摘要
在吉林省集安市采到绯鼠耳蝠 (Myotisformosus)样本 5只 ,为吉林省蝙蝠科新记录。对其体型与头骨进行了测量。对回声定位声波进行了录制和分析 ,发现其回声定位声波为FM型 ,一次完整声波包括1～ 2个谐波 ,主频率 (5 4 5 4± 6 3 9)kHz,通过回声定位声波特征推测 ,绯鼠耳蝠在较简单的环境中捕食中等大小的昆虫。
Five Myotis formosus were caught at Ji'an,which is a new record of Vespertilionidae in Jilin Province.Skull and body size were measured,and echolocation signals of the bats were recorded and analyzed.Echolocation signals of the bats were FM,including 1-2 harmonics,and the dominant frequency was 54.54±6.39?kHz.The bats might prey on insects of median size according to the characteristics of echolocation signals.
