1960年，塞舌尔八哥仅剩12只，仅存活于弗雷盖特岛，该原生鸟类面临严重灭绝风险。据2016年研究论文《濒危塞舌尔八哥的历史、现状与趋势》记载，到2015年9月，种群数量已增至约280只，分布于塞舌尔群岛的五个岛屿。种群恢复不仅仅依靠清除捕食者。研究人员记录了一系列综合措施，包括入侵捕食者控制、栖息地恢复、补充喂食、安装巢箱以及将鸟类迁移至其他岛屿。
In 1960, only 12 Seychelles magpie-robins remained on Frégate Island, putting the native bird at serious risk of extinction. By September 2015, the population had grown to approximately 280 birds across five islands in the Seychelles, according to a 2016 research article, The History, Status and Trends of the Endangered Seychelles Magpie-Robin. The recovery involved more than removing predators. Researchers documented a combination of measures, including invasive predator control, habitat restoration, supplementary feeding, nest boxes, and the relocation of birds to other islands.
尽管这些干预措施帮助建立了额外种群，但各岛屿成效不一，凸显了持续监测和管理的必要性。鸟类濒临灭绝的过程塞舌尔八哥曾栖息于花岗岩塞舌尔群岛的多个岛屿。农业开发以及入侵物种（包括老鼠和猫）的引入导致其数量下降。到1960年，弗雷盖特岛成为该物种唯一的生存地。
Although these interventions helped establish additional populations, the results varied between islands, highlighting the need for continued monitoring and management. How the bird came close to extinctionThe Seychelles magpie-robin once inhabited several islands in the granitic Seychelles. Agricultural development and the introduction of invasive species, including rats and cats, contributed to its decline. By 1960, Frégate was the only island where the species survived.
数十年间种群数量岌岌可危。2016年研究的作者记录显示，1977年和1978年弗雷盖特岛上约有38至41只，但到1988-1990年数量跌至17至21只之间。正式恢复计划于1990年启动，由皇家鸟类保护协会资助，最初由国际鸟类保护委员会（现称“国际鸟盟”）协调。保护工作重点在于控制引入的捕食者、改善栖息地以及提供更多成功繁殖的机会。
Numbers remained precarious for decades. The 2016 study's authors recorded approximately 38 to 41 birds on Frégate in 1977 and 1978, but the population fell to between 17 and 21 by 1988-90. A formal recovery program began in 1990, funded by the Royal Society for the Protection of Birds and initially coordinated by the International Council for Bird Preservation, now known as BirdLife International. Conservation work focused on controlling introduced predators, improving habitat and providing more opportunities for successful breeding.
巢箱为辅助繁殖提供了另一途径。研究人员报告称，开放式巢箱的离巢成功率为44%，椰子树冠为28%，天然巢穴为38%。这些结果表明巢箱可提供有用的繁殖场所，但它们只是更广泛保护战略的一个组成部分。从一岛到五岛将鸟类迁移至其他岛屿降低了该物种对弗雷盖特岛的依赖，并帮助建立了额外的种群。根据2016年的一项研究，迁移工作分阶段进行：1994年迁往库赞岛，1995年迁往库辛岛，2002年迁往阿里德岛，2008年迁往德尼岛。随着这四个额外种群的建立，塞舌尔鹊鸲占据了五个岛屿。
Nest boxes offered another way to support reproduction. The researchers reported fledging success in 44% of open-fronted nest boxes, compared with 28% in coconut palm crowns and 38% in natural nests. These results suggested that nest boxes could provide useful breeding sites, although they were only one component of a broader conservation strategy. From one to five islandsRelocating birds to other islands reduced the species' dependence on Frégate and helped establish additional populations. According to the 2016 study, translocations took place in stages: Cousin in 1994, Cousine in 1995, Aride in 2002 and Denis in 2008. With these four additional populations, the Seychelles magpie-robin occupied five islands.
各新种群的结果各不相同。到2015年，库赞岛和库辛岛的种群数量相对稳定，而德尼岛的种群持续增长。然而，阿里德岛在其奠基种群引入十多年后，于2014年至2015年间经历了急剧下降。研究人员无法确定确切原因，但考虑了包括疾病、幼鸟补充率低、社会冲突和遗传问题在内的几种可能因素。这一下降说明了单靠迁移无法保证种群的长期稳定。
The outcomes differed across the new populations. By 2015, numbers on Cousin and Cousine were relatively stable, while the population on Denis continued to grow. Aride, however, experienced a sharp decline between 2014 and 2015, more than a decade after its founding population was introduced. The researchers could not establish a definitive explanation, but considered several possible factors, including disease, low recruitment of young birds, social conflict, and genetic issues. The decline illustrated why translocation alone could not guarantee a population's long-term stability.
更新的信息来自2025年在弗雷盖特岛进行的一项普查。保护更新报告《塞舌尔鹊鸲：2025年普查洞察》显示，该岛上有200多只鸟和54个被占领的领地。记录在案的鸟类中约有一半佩戴了脚环。这些数字仅适用于弗雷盖特岛，不应视为所有五个岛屿的更新总数。
More recent information comes from a 2025 census conducted on Frégate Island. The conservation update, Seychelles Magpie Robin: 2025 Census Insights, reported more than 200 birds and 54 occupied territories on the island. Approximately half of the recorded birds had leg rings. These figures apply to Frégate alone and should not be treated as an updated total for all five islands.
普查于2025年4月30日至7月11日进行。调查员使用地图、GPS设备和回放叫声来寻找鸟类，拍摄其脚环并记录活动轨迹。每个领地至少被访问四次，以提高计数的可靠性。报告还解释说，天气、一天中的时间以及领地间的移动都可能影响探测，这意味着调查条件会影响记录到的鸟类数量。
The census ran from April 30 to July 11, 2025. Surveyors used maps, GPS devices and playback calls to locate birds, photograph their leg rings and record their movements. Each territory was visited at least four times to improve the reliability of the count. The report also explained that weather, time of day and movement between territories could influence detection, meaning that survey conditions can affect the number of birds recorded.
塞舌尔鹊鸲的恢复反映了数十年的协同保护，而非单一干预措施的成果。
The Seychelles magpie-robin's recovery reflects decades of coordinated conservation rather than a single intervention.
其种群数量从1960年弗雷盖特岛上的12只增加到2015年分布在五个岛屿上的约280只，标志着一个重要里程碑。2025年的普查提供了弗雷盖特岛上种群数量的一个较新快照，而其他岛屿上不同的结果凸显了分别追踪每个种群以了解该物种整体状况的重要性。
Its increase from 12 birds on Frégate in 1960 to approximately 280 across five islands by 2015 marked a major milestone. The 2025 census provides a more recent snapshot of the population on Frégate, while the different outcomes on the other islands underscore the importance of tracking each population separately to understand the species' wider status.
