许多领地鸣禽将歌唱作为一种互动的社交信号，以减少邻居间的攻击行为。交流理论预测，领地鸣禽可能会使用一系列信号来指示攻击动机的分级水平。这一理论在鸣雀中得到了支持，鸣雀是一种使用多种不同的基于鸣叫的信号（例如鸣叫类型匹配）来在反鸣互动期间升级或减弱攻击性的物种。然而，如果鸟类与竞争对手所唱的歌曲类型不同，它们就无法输入“匹配”，这就提出了它们如何发出攻击性信号的问题。我们提供了两种替代信号策略的证据，非共享邻居可以使用它们来传达攻击性动机。在第一种情况下，一只鸟可以通过唱出其曲目中最相似的歌曲来“相似性匹配”竞争对手的歌曲，即使它无法输入匹配。另一种解决方案是邻居同意按照惯例将特定的非相似类型对视为匹配。传统匹配可能是一种新的信号类别，领土邻居可以将其与类型和相似性匹配一起使用，以维持攻击性动机信号的全部内容。
Many territorial songbirds use singing as an interactive social signal to reduce inter-neighbor aggression. Communication theory predicts that territorial songbirds may use repertoires of signals to indicate graded levels of aggressive motivation. This theory is supported in song sparrows, a species that uses several different song-based signals such as song-type matching to escalate or de-escalate aggression during counter-singing interactions. However, birds cannot type match if they do not share the song type their rival is singing, raising the question of how they might signal aggression instead. We present evidence for two alternative signaling strategies that non-sharing neighbors could use to communicate aggressive motivation. In the first case, a bird may 'similarity match' a rival's song by singing the most similar song in his repertoire, even if he cannot type match. Another solution would be for neighbors to agree to treat specific pairs of non-similar types as matches by convention. The conventional match is potentially a new class of signal that territorial neighbors may use along with type and similarity matching to maintain a repertoire of aggressive motivation signals.
