Historical accounts documenting the presence of a species, despite several known spatial and temporal weaknesses, are useful to understand distribution patterns, to establish conservation baselines, and to develop effective conservation strategies. An article by Flueck et al. (2022), based on historical records, proposes to reinterpret the past distribution, population dynamics, and migratory behaviour of the huemul (Hippocamelus bisulcus), an endangered deer endemic of the southern Andes. Our analysis of the same historical data revealed a range of questionable interpretations of the sources. Because of this, we argue that the conservation strategies for huemul proposed by Flueck et al. (2022) may be counterproductive and even potentially harmful.

Wetlands are environments with a high diversity and global importance due to the ecosystem services they provide. In Chile, most wetlands are threatened, including their avifauna, especially the two southern hemisphere swans (Coscoroba coscoroba and Cygnus melancoryphus). Here, we made three years of monitoring of abundance of both species in the Petrel wetland. Our results show that the Petrel wetland is an important site for the conservation of South American swan populations, with an abundance average of 38.5 ± 18.8 individuals of C. coscoroba (peak of 60 ind.) and 11.6 ± 12.4 individuals of C. melancoryphus (peak of 40 ind.). These swan species avoid sites close to urban areas and show a preference for habitats distant from anthropogenic activities. The detection probability of swans was influenced by minimum and maximum temperature and wind speed. The vegetation aquatic and riverine are key variables to the abundance of these swans. Our large monitoring highlights the importance of Petrel wetland for the conservation of southern swans and provide value information about their abundance patterns and the population dynamics of C. coscoroba and C. melancoryphus. These data support the need to develop conservation and management plans for this wetland.

Janthina and Recluzia species are pleustonic snails that feed on cnidarians and can be easily differentiated by their shells, which are of a striking purple to violet-blue hue in Janthina, and whitish to brownish in Recluzia. In the southeastern Pacific off Chile, four of the five extant Janthina species and a single species of Recluzia have been recorded. In this work, we present new records for Janthina janthina (Linnaeus, 1758) for specimens collected at San Felix Island, in the Desventuradas Islands, and for Recluzia lutea (Bennet, 1840) for a specimen collected at Robinson Crusoe Island, in the Juan Fernandez Archipelago. These records fill a gap in the geographical distribution of J. janthina in the southeastern Pacific and extend the distribution of R. lutea in about 3000 km from its previous record at Easter Island, being the most easterly record for the species.

The Screaming Cowbird (Molothrus rufoaxillaris) is a brood-parasite specialized in parasitizing the Grayish Baywing (Agelaioides badius). Recently, it started to parasite a new host, the Austral Blackbird (Curaeus curaeus), which has driven the expansion of its range to central Chile. However, its actual and potential distribution and the natural history of this interaction are scarcely known. In this note, we describe the distribution, habitat use and phenology of the species in Chile. Additionally, we present data on feeding events of Screaming Cowbird fledglings by Austral Blackbirds. For doing so, we analyzed data from a citizen-science project using Maxent and Random Forest models. We found that the Screaming Cowbird is distributed mainly in urban and agricultural habitats, avoiding native shrublands and forests. The potential distribution is driven by the temperature and the Austral Blackbird distribution. This note confirms the relationship between both species of icterids and gives new insights into how new host-parasite interactions can drive the range expansion of brood parasitic birds.

