(a) Mean number of alarm calls made to each model type: female cuckoo finch, male cuckoo finch, female southern red bishop and male southern red bishop. (b) Time spent mobbing (within 50 cm) each model by at least one prinia during the 300 s trial. (c) Mean colour difference (measured in JNDs) of accepted and rejected experimental eggs following presentation of a female cuckoo finch, female bishop or male bishop. p-values for pairwise comparisons were obtained by varying the reference category in the models. Asterisks denote significant differences and whiskers show ranges.
