超声波蝙蝠回声定位的发现促使人们广泛寻找其他动物的生物声纳系统，其中包括两个鸟类群体。一种是南美洲的油鸟（Steatornis caripensis：Caprimulgiformes），是夜行性的，吃水果。另一个是来自印度太平洋的白天活动的食虫金丝燕（属Aerodramus和Collocalia：Apodidae）。鸟类回声定位仅限于人类可听到的较低频率，这意味着系统的分辨率比大多数蝙蝠和齿鲸的超声波（>20 kHz）生物声纳更差。因此，鸟类的回声定位一直被贴上粗糙或初级的标签。然而，回声定位在至少16种现存的鸟类中被发现，并在鸟类谱系中进化了几次。鸟类使用注射器产生宽带点击式生物声纳信号，使它们能够在黑暗的洞穴和隧道中筑巢，可能捕食压力较小。关于鸟类回声定位的几个细节，从信号设计到觅食期间是否使用回声定位的问题，一直存在分歧。鸟类回声定位是否像发声蝙蝠一样复杂还有待观察。鸟类的回声定位性能似乎是上级的盲人使用显着相似的信号。然而，到目前为止，在鸟类的听觉系统（从中耳到高级处理中心）中还没有发现明显的专门化。轻型记录设备和用于检查信号和重建飞行路径的定制软件的出现现在提供了更详细地研究鸟类回声定位行为并解决这些问题的可能性。
The discovery of ultrasonic bat echolocation prompted a wide search for other animal biosonar systems, which yielded, among few others, two avian groups. One, the South American Oilbird (Steatornis caripensis: Caprimulgiformes), is nocturnal and eats fruit. The other is a selection of diurnal, insect-eating swiftlets (species in the genera Aerodramus and Collocalia: Apodidae) from across the Indo-Pacific. Bird echolocation is restricted to lower frequencies audible to humans, implying a system of poorer resolution than the ultrasonic (>20 kHz) biosonar of most bats and toothed whales. As such, bird echolocation has been labeled crude or rudimentary. Yet, echolocation is found in at least 16 extant bird species and has evolved several times in avian lineages. Birds use their syringes to produce broadband click-type biosonar signals that allow them to nest in dark caves and tunnels, probably with less predation pressure. There are ongoing discrepancies about several details of bird echolocation, from signal design to the question about whether echolocation is used during foraging. It remains to be seen if bird echolocation is as sophisticated as that of tongue-clicking rousette bats. Bird echolocation performance appears to be superior to that of blind humans using signals of notable similarity. However, no apparent specializations have been found so far in the birds' auditory system (from middle ear to higher processing centers). The advent of light-weight recording equipment and custom software for examining signals and reconstructing flight paths now provides the potential to study the echolocation behavior of birds in more detail and resolve such issues.
