| 摘 要： | 通过对短嘴金丝燕(Aerodramus brevirostris)的传统遮挡放飞实验和飞行行为的观察,研究短嘴金丝燕回声定位的机制,同时利用SONY MD录音并用Cool Edit2.1软件进行声波分析,证明了该物种是能利用回声定位的鸟类。该物种定位的声波主频较低,所以其定位能力没有蝙蝠(Chiroptera)那样精确,个体主要还是依靠视觉定位,只有在全黑的情况下才利用声音定位的。

| Abstract: | Himalayan swiftlet (Aerodramus brevirostris) echolocation was studied through the traditional way of hindering flying experiment and observing the action of navigation. Using the digit recorder SONY MD Z710 to record the sound and analyzing the sound wave by the software of Syntrillium Cool Edit 2.1. The results prove that this specie can use the sound wave to locate the place . This location-voice's frequency is very low. Therefore,the ability of location of this species is less exact than that of bat(Chiroptera).Thus this species mainly depends on the sight to locate the direction,while in the whole dark situation,it depends on the echolocation. |
