Abstract
Oilbirds can navigate in total darkness by echolocation. The sound energy in their sonar cries is unevenly distributed over the range from about 1 to 15 kilohertz, with a dominant frequency range of 1.5 to 2.5 kilohertz. This corresponds to the most sensitive range of their hearing as determined by neurophysiological methods. Behavioral tests in their home cave indicate that the smallest object avoided by this is a disk 20 centimeters in diameter.
摘要
油鸱能在完全黑暗的环境中通过回声定位导航。它们发出的声呐叫声中的声能在大约1千赫兹到15千赫兹的范围内分布不均，主频范围为1.5千赫兹到2.5千赫兹。这与通过神经生理学方法确定的它们最敏感的听觉范围相对应。在它们栖息的洞穴中进行的行为测试表明，它们能避开的最小物体是直径20厘米的圆盘。
