Corvus macrorhynchos is one example of species following the island rule. The southern Ryukyus population as a whole has a much smaller body size than the neighboring Taiwanese population. In this case study, I conducted morphological, ecological and genetic examinations on four island populations in the Southern Ryukyus and compared them with the putative ancestral population in Taiwan. Although the studied islands were located very close to each other, there were found remarkable differences in morphology, ecology and genetics. In the Southern Ryukyus, the most massively dwarfed was the population ecologically the most similar to the ancestral Taiwanese population.

大喙鸟是遵循岛屿法则的物种之一。整体而言，琉球南部的人口比邻近的台湾人口要小得多。虽然被研究的岛屿彼此相距很近，但在形态、生态和遗传学上却发现了显著的差异。在琉球南部，最矮小的是生态上与祖先台湾人口最相似的人口。
