当警报信号用于警告其他人存在威胁时，警报信号发送器的可靠性可能存在差异。一些信号发送器的激励阈值太低，会发出错误警报，如果潜在的警报接收者想要最大化能量增益，则应忽略这些信号发送器。我们将幼年理查森地松鼠暴露给可靠的信号员和不可靠的信号员，前者的警报声与捕食者模型的呈现相匹配，后者的警报声在没有潜在捕食者存在时播放。接听电话的人会歧视个别报警呼叫者，并降低对不可靠呼叫者的响应。因此，像灵长类动物一样，松鼠能够通过将个体的身份与其过去的表现联系起来来形成可靠性的概念。
Where alarm signals function to warn others of the presence of threat, variation is likely to exist in the reliability of alarm signalers. Some signalers, with too low a threshold of excitation, will issue false alarms and should be ignored if potential alarm recipients are to maximize energy gains. We exposed juvenile Richardson's ground squirrels to reliable signalers, whose alarm calls were paired with the presentation of a predator model, and unreliable signalers, whose alarm calls were played when no potential predator was present. Call recipients discriminated among individual alarm callers, and reduced responsiveness to callers that had been unreliable. Thus, like primates, squirrels are capable of forming a concept of reliability by associating an individual's identity with that individual's past performance.
