Abstract

ABSTRACT We report 5 cases of progressive graying on the Great-tailed Grackle (Quiscalus mexicanus) and 1 case of white feathers, most likely due to injury, from northeastern Mexico and southern Texas, USA. The cases we report showed different degrees of intensity. The causes of graying in bird feathers are not clear; we discuss possible causes and external factors associated with it and highlight the importance of documenting cases of pigmentary abnormalities. RESUMEN (Spanish) Reportamos 5 casos de encanecimiento progresivo en el zanate mayor (Quiscalus mexicanus) y un caso de plumas blancas, posiblemente por lesión, en el noreste de México y el sur de Texas, EE. UU. Los casos que reportamos muestran diferentes grados de intensidad. Las causas del encanecimiento de las plumas de las aves no están claras; discutimos las posibles causas y factores externos asociados con ella, y enfatizamos la importancia de documentar casos de anomalías pigmentarias. Palabras clave: aberraciones cromáticas, albinismo, canoso progresivo, leucismo.

墨西哥东北部和德克萨斯州南部大尾石斑鱼的色素异常

摘要我们报告了来自墨西哥东北部和美国德克萨斯州南部的5例大尾海雀（Quiscalus mexicanus）进行性放牧和1例白羽海雀，最可能是由于受伤。我们报告的病例显示出不同程度的强度。鸟类羽毛放牧的原因尚不清楚；我们讨论了可能的原因和与之相关的外部因素，并强调记录色素异常病例的重要性。摘要（西班牙语）我们在墨西哥东北部和美国德克萨斯州南部报告了5例大扎纳特（墨西哥奎斯卡卢斯）的渐进性白发病例和1例白羽病例，可能是由于受伤。我们报告的病例显示出不同程度的强度。鸟类羽毛变白的原因尚不清楚；我们讨论了可能的原因和与之相关的外部因素，并强调记录色素异常病例的重要性。关键词：色差，白化病，进行性白发，白血病。

期刊介绍： Aims & Scope For more than a century, the Wilson Ornithological Society has published a scholarly journal with form and content readily accessible to both professional and amateur ornithologists. The Wilson Journal of Ornithology is a quarterly publication consisting of major articles based on original studies of birds and short communications that describe observations of particular interest. Each issue also includes reviews of new books on birds and related subjects, as well as ornithological news. Through an endowment from the late George Miksch Sutton, each issue of the Journal includes a full color frontispiece. Each current volume consists of approximately 500 pages. The principal focus of the Journal is the study of living birds, their behavior, ecology, adaptive physiology and conservation. Although most articles originate from work conducted in the western hemisphere (a large portion of the research on Neotropical birds is published here), the geographic coverage of the journal is global. The Journal is internationally recognized as an important, major journal of ornithology. The Edwards Prize is given annually for the best major article published during the previous year. The Wilson Journal of Ornithology was formerly named the Wilson Bulletin.
