摘　　要：2014年7月至8月,在天气良好的情况下,每天上午5:00至10:00时,利用TASCAM DR-680型录音机外接Sennheiser ME67话筒,录制了河北塞罕坝林场处于繁殖期的褐柳莺(Phylloscopus fuscatus)鸣声。录音的采样精度为16 bit,采样频率设置为44.1 k Hz。共获得41只个体清晰可供分析的录音,平均每只个体录到(47±16)句录音。利用Raven pro分析软件测量鸣唱参数,如每个句子和音节的最低频率、最高频率、起始频率及终止频率、持续时间和音节(音素)个数。进行统计分析后,发现河北地区褐柳莺鸣唱语句包含两种类型,句型较单一不变的S-song和句型多变的V-song。褐柳莺鸣唱句子的最高频率为(7.04±0.89)k Hz,最低频率为(1.75±0.30)k Hz,起始频率为(4.53±2.00)k Hz,终止频率(3.22±1.43)k Hz,句子的持续时间(1.24±0.32)s,由(6.50±1.91)个音节组成。基于语图上音节形态的差异,共发现49种不同的音节类型,每只个体鸣唱中使用2到30种音节类型。The dusky warbler（Phylloscopus fuscatus） is a summer migrant at Saihanba Forest Farm in Hebei Province,where it mainly inhabits in thin forests or thickets along the streams.During July to August 2014,we recorded dusky warbler songs between 5：00 a.m.and 10：00 a.m.within a distance of 10 meter in fine days in the breeding season.We used a TASCAM DR-680 recorder and a Sennheiser ME67 microphone with a Rycote Softie windshield to record the songs at a 44.1 k Hz sampling rate and 16-bit depth.Sonagrams were generated by Raven Pro sound analysis software.We got voices from 41 males,with an average of 47 ± 16 songs from each individual.Original measurements were taken to record the start and end time,start and end frequency,as well as the minimum and maximum frequency of each song.Count the numbers of the notes in the song by eye within Raven.For each syllable,the start and end time,start and end frequency,the minimum and maximum frequency were also measured.The measurements of the syllable were used for discriminant analysis to ensure the objectivity of syllable classification.We found the dusky warbler at Saihanba had two distinct kinds of songs,one was individually specific,stereotype song type（S-song）; the other was highly variable song type（V-song）（Fig.1）.The maximum and minimum song frequency were 7.04 ± 0.89 k Hz and 1.75 ± 0.30 k Hz,beginning and ending song frequency were 4.53 ± 2.00 k Hz and 3.22 ± 1.43 k Hz,with duration of songs being 1.24 ± 0.32 s and 6.50 ± 1.91 syllables in each song（Table 1）.Altogether 49 syllable types were found based on the structure in sonagrams of 41 males（Fig.2）,and 2 to 30 syllable types for each male.We analyzed the correlation of the number of syllable types with the number of songs from 10 males with most number of songs,and found the number of syllable types increased with more number of songs,and became stable when over 40 songs（Fig.3）.
