Aptenodytes penguins have a recognition call consisting of a series of repeated syllables. Play-back experiments were conducted to determine the respective importance of the temporal pattern of syllables and the syllable structure. Two hybrid signals were created by switching the temporal pattern of the familiar call (partner or parent) with that of an alien call, then played back to relevant partners. The hybrid signal with the familiar temporal pattern of syllables and an alien syllable structure induced no response of individual recognition, while the hybrid signal with an alien temporal pattern of syllables and the familiar syllable structure elicited some positive responses.
帝企鹅有一种识别叫声，由一系列重复的音节组成。进行了回放实验，以确定音节的时间模式和音节结构各自的重要性。通过将熟悉叫声（伴侣或父母）的时间模式与陌生叫声的时间模式进行切换，创建了两种混合信号，然后回放给相关的伴侣。具有熟悉音节时间模式和陌生音节结构的混合信号未引发个体识别反应，而具有陌生音节时间模式和熟悉音节结构的混合信号则引发了一些积极反应。
