Identifying the factors that determine the spatial distribution and habitat use of species of conservation importance is essential to developing effective conservation and management strategies. As seed dispersers, guans play a key role in the regeneration of forests in South America and are threatened mainly by habitat loss and hunting pressure. The Yungas Guan Penelope bridgesi, an endemic species restricted to the Southern Yungas of Argentina and Bolivia, has been recently recognized as a separate species. To determine the conservation status of Yungas Guan, information on its distribution and habitat use is urgently needed. The objectives of our work were to 1) determine the potential distribution of the Yungas Guan in the Southern Yungas of Argentina and 2) assess the influence of environmental and anthropogenic covariables on habitat use of the species. We used records of Yungas Guan to model the potential distribution of the species with MaxEnt software and developed occupancy models to determine habitat use and influential elements of the landscape (puestos, urban areas, roads, rivers, and elevation). We obtained data on the presence of Yungas Guan with camera traps, with an effort of 6,990 camera trap-days. The total potential distribution of the species was 21,256 km2. We found that the habitat use by Yungas Guan increased with proximity to rivers and streams. The probability of habitat use was 0.27, with a range of 0.02–0.42. Of the total potential distribution area, 15,781 km2 (81%) had a probability of habitat use greater than 0.2. This study is the first in determining the potential distribution of Yungas Guan in the Southern Yungas of Salta and Jujuy provinces in Argentina and highlights the importance of conducting analyses with occupancy models to assess the influence of environmental and anthropogenic variables and threats to cracid species.

确定决定保护重要性物种的空间分布和栖息地利用的因素对于制定有效的保护和管理战略至关重要。作为种子传播者，关在南美洲森林的再生中发挥着关键作用，主要受到栖息地丧失和狩猎压力的威胁。Yungas Guan Penelope bridgesi，一种仅限于阿根廷和玻利维亚南部永加斯的特有物种，最近已被确认为一个单独的物种。为了确定云嘎关的保护状况，迫切需要有关其分布和栖息地利用的信息。我们工作的目标是 1) 确定阿根廷南部永加斯地区永加斯关的潜在分布和 2) 评估环境和人为协变量对该物种栖息地利用的影响。我们使用 Yungas Guan 的记录通过 MaxEnt 软件对物种的潜在分布进行建模，并开发了占用模型来确定栖息地使用和景观的影响因素（puestos、市区、道路、河流和海拔）。我们使用相机陷阱获得了有关 Yungas Guan 存在的数据，努力了 6,990 个相机陷阱日。2 . 我们发现 Yungas Guan 的栖息地使用随着靠近河流和溪流而增加。栖息地利用概率为 0.27，范围为 0.02-0.42。在总潜在分布区域中，15,781 km 2 (81%) 的栖息地利用概率大于 0.2。这项研究首次确定了阿根廷萨尔塔省和胡胡伊省南部 Yungas Guan 的潜在分布，并强调了使用占用模型进行分析以评估环境和人为变量的影响以及对疯狂物种的威胁的重要性。
