| 中文摘要: |
| 1997、2002和2005年5~7月,在陕西省、四川省和甘肃省内共7个地区采集云南柳莺(Phylloscopus yunnanensis)的鸣声样本,并分析采自不同地区的共40只个体的鸣声。发现云南柳莺的鸣唱(song)和鸣叫(calls)在同一地区存在一定的差异。比较99段云南柳莺的鸣唱声,发现持续时间与间隔时间之间存在显著的负相关(Pearson,r=-0.276,P=0.006,n=99)。单因素方差分析表明,不同地区云南柳莺鸣唱的最高频率、最低频率和持续时间没有显著差异,而音节的间隔时间及音素数量均存在显著差异(P=0.006;P=0.000)。结果表明,不同海拔、地区之间个体鸣唱音节间隔时间与海拔成正相关(Pearson,r=0.425,P=0.03,n=26)。 |
| 英文摘要: |
| In the spring-summer of 1997,2002 and 2005,the vocalization of 40 birds of Chinese Leaf Warbler(Phylloscopus yunnanensis)was collected in Shaanxi,Sichuan and Gansu Provinces and analyzed.We found that both songs and calls varied between individuals in the same area.We failed to find any significant difference in the highest and lowest frequencies among the characteristics of the songs collected at Lianhuashan(Gansu),Taibaishan(Shaanxi)and Longxihongkou(Sichuan),however,the duration between syllables and number of notes showed significant differences.Birds living in forest at higher altitude presented territory songs with lower frequency. |
