  • Fig. 1 Rates for T. cirrhosus to learn a familiar, unpalatable cane toad call from conspecifics compared to learning a novel acoustic prey cue under four treatments.

    Number of trials to learn from conspecifics to associate an unpalatable cane toad call with a palatable food reward (gray icon, far left) compared to number of trials to learn a 13-kHz pure-tone novel cue with food under four treatments (colored icons) (histograms display means ± SEM): (i) conspecific (conspecific model present), (ii) heterospecific (heterospecific model present), (iii) trial and error (naïve T. cirrhosus, no model), and (iv) social facilitation (naïve T. cirrhosus and naïve L. silvicolum, no model).
