摘　　要：Acoustic signals play an important role in animal communication systems,and these signals can transfer diverse and meaningful information from a signaler to a receiver(e.g.,Yu et al.2019).Animal signals tend to be honest;however,deception can occur when it is beneficial for receivers to send dishonest signals,such as by mimicking alarm calls to steal food from other individuals(Flower et al.2014).In birds,vocal mimicry is a widespread phenomenon that has 2 major functional explanation categories:intraspecific and interspecific communications(Dalziell et al.2015).Vocal mimicry in intraspecific communication mainly involves sexual selection and social affiliation(Dalziell et al.2015).In interspecific communication,studies on vocal mimicry are mostly related to predator–prey interactions(Dalziell et al.2015).Mimics could mimic calls of predators to scare off other predators or competitors.For example,some species of hole-nesting birds produce a snakelike hissing call to drive nest predators away(e.g.,Dutour et al.2020).Receiver should be particularly sensitive to the deceptive vocals of mimics if failing to respond to an actual model sound is costly.Therefore,the mimics could derive an advantage from mimicking the calls of predators of the receivers.A recent experimental study suggested that the bubbling calls of female common cuckoo Cuculus canorus mimic those of Eurasian sparrowhawk Accipiter nisus,and they primarily serve to distract regular hosts after laying eggs(York and Davies 2017).However,Xia et al.(2019)found that female cuckoo calls have other functions,including attracting mates and repelling rivals.
