Abstract

Abstract Numerous species of long-distance, Nearctic–Neotropical migratory birds use Venezuela as a nonbreeding or migratory stopover site. We examined band recovery data (recaptures or dead-recoveries) in Venezuela from 1926 to 2017. The band recovery data included 1,891 individual birds, representing 42 species from 17 families. Banding countries or islands of origin included Argentina, French Guiana, Aruba, Barbuda, the United States (U.S.) Virgin Islands, Trinidad, the continental United States, and Canada. Blue-winged teal (Spatula discors; 1,432 of 1,891 total recoveries, 75.7%), royal tern (Thalasseus maximus; 117/1,891, 6.2%), osprey (Pandion haliaetus; 93/1,891, 4.9%), common tern (Sterna hirundo; 88/1,891, 4.7%), and bobolink (Dolichonyx oryzivorus; 27/1,891, 1.4%) were the most common banded birds in our assessment. Despite ongoing banding efforts, other bird species banded in Venezuela have not been recovered or recaptured in the Western Hemisphere. Despite significant social and political challenges that impede scientific research in Venezuela, the bird-banding community in Venezuela is growing, and this growth will likely facilitate our understanding of the annual cycle of numerous avifauna.

一个世纪以来委内瑞拉鸟类群落的恢复为迁徙生态学带来了深刻见解

摘要许多长途、近热带和新热带迁徙鸟类将委内瑞拉用作非繁殖或迁徙的避暑胜地。我们审查了1926年至2017年委内瑞拉的波段恢复数据（恢复或死亡恢复）。乐队的恢复数据包括1891只个体鸟类，代表17个家庭的42种。原籍国或岛屿包括阿根廷、法国-圭亚那、阿鲁巴、巴布达、美国（美国）。维尔京群岛、特立尼达、美国大陆和加拿大。蓝翅Teal（Spatula Discors；1891年总复苏中的1432只，75.7%）、皇家燕鸥（Thalasseus Maximus；117/1891，6.2%）、鱼鹰（Pandion Haliaetus；93/1891，4.9%）、普通燕鸥（Sterna Hirundo；88/1891，4.7%）和Bobolink（Dolichonyx Oryzivorus；27/1891，1.4%）是我们评估中最常见的带鸟。尽管正在进行强盗活动，但在西半球，在委内瑞拉被带到的其他鸟类物种尚未被发现或重新捕获。尽管存在重大的社会和政治挑战，阻碍了委内瑞拉的科学研究，但委内瑞拉的鸟带社区正在增长，这种增长可能有助于我们了解许多鸟类的年度周期。摘要许多新北极-新热带长途候鸟物种在非繁殖季节将委内瑞拉用作栖息地，或在迁徙过程中作为停留地。我们检查了1926-2017年委内瑞拉的环化数据（重新捕获或死亡重新捕获）。回收的环鸟数据包括42种17科1891只。标记的来源国或岛屿包括阿根廷、法属圭亚那、阿鲁巴、巴布达、美属维尔京群岛、特立尼达、美国大陆和加拿大。最常见的物种是Spatula discors（1891年中的1432种，75.7%）、Thalasseus Maximus（117/1891，6.2%）、Pandion Haliaetus（93/1891，4.9%）、Sterna Hirundo（88/1891，4.7%）和Dolichonyx Oryzivorus（27/1891，1.4%）。尽管努力继续环化，但委内瑞拉的其他环化鸟类物种在西半球尚未恢复。尽管委内瑞拉在进行科学研究方面面临着重大的社会和政治挑战，但该国的鸟类数量正在增加，这种增长可能会使我们更容易了解许多鸟类的年度周期。

期刊介绍： The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
