中文摘要	2009年在安西极旱荒漠国家级自然保护区对黑顶麻雀Passer ammodendri的巢址选择进行了研究。所发现的92个黑顶麻雀只营巢于沙枣Elaeagnus angusifolia上，巢位于营巢树树高的1/3处。分析表明，黑顶麻雀偏好在胸径较大且较高的树上营巢，以减少环境的影响，同时选择枝条数最多的位置，增加巢的稳定性和隐蔽性，减少被天敌捕食的机率。黑顶麻雀对巢址特征的选择是其对大风天气环境的适应和减小捕食压力的结果。
英文摘要	The nest-site selection of saxaul sparrow Passer ammodendri was studied in 2009 in Anxi extra-arid desert national nature reserve. The nests were merely built in Elaeagnus angusifolia L. and were located in the lower proportion of arbor (about 1/3). The principal component analysis (PCA) suggested that four main factors, which were height of nest tree, diameter at breast height, canopy density and stem diameter of nest, affected nest-site selection of saxaul sparrow. Analysis indicated that saxaul sparrow select a thick diameter at breast height and tall tree to nest for decreasing environmental influence. Meanwhile, they located where have more branches to increase the imperceptibility and stability of the nests, and to reduce the probability of predation. The selection of nests’ traits is the result that saxaul sparrows adopt to the windy weather and reduce the pressure on predation.
