Morbidity of Rescued Wild Birds by Admission Causes in the Republic of Korea

Insufficient reports are available on what clinical and pathological conditions are observed in rescued free-living wild birds. This study investigated recent diagnoses of admitted wild birds based on admission causes in a southwestern area of South Korea over the past 2 years. A retrospective study was conducted on 1464 birds rescued from 2019 to February 2021. Overall, 12 admission subcategories were classified, and the diagnoses identified for each cause were analyzed. The three most frequently observed categories, general, integumentary, and musculoskeletal, each accounted for 20% of the total diagnoses. Trauma accounted for 71.4% of all diagnoses, and 81.5% featured inflammatory conditions, primarily due to trauma or infection. The proportion of birds that presented inflammatory conditions was much greater than the proportion of birds that were admitted due to trauma-related causes. This was because inflammatory diseases were identified at a high frequency, even from nontraumatic admission causes, and inflammatory conditions were not easily revealed. Suspecting an inflammatory condition in most rescued birds is advisable.