The concomitant effects of environmental physical constraints associated with the availability and quality of food will finally affect the energy budget of wild animals. This study aimed to determine the effect of seasonality on water level, behavioural and nutritional status of Black-necked swans inhabit the Budi Lake, Chile. In winter and spring, the water level was recorded using a graduated rod and a time budget of 60 swans/hours was recorded from 8 am to 6 pm using binoculars and the focal method. In order to determine nutritional status a subset of 20 birds were captured and weight, length, wingspan, and tarsal length were measured. Also, blood sample was collected to determine cholesterol, triglycerides, and total proteins plasma concentrations. Budi Lakeâs water level increase in winter (111 ± 3 cm vs 54 ± 0.6 cm, P = 0.04). In addition, winter swan population increased significantly the time allocated to foraging at morning, and the proportion of effortful foraging behaviour (37/222 vs 14/185, P = 0.01), assigning less time to resting activities (7 ± 4 % vs 11 ± 2 %, P = 0.05) compared with spring population. Nutritional status was not compromised in swan populations in both seasons. In conclusion, behavioral adjustments allow Black-necked swan populations to maintain an adequate nutritional status despite the increase in water level during winter season.
与食物的可得性和质量有关的环境物理限制的附带影响最终将影响野生动物的能量收支。本研究旨在确定季节性对智利布迪湖黑颈天鹅水位、行为和营养状况的影响。在冬季和春季，用刻度杆记录水位，从早上8点到下午6点，用双筒望远镜和聚焦法记录60只天鹅/小时的时间预算。为了确定营养状况，捕获了20只鸟，测量了它们的体重、长度、翼展和跗骨长度。同时，采集血样测定胆固醇、甘油三酯和总蛋白的血浆浓度。布迪湖冬季水位升高(111 ±3 cm vs 54 ±0.6 cm, P = 0.04)。此外，与春季种群相比，冬季种群在早晨觅食的时间和费力觅食行为的比例(37/222比14/185,P = 0.01)显著增加，而休息活动的时间(7 ±4%比11 ±2%，P = 0.05)显著减少。在这两个季节，天鹅种群的营养状况没有受到损害。综上所述，尽管冬季水位上升，但行为调整使黑颈天鹅种群保持足够的营养状态。

American mink (Neovison vison) represents a threat to both biodiversity and economy in various regions of the world, including Patagonia. This invasive species has been successfully removed from many areas of Europe. In Chile and Argentina there have been only patchily distributed attempts of local control to date and large-scale removal has been considered unfeasible. We analyzed available scientific information, to determine best-fit strategies and improved methodologies that increase efficiency (capture per unit of effort) in American mink control. We reviewed published papers about programs that aimed at local control, functional or total eradication of minks in the Web of Science (WoS) database. Based on accessible information, the influence of some field variables on capture efficiency was determined through a General Lineal Model. From 1525 results in the WoS search, 51 papers refer to mink control action carried out in 28 areas of Europe and South America since 1992. Trapping has been the most used and efficient capture method. Short trapping periods that cover larger lineal distances per control program, and the use of attractants, specifically pheromones, have led to improved control efficiency. Chilean, Scottish and English experiences showed among the highest trapping efficiency values. We identify areas of research needed on mink ecology and behavior and trapping techniques that could improve trapping efficiency. A control program that incorporates the outcomes of this data assessment has the potential to improve feral mink removal. But further research is required to ensure that these efficiency measures result in cost-effective control in Patagonia.
美国水貂(Neovison vison)对包括巴塔哥尼亚在内的世界各地的生物多样性和经济构成威胁。这种入侵物种已被成功地从欧洲许多地区清除。在智利和阿根廷，迄今为止只有零星分布的地方控制尝试，大规模清除被认为是不可行的。我们分析了现有的科学信息，以确定最适合的策略和改进的方法，以提高美国水貂控制的效率(单位努力捕获量)。我们回顾了在Web of Science (WoS)数据库中发表的关于局部控制、功能性或完全根除水貂的项目的论文。基于可获得的信息，通过一般线性模型确定了一些场变量对捕获效率的影响。从WoS搜索的1525个结果中，51篇论文提到了自1992年以来在欧洲和南美洲28个地区开展的貂控制行动。诱捕一直是最常用和最有效的捕获方法。每个控制程序的捕获时间较短，覆盖较长的直线距离，并使用引诱剂，特别是信息素，从而提高了控制效率。智利、苏格兰和英国的经验表明捕集效率值最高。我们确定了在水貂生态、行为和诱捕技术方面需要研究的领域，这些领域可以提高诱捕效率。结合这些数据评估结果的控制程序有可能改善野生水貂的清除。但需要进一步的研究，以确保这些效率措施在巴塔哥尼亚产生具有成本效益的控制。
