Two species of forest birds, the least flycatcher and the red-eyed vireo, when breeding in the same season in the same habitat, adjust their temporal pattern of singing to avoid the overlapping of songs. The avoidance of acoustic interference is more marked in the flycatcher, which has a briefer song than the vireo.
两种森林鸟类，即最小的食虫鸟和红眼睛的绿鹃，当在同一季节、同一栖息地繁殖时，会调整它们的鸣叫时间模式，以避免歌声重叠。在食虫鸟中，这种避免声学干扰的现象更为明显，因为食虫鸟的歌声比绿鹃的歌声更短。
