Mean acoustic characteristics of vocalisations emitted by Lilac-crowned Amazons in eight behavioural contexts. (a) note duration, (b) low frequency, (c) high frequency, (d) bandwidth, (e) number of harmonics, all calculated from 58 note-types emitted ≥5 times across recordings. (f) emission rate was calculated considering all notes emitted in each behavioural context. Error bars show standard error. Significant from intercept: * P < 0.05, ** P < 0.01, *** P < 0.001. Forage was set as the baseline intercept in GLMM for all variables except note duration, which was set with the perched context
