摘　　要：2010年春季在北京小龙门林场对灰眉岩鹀(Emberiza godlewskii)繁殖季的鸣唱进行了研究.共有24只个体录得清晰可供分析的录音,平均每个个体分析录音39句(最少14句,最多108句).结果表明:1)灰眉岩鹀鸣唱句子的最高频率为(9.73±0.41)kHz,最低频率(2.50±0.24)kHz,起始音素与下一音素的时间间隔为(0.26±0.06)s,句子持续时间为(2.32±0.42)s,由(14.33±1.93)个音素组成;2)灰眉岩鹀通过音素的重复、增减、替换来增加鸣唱的复杂性;3)不同个体间鸣声变量的差异性显著(P<0.05);4)有2只个体存在效鸣现象,对象分别为金翅雀(Carduelis sinica)和大山雀(Parus major).Song characteristics of Chestnut-lined Rock Bunting （Emberiza godlewskii ） is described. During the 2010 breeding season, song tracks from 24 territorial birds in Xiaolongmen forestry Beijing were analyzed, with an average of 39 song tracks from each individual bird. It was found that maximum song frequency was （9. 73 ±0. 41） kHz, minimum song frequency was （2. 50 ±0. 24） kHz. Duration between introductory and second notes was （0. 26±0.06）s, with a song duration of （2.32±0.42）s including 14.33± 1.93 notes.Individual birds increased the song diversity by repetition, addition, deletion, or substitution of notes. All song variables differed significantly among individual birds. Two individuals mimicked the song of Greenfinch （Carduelis sinica） and Great Tit （Parus major） respectively.
