中文摘要：

采用人为观察法对内蒙古通辽市扎鲁特旗东北部区域内繁殖期栗斑腹鸡（Emberiza jankowskii）栖木与巢的距离及双亲是否对栖木重复利用进行了研究。结果表明：栗斑腹鸡在不同繁殖时期内．其栖木与巢的距离具有极显著差异（F=130．265，自由度为2，P≤0．001），产卵期为（21．90±5．06）m，孵化期为（16．80±5．10）m，育雏期为（7．80±3．85）m，且双亲均有重复利用同一栖木的习性，在育雏期栖木的重复利用最高。

英文摘要：

To find out the repeatability of perch selection in Emberiza jankowskii, we studied its perch choice and the perch dis- tance to nest during the breeding season in Zhalute Qi, northeast Inner Mongolia. The perch distance to nest significantly varied （F = 130.265, df= 2, P 〈 0.001 ） in different breeding stages, which was 21.90±5.06 m in egg-laying season, 16.80±5.10 m in incubation season, and 7.80±3.85 m in nesting season, respectively. The perch choice was repeatable in both parent Emberiza jankowskii and this repeatability was highest in the nesting period.
