摘要

摘要人们对勒孔特麻雀冬季分布的了解有限，特别是在墨西哥北部，那里被认为是稀缺的。在2016-2017年、2017-2018年连续冬季捕获2只勒孔特麻雀(Ammospiza leconteii)并绑扎;每个季节一个)在墨西哥科阿韦拉北部的山间草原上。这些记录距离该物种已知的越冬范围约300公里。两个地点的植被变化很大。第一个越冬地为低草盖度(18.7%)，主要为稻草属和布蒂卢瓦属;第二样地草盖度为72.6%，主要由布蒂洛瓦和Botriochloa组成。

Noteworthy Wintering Records and Habitat of LeConte's Sparrow (Ammospiza leconteii) in Grasslands of Coahuila, Northern Mexico

Abstract. There is limited knowledge on the winter distribution of LeConte's Sparrow, especially in northern Mexico where it is considered scarce and rare. We captured and banded two individuals of LeConte's Sparrow (Ammospiza leconteii) during consecutive winters (2016-2017, 2017-2018; one in each season) in an intermountain grassland of northern Coahuila, Mexico. These records were ca. 300 km outside the known wintering range of this species. Vegetation was variable at both sites. The first wintering site consisted of low grass cover (18.7%) dominated by Eragrostis and Bouteloua; the second site consisted of 72.6% grass cover, mainly composed of Bouteloua and Botriochloa.

期刊介绍： The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist have broadened and its geographic coverage now includes North America with occasional articles from other continents. The old image of naturalist has changed and the journal publishes what Charles Elton aptly termed "scientific natural history" including field and experimental biology. Its significance and breadth of coverage are evident in that the American Midland Naturalist is among the most frequently cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.
