警报呼叫已解释从父母投资和巢防御的观点。呼叫应增加与育雏呼叫者的价值增加或与育雏的脆弱性增加。父母报警呼叫也可以从评估管理与呼叫者使用发声引起他人的情感反应，例如在沉默的后代。我研究了父母报警呼吁在塞浦路斯Wheatear（水芹cypriaca）在不同的发展阶段。塞浦路斯Wheatear会发出两种警报声，但其中一种仅在一年中的短时间内发出（II型警报声）。然而，普通的警报呼叫（I型警报呼叫）全年都在使用。捕食是由人类观察者使用一致的方法模拟的。育雏周期分为（I）孵化，（II）雏鸟，（III）早期羽化，（IV）晚期羽化。I型呼叫从I期到III期增加，之后减少。II型调用缺席孵化过程中，发生在雏鸟和早期羽翼未丰的阶段。作为结论，我认为，第一类报警电话可能是用来提醒配偶，阻止捕食者和信号强度的巢防御，而第二类报警电话是给后代。
Alarm calling has been interpreted from the viewpoint of parental investment and nest defence. Calling should increase with an increasing value of the brood to the caller or with increasing vulnerability of the brood. Parental alarm calling might also be viewed from assessment-management with callers using vocalisations to elicit affective responses in others, e.g. in silencing offspring. I examined parental alarm calling in the Cyprus Wheatear (Oenanthe cypriaca) at different developmental stages. The Cyprus Wheatear produces two alarm calls, but one is emitted only during a short period of the year (type II alarm call). The commoner alarm call (type I alarm call), however, is used year-round. Predation was simulated using consistent approach by human observers. The brood cycle was divided into (I) incubation, (II) nestling, (III) early fledging, and (IV) late fledging. Type I calls increased from phases I to III, and decreased afterwards. Type II calls were absent during incubating and occurred during nestling and early fledging stages. As a conclusion, I suggest that the type I alarm call might be used to alert the mate, deter the predator and signal strength of nest defence, while the type II alarm call is addressed to offspring.
