西之岛 / Nishinoshima

Nishinoshima is the volcanic island case in 47.鸟有什么好看的：原来…丹顶鹤是秃的！. The episode says a 1973 eruption created new land that later merged with the old island, and that [[KawakamiKazuto|川上和人]] first landed there for research in 1995.

The island is used to make Island Ecological Succession tangible. Seabirds breed on the island, even using other birds’ bones as nesting material, but renewed eruption can bury old habitat and force researchers to watch from media, aerial images, or later surveys for signs of return.
