jeonbuk province, Korea. Polymerase chain reaction targeting 18 s rRNA gene for Eimeria spp. detected from 8 domestic pigeon (Columba livia domestica), 1 Oriental turtle dove (Streptopelia orientalis), 1 Eurasian eagle owl (Bubo bubo), 1 Azure-winged magpie (Cyanopica cyanus), 1 Moorhen (Gallinula chloropus), and 1 raccoon dog (Nyctereutes procyonoides) was conducted for phylogenetic analysis. Domestic pigeon and Oriental turtle dove were bound to the same cluster. In addition, carnivorous Eurasian eagle owl and poultry were bound to the same cluster. These results suggest that Eimeria spp. can be shared between similar species regardless of species along the food chain, suggesting that wild birds could be carriers of Eimeria spp. in Korea.

본 연구는 2005년부터 2007년까지 파주, 강화도, 이천, 시화호, 충주 등 5개 지역에 서식하는 수리부엉이 9쌍의 둥지를 정기적으로 촬영, 관찰하여 번식생태와 교미행동을 연구하였다. 한배산란수는 $1\sim4$개로 평균 2.77개(n=15)였으며, 부화성공률은 약 71%(n=34)였고, 이소성공률은 약 83%(n=23)였다. 수리부엉이는 산란이 끝난 후에도 암수간의 교미행동이 지속되며, 새끼들이 둥지를 떠나는 시기인 부화 후 $7\sim8$주까지 교미행동을 계속한다는 것을 확인하였다. 이러한 수정 목적 이외의 교미 행동은 암컷과 수컷 모두의 필요에 의해서 이루어지는 것으로써 '부부관계(pair-bond)'의 확인, 유지, 강화를 통해 새끼를 안정적으로 키우기 위한 것으로 해석된다.

경기도 이천에서 3개의 알을 산란하여 포란 중인 수리부엉이 둥지를 촬영하였다. 2개의 알에서 새끼가 부화하였으나 1마리는 사라졌고, 2007년 3월 8일 남은 1마리가 사망한 후 어미는 죽은 새끼를 먹었으며, 이튿날 어미는 번식을 포기하고 둥지를 떠났다.

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.
