雄性tungara青蛙（Physalaemus pustulosits）产生复杂的呼叫，包括两个组成部分，一个类似于350毫秒的FM扫描称为“呜呜声”，其次是高达7个40毫秒的谐波爆发称为“卡盘”。为了选择和定位一个呼叫男性，女性参加合唱团必须分组呼叫组件到听觉流正确分配呼叫他们的来源。以前，我们表明，空间线索发挥有限的作用，在分组：呼吁与正常的频谱和时间结构的分组在广泛的角度分离（
Male tungara frogs (Physalaemus pustulosits) produce complex calls consisting of two components, a similar to 350 ms FM sweep called the "whine" followed by up to seven 40 ms harmonic bursts called "chucks". In order to choose and locate a calling male, females attending to choruses must group call components into auditory streams to correctly assign calls to their sources. Previously we showed that spatial cues play a limited role in grouping: calls with normal spectra and temporal structure are grouped over wide angular separations (
