小笠原群岛 / Ogasawara Islands
The Ogasawara Islands are the Tokyo-administered oceanic island setting in 47.鸟有什么好看的：原来…丹顶鹤是秃的！. The episode describes them as remote from Honshu and, apart from bats, lacking naturally distributed mammals, which makes them important bird habitat and a useful setting for thinking about island evolution, endemic species, and ecological disturbance.
In the source, the island branch includes 西之岛, 南硫磺岛, the 日本树莺 subspecies case, and protection work around 红头黑铃鸽. The islands connect local bird curiosity to Island Ecological Succession, Invasive Species Management, and Conservation Intervention.
