Behavioural changes in aposematic Heliconius melpomene butterflies in response to their predatory bird calls
<p>Prey-predator interactions have resulted in the evolution of many anti-predatory traits. One of them is the ability of prey to listen to predators and avoid them. Although prey anti-predatory behavioural responses to predator auditory cues are well described in a wide range of taxa, studies on whether butterflies change their behaviours in response to their predatory calls are lacking. <em>Heliconius </em>butterflies are unpalatable and form Müllerian mimicry rings as morphological defence strategies against their avian predators. Like many other butterflies in the <em>Nymphalidae </em>family, some <em>Heliconius </em>butterflies possess auditory organs, which are hypothesized to assist with predator detection. Here we test whether <em>Heliconius melpomene </em>changes their behaviour in response to their predatory bird calls by observing the behaviour of male and female <em>H. m. plessini </em>exposed to calls of <em>Heliconius</em> avian predators: rufous-tailed jacamar, migratory Eastern kingbird, and resident tropical kingbird. We also exposed them to the calls of the toco toucan, a frugivorous bird as a control bird call, and an amplified greenhouse background noise as a noise control. We found that individuals<em> </em>changed their behaviour in response to Jacamar calls only. Males increased their walking and fluttering behaviour, while females did not change their behaviour during the playback of the jacamar call. Intersexual behaviours like courtship, copulation, and abdomen lifting did not change in response to bird calls. Our findings suggest that despite having primary predatory defences like toxicity and being in a mimicry ring, <em>H. m. plessini </em>butterflies changed their behaviour in response to predator calls. Furthermore, this response was predator-specific, as <em>H. m. plesseni</em> did not respond to either the Eastern kingbird or the tropic kingbird calls. This suggests that <em>Heliconius</em> butterflies may be able to differentiate predatory calls, and potentially the birds associated with those calls.</p>
