摘要
利用偏相关分析方法,分析了雄性栗斑腹鹀的鸣声质量与繁殖投入的关系.结果表明:雄性鸣唱率与首枚卵产期呈显著负相关(Pearson偏相关分析:r=-0.421,df=27,P=0.023);句子长度与雏鸟数目呈显著正相关(Pearson偏相关分析:r=0.598,df=16,P=0.024).雄性递食率与鸣唱特征无显著相关性.说明雌性栗斑腹鹀可能根据雄性鸣唱率评价雄性个体质量和抚育后代的能力.
Attracting females is considered to be one of the main functions of bird song.Both the rate and complexity of male song are assumed to be reliable cues,that may be used by the female when choosing a mate.A statistically significant negative correlation was found between song rate and the date for the first egg laid in the clutch（Pearson partial correlation analysis：r=-0.421,df=27,P=0.023）as well a positive correlation between the length of the song strophes and the number of fledglings（Pearson partial correlation analysis：r=0.598,df=16,P=0.024）.But no statistically significant relation was found between any of the song parameters and the male＇s feeding rate.These results suggest that females might use male song rate to assess male quality and ability to participate in raising chicks.
