The Shiny Cowbird, Molothrus bonariensis Gmelin, 1789, is a brood parasite of hundreds of small-bodied birds that is native to South American lowlands. Within the last 100 years this species has been expanding its range throughout the Caribbean, towards North America, but has rarely been seen above 2,000 m asl.
Here, we present records of Shiny Cowbirds in Quito, a city located 2,800 m above sea level that harbors a bird community typical of the Andean valleys. We found two juvenile individuals parasitizing two different pairs of Rufous-collared Sparrow (Zonotrichia capensis Müller, 1776). This report constitutes an altitudinal range expansion of reproductive populations of ca. 500m, which may have beenprompted by anthropogenic disturbance.
辉拟鹂(Molothrus bonariensis Gmelin,1789)是一种寄生于数百种小型鸟类的巢寄生鸟类,原产于南美低地。在过去的100年里,该物种一直在向加勒比地区、北美洲扩展其分布范围,但在海拔2000米以上的地区很少见。
在此,我们展示了在基多发现辉拟鹂的记录,基多是一个海拔2800米的城市,拥有典型的安第斯山谷鸟类群落。我们发现两只幼鸟寄生于两对不同的棕领雀鹀(Zonotrichia capensis Müller,1776)。本报告记录了该繁殖种群海拔范围约500米的扩展,这可能是由人为干扰引起的。
