SummaryAmazona lilacina is a threatened species endemic to Ecuador, existing across a patchwork of mangroves, lowland coastal forests, agricultural and community owned land. The species was described in 2014 and listed as ‘Endangered’ on the IUCN Red List, however, full assessment of the population was lacking. Using a combination of field observations, roost surveys and community questionnaires, conducted over the last 20 years, we provide up-to-date information on the species’ Extent of Occurrence, estimate its global population size, and evaluate its level of threat. Our results suggest the species occurs across an area of 19,890 km2 in three distinct geographically isolated subpopulations. Roost surveys across the range estimate the minimum remaining population at 741–1,090 individuals and we present evidence to suggest a 60% decline over the past 19 years in one part of the species’ range. We conducted community questionnaires with 427 people from 52 communities. The presence of pet parrots was reported in 37 communities, including 17 communities which reported pet A. lilacina. From this we predict that over half of all communities within our study area keep parrots as pets and at least 96 communities keep A. lilacina. Our findings justify an IUCN Red Listing of at least ‘Endangered’ for this species and highlight the need for conservation support. In order to assess population health in more detail, further research is required to assess genetic diversity and roost dynamics, and to identify areas that may be important for feeding and nesting throughout the range. As many of these areas are likely to overlap with community owned land, we suggest that future conservation actions should revolve around, and be led by, these communities.

最近描述的厄瓜多尔亚马逊鹦鹉Amazona lilacina的保护状况

概括紫丁香是厄瓜多尔特有的受威胁物种，分布在红树林、低地沿海森林、农业和社区拥有的土地上。该物种于 2014 年被描述并在 IUCN 红色名录中被列为“濒危”物种，但缺乏对种群的全面评估。我们结合过去 20 年来进行的实地观察、栖息地调查和社区问卷调查，提供有关该物种发生程度的最新信息，估计其全球种群规模，并评估其威胁程度。我们的研究结果表明，该物种分布在 19,890 平方公里的区域2在三个不同的地理上孤立的亚群中。整个范围内的栖息地调查估计最小剩余种群为 741-1,090 个人，我们提供的证据表明在过去 19 年中，该物种范围的一部分下降了 60%。我们对来自 52 个社区的 427 人进行了社区问卷调查。37个社区报告了宠物鹦鹉的存在，其中17个社区报告了宠物鹦鹉A.紫丁香。据此，我们预测，我们研究区域内超过一半的社区饲养鹦鹉作为宠物，至少有 96 个社区饲养A.紫丁香。我们的研究结果证明了 IUCN 红色名录至少对该物种“濒临灭绝”，并强调了保护支持的必要性。为了更详细地评估种群健康，需要进一步研究以评估遗传多样性和栖息动态，并确定可能对整个范围内的饲养和筑巢重要的区域。由于其中许多区域可能与社区拥有的土地重叠，我们建议未来的保护行动应围绕这些社区并由这些社区领导。
