Table 1.

Likelihood of currawongs displaying any immediate response (scan, flee) versus no response to playback, using a biased-reduced binomial general linear model (brglm). Log-odds ratios > 0 indicate currawongs are more likely to immediately respond to the first-named treatment compared to the second. Bolded p-values indicate statistical significance.
