我们使用 3 个物种的自由飞行蝙蝠的回放演示来评估回声定位呼叫设计和觅食策略对回声定位呼叫在交流中的作用的影响。靠近水面的进食地点，鼠耳蝠和鼠耳蝠。 yumanensis 仅对同种动物的回声定位呼叫做出积极反应。在栖息地附近，这些蝙蝠在当年的幼崽变得振翅之前没有做出反应，之后对类似和不同设计的回声定位呼叫做出反应。在喂食地点，北极拉西鲁斯只对同种动物的回声定位呼叫做出反应，尤其是“喂食嗡嗡声”。虽然鼠耳蝠，尤其是亚成虫，似乎利用同种动物的回声定位来定位进食地点，但鼠耳蝠。北极生物似乎利用觅食邻居攻击猎物时的叫声来识别“偷窃”食物的机会。
We used playback presentations to free‐flying bats of 3 species to assess the influence of echolocation call design and foraging strategy on the role of echolocation calls in communication. Near feeding sites over water,Myotis lucifugusandM. yumanensisresponded positively only to echolocation calls of conspecifics. Near roosts, these bats did not respond before young of the year became volant, and after this responded to presentations of echolocation calls of similar and dissimilar design. At feeding sitesLasiurus borealisresponded only to echolocation calls of conspecifics and particularly to “feeding buzzes”. WhileMyotis, particularly subadults, appear to use the echolocation calls of conspecifics to locate feeding sites,L. borealisappears to use the calls of a foraging neighbour attacking prey to identify opportunities for ‘stealing’ food.
