红头黑铃鸽

红头黑铃鸽 is the rare Ogasawara bird discussed in 47.鸟有什么好看的：原来…丹顶鹤是秃的！. The episode says field counts in the early 2000s were extremely low, and it uses the species to show why protection work has to combine biology with social acceptance.

The conservation decision described in the source avoided simple killing of feral cats. Instead, local actors pursued capture, sterilization, and relocation or adoption, after which mountain feral cats largely disappeared from the area and the pigeon was seen more often. In the wiki, the species is a concrete case for Invasive Species Management and Conservation Intervention.
