Abstract

The Eurasian Eagle-Owl (Bubo bubo) shows reversed sexual size dimorphism. We aimed to evaluate morphological size differences between the sexes of the smallest eagle-owl subspecies (B. b. kiautschensis), for which little morphometric information is available, and to develop a discriminant function for sex using a minimum number of morphometric parameters. We compared nine morphological measurements of 41 genetically or anatomically sexed eagle-owls admitted to a Korean wildlife rescue center and used discriminant function analysis of 29 birds (17 female, 12 male) with complete measurement data of nine biometrics. We developed four equations using three measurements (total length, head length, and weight) that had 86–96% accuracy for sexing Korean Eagle-Owls. The subspecies-specific morphometric data and discriminant functions we developed can help fill the current knowledge gap regarding the morphological characteristics of this little-known subspecies, benefiting researchers, wildlife managers, and veterinarians who work with or study this apex predator in the Korean forest ecosystem.

欧亚鹰鸮（Bubo bubo kiautschensis）最小亚种的反向性别二形性和形态性别鉴定

欧亚鹰鸮（Bubo bubo）表现出相反的性别体型二形性。我们的目的是评估最小的鹰鸮亚种（B. b. kiautschensis）的性别之间的形态大小差异，并使用最少的形态测量参数建立性别判别函数。我们比较了韩国野生动物救护中心接收的 41 只经基因或解剖性别鉴定的鹰鸮的九种形态测量数据，并对 29 只（17 只雌性，12 只雄性）九种生物特征的完整测量数据进行了判别函数分析。我们利用三种测量数据（全长、头长和体重）建立了四个方程，这些方程对韩国鹰鸮性别鉴定的准确率为 86%-96%。我们开发的亚种特异性形态测量数据和判别函数有助于填补目前有关这一鲜为人知的亚种形态特征的知识空白，使研究人员、野生动物管理者和兽医受益匪浅。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
