Females preferred conspecific song to heterospecific song
The first Bayesian model (Fig. 1 ) confirmed that females show a preference for conspecific song in the operant chambers. Population preference for conspecific song was 0.705 (95% credible intervals: 0.687, 0.748) and population preference for heterospecific song was 0.295 (95% credible intervals: 0.252, 0.313). Effective sample size (ESS), a measure of the MCMC chain function and not associated with sample size in a typical non-parametric analysis, was 1593.247. Average hops per conspecific/heterospecific trial was 521.93 (s.d. = 300.96). Full results from the conspecific/heterospecific preference trials can be found in the Supplementary Materials.
