Abstract

Abstract This report documents the first direct evidence of inter-island dispersal of Ryukyu Scops Owl Otus elegans. Out of 134 individuals marked on Hateruma-jima Island in 2021, a female, which had been first captured as an adult bird, was discovered alive on Ishigaki-jima Island in 2022. The distance between the points of capture and resighting was 52.7 km. Since owls in the genus Otus show diversification between islands, direct evidence of movement between islands as given here, can contribute to future studies on the evolutionary process of the Otus owls.

琉球Scops Owl Otus elegans岛间传播的第一个直接证据

摘要本报告首次记录了琉球Scops Owl Otus elegans在岛屿间传播的直接证据。2021年，在Hateruma岛上标记的134只鸟中，有一只雌性鸟于2022年在石垣岛上被发现还活着，这只鸟最初是作为成年鸟捕获的。捕获点和重新定居点之间的距离为52.7公里。由于Otus属猫头鹰在岛屿之间表现出多样化，这里给出的岛屿之间运动的直接证据可以为未来研究Otus猫头鹰的进化过程做出贡献。
