A pivotal debate on biodiversity conservation is whether the scarce budgets must be invested in critically endangered taxa or in those with higher chances to survive due to larger population sizes. Addressing the fate of extremely bottlenecked taxa is an ideal way to test this idea, but empirical cases are surprisingly limited. The reintroduction of the extinct-in-the-wild Alagoas curassow (Pauxi mitu) by Brazilian scientists in September 2019 added to the two other known cases of survival to bottlenecks of only two or three individuals. We exploit the reasons why this species has survived, and we report how investments to rescue the Alagoas curassow resulted in the protection of many other taxa, suggesting that in the face of the dramatic number of extinctions expected for the Anthropocene, integration must prevail over a choice.

在极端瓶颈后恢复并通过易地管理挽救：来自 Alagoas curassow 的教训（Pauxi mitu [Linnaeus, 1766]; Aves、Galliformes、Cracidae）

关于生物多样性保护的一个关键辩论是，是否必须将稀缺的预算投资于极度濒危的类群，还是由于种群规模较大而具有更高生存机会的类群。解决极端瓶颈分类群的命运是测试这一想法的理想方法，但经验案例却出奇地有限。巴西科学家于 2019 年 9 月重新引入已灭绝的野外 Alagoas curassow (Pauxi mitu)，这增加了另外两个已知的生存案例，使只有两三个个体的生存成为瓶颈。我们探索了该物种幸存的原因，并报告了拯救 Alagoas curassow 的投资如何保护了许多其他类群，这表明面对人类世预期的大量灭绝，整合必须战胜选择。
