• 一般注記: Differing quality and quantity of available resources among habitats, causes differentiation in mating signals. The acoustic environment is one such resource, and it can readily be divided by frequency (Hz). Among avian species that learn their calls, there are many examples showing that the characteristics of calls diverge in relation to the gradient or variance in the acoustic environment, such as the amplitude of environmental noise and sound attenuation, even among adjacent regions. In this study, we targeted a species that does not learn its calls, but inherits them. In such a species, adapting to the local acoustic environment may cause isolation among populations and eventually lead to speciation. Here we show that the differences between the acoustic environments of adjacent islands may cause pre-mating isolation in the Ruddy Kingfisher. We investigated differences in the characteristics of this migratory kingfisher’s innate calls among populations in the Ryukyu Archipelago. Their innate calls parallel their genetic structure. The kingfisher seems to avoid the loud environmental noise caused by cicadas. In addition, a playback experiment revealed that assortative mating might be occurring. Our results show that even nearby populations of birds that have flight capability may speciate due to acoustical adaptation.; (主査) 教授 髙木 昌興, 教授 増田 隆一, 准教授 江田 真毅（総合博物館）; 理学院（自然史科学専攻）
