Abstract

The Mountain Caracara (Phalcoboenus megalopterus) and White-throated Caracara (Phalcoboenus albogularis) are two sister species each with a limited distribution along the Andes from Ecuador to Tierra del Fuego. They occur in remote areas and are among the least known caracaras, and their diet has been little studied, particularly for the White-throated Caracara. We investigated the diet of these two caracaras by analyzing photographs provided by citizen scientists and obtained from the Macaulay Library (eBird) and iNaturalist platforms. We obtained 43 photographs for Mountain Caracara and 42 photographs for White-throated Caracara that could be used to identify food items. Photographs of the Mountain Caracara showed the species mainly feeding on carrion, often of domestic animals, followed by human foods and garbage. Photographs of the White-throated Caracara showed this species mainly feeding on carrion and garbage. However, we did find photographs of both caracaras feeding on wild species including camelids, rodents, birds, lizards, and some invertebrates. Further research should investigate possible effects of human-derived items in the diet of these caracaras, such as malnutrition due to consumption of inappropriate foods, and effects of ingestion of plastics and toxic substances.

利用公民科学数据调查山地豚鼠（Phalcoboenus megalopterus）和白喉豚鼠（Phalcoboenus albogularis）的饮食情况

山地狞猫（Phalcoboenus megalopterus）和白喉狞猫（Phalcoboenus albogularis）是两个姊妹物种，各自分布在从厄瓜多尔到火地岛的安第斯山脉上，数量有限。它们分布在偏远地区，是最不为人所知的狞鸟之一，对它们的饮食研究也很少，尤其是白喉狞鸟。我们通过分析公民科学家提供的、从麦考利图书馆（eBird）和 iNaturalist 平台获得的照片，调查了这两种狞鸟的食性。我们获得了 43 张山狞鸟的照片和 42 张白喉狞鸟的照片，这些照片可用于识别食物。山地狞鸟的照片显示，该物种主要以家畜的腐肉为食，其次是人类食物和垃圾。白喉孔雀的照片显示，该物种主要以腐肉和垃圾为食。不过，我们也发现了这两种狞獾捕食野生动物的照片，包括驼科动物、啮齿动物、鸟类、蜥蜴和一些无脊椎动物。进一步的研究应该调查这些狞獾的食物中来自人类的物品可能产生的影响，例如食用不适当的食物导致的营养不良，以及摄入塑料和有毒物质的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
