摘要
为探究喙形态和鸣声频率间的关系,2015年7月5日至8月10日的上午5:00至10:00,天气良好条件下(无风、无雨),对处于河北塞罕坝繁殖期的33只褐柳莺(Phylloscopus fuscatus)进行了研究.结果发现:嘴峰和嘴裂与句子最高频率、最低频率、最大频率和频宽之间均无相关性;嘴峰和颤音最低频率之间成负相关,但是和最高频率、最大频率和频宽之间却无相关性;嘴裂和颤音特征间均无相关性.研究结果表明:嘴峰可以提供颤音最低频率的相关信息,声道可以影响声音的特性.
To study the relationship between beak morphology and sound frequency,from 5 July to 10 August 2015,we recorded 33 dusky warbler(Phylloscopus fuscatus)songs between 5:00 a.m.and 10:00 a.m.in fine days(no wind,no rain)in the breeding season.The beak morphology parameters and the sound characteristics were measured.The results showed that:there was no relationship between high frequency,low frequency,max frequency and bandwidth of songs and culmen or beak gape;culmen was found to correlate negatively with low frequency of trill,however,there was no correlation between the culmen and high frequency,the max frequency or the bandwidth;beak gape was not significantly related to the trill traits.The results of this study demonstrate that culmen can provide information about the low frequency of trill,and vocal tract can affect the characteristics of sound.
