“…Indeed, there is plenty of evidence showing that signallers can reduce negative effects of acoustic masking by modifying their signal properties such as frequencies (Cunnington & Fahrig, ; Francis, Ortega, & Cruz, ; Patricelli & Blickley, ; Slabbekoorn & Peet, ) or amplitudes (i.e., the Lombard effects) (Halfwerk, Lea, Guerra, Page, & Ryan, ; Zollinger & Brumm, ). Moreover, recent studies have shown that prior experience with noise can be related to such modifiability in signallers (Gentry, Derryberry, Danner, Danner, & Luther, ; LaZerte et al., ). Although evidence of signaller responses to noise is quite common (Slabbekoorn, ), behavioural responses of signal receivers has received comparably very little attention (but see Kleist, Guralnick, Cruz, & Francis, ; Luther, Danner, Danner, Gentry, & Derryberry, ) and, to our knowledge, only one study has investigated behavioural plasticity in receivers in response to noise (Halfwerk, Bot, & Slabbekoorn, ).…”
