南硫磺岛 / Minami Ioto

Minami Ioto is the protected uninhabited island fieldwork case in 47.鸟有什么好看的：原来…丹顶鹤是秃的！. The episode describes the island as south of Ioto, steep, hard to land on, and restricted as a protected natural environment.

The 2007 survey story turns Ornithological Fieldwork into a logistical and ethical problem. Researchers trained for climbing, relied on divers and climbers to land and move safely, cleaned people and gear to avoid carrying seeds or alien organisms, and faced the pressure that research disturbance must produce meaningful knowledge.
