SummaryThe Vietnam Pheasant Lophura edwardsi (including L. hatinhensis) is only known from a small area of central Vietnam, where it occurred in wet forest below 300 m. It is probably extinct in the wild, but some 1,500 birds, derived from 28 individuals caught in 1924–1930, survive in captivity. Guidelines for reintroducing galliforms date from 2009. Subsequent literature was reviewed for new research findings to help maximise the chances of success in reintroducing birds. Studies confirmed that non-parent-reared captive-bred galliforms survive poorly, primarily owing to inadequate anti-predator responses. These reflect both genetic and ontogenetic unsuitability to wild conditions, with progressive maladaptation of stock being related to the number of generations spent in captivity (at least 35 in the case of Vietnam Pheasant). To compensate as far as possible for this deficiency, a reintroduction programme should use: environmental enrichment (including the provision of perches in aviaries), dietary enrichment (especially involving practice with live food), parent-rearing over several generations (although how many are needed for a species almost a century in captivity is unknown), soft releases (allowing full familiarisation with the future environment over at least 50 days), rigorous anti-predator training (against both air and ground attacks), anti-predation release stratagems (relocating and deterring predators, releasing birds at several stations, offering post-release support), determining appropriate numbers (per batch, with at least 300 in total per site) and time-frame for release (around five years) and the selection of fully suitable releasees in (as far as possible) naturally formed social groups, including parent-guided offspring aged around four months. Six sites need survey for extant populations or use for reintroduction, and the choice of reintroduction site will depend primarily on habitat extent and condition. The costs of these measures will be high and the overall project schedule will need to extend beyond the overall five years currently planned.

为重新引入人工繁育的鸟类做准备：越南雉鸡 Lophura edwardsi 的案例

总结越南雉鸡爱德华七世（包含L.hatinhensis) 仅在越南中部的一小块地区已知，它发生在 300 m 以下的潮湿森林中。它可能在野外已经灭绝，但来自 1924 年至 1930 年捕获的 28 只个体的大约 1,500 只鸟类在圈养中存活。重新引入鸡形目动物的指南可追溯到 2009 年。随后的文献被审查以获取新的研究结果，以帮助最大限度地提高重新引入鸟类的成功机会。研究证实，非亲本饲养的圈养鸡形目动物生存不佳，主要是由于抗捕食者反应不足。这些反映了遗传和个体遗传不适合野生条件，种群的逐渐适应不良与圈养的世代数有关（越南雉鸡至少有 35 代）。为了尽可能弥补这一不足，包括四个月左右的父母指导的后代。六个地点需要调查现存种群或用于重新引入，重新引入地点的选择将主要取决于栖息地范围和条件。这些措施的成本将很高，整个项目的时间表将需要超出目前计划的五年。
