As If

Animals often mimic dangerous or toxic species to deter predators; however, mimicry of such species may not always be possible and mimicry of benign species seems unlikely to confer anti-predator benefits. We reveal a system in which a bird mimics the alarm calls of harmless species to fool a predator 40 times its size and protect its offspring against attack. Our experiments revealed that brown thornbills ( Acanthiza pusilla ) mimic a chorus of other species' aerial alarm calls, a cue of an Accipiter hawk in flight, when predators attack their nest. The absence of any flying predators in this context implies that these alarms convey deceptive information about the type of danger present. Experiments on the primary nest predators of thornbills, pied currawongs ( Strepera graculina ), revealed that the predators treat these alarms as if they themselves are threatened by flying hawks, either by scanning the sky for danger or fleeing, confirming a deceptive function. In turn, these distractions delay attack and provide thornbill nestlings with an opportunity to escape. This sophisticated defence strategy exploits the complex web of interactions among multiple species across several trophic levels, and in particular exploits a predator's ability to eavesdrop on and respond appropriately to heterospecific alarm calls. Our findings demonstrate that prey can fool predators by deceptively mimicking alarm calls of harmless species, suggesting that defensive mimicry could be more widespread because of indirect effects on predators within a web of eavesdropping.

Functional Explanations

AbstractThe results of a study of starling vocal mimicry are summarised and discussed in relation to various possible functional explanations of mimicry. Only one, a hypothesis based on sexual selection, is not rejected outright and even this was seen to have problems. A dif ferent approach yielded a causal hypothesis based on mistakes made during song learning. This causal hypothesis is consistent with all known features of starling mimicry, and can readily be extended to other species, but is probably not consistent with any of the candidate functional hypotheses, including the one based on sexual selection. It is tentatively concluded that there is no additional functional explanation of starling vocal mimicry.
