Alt text: Acoustic components of duets ranked above a threshold (dashed line), indicating their effectiveness in coding information about the identity of populations, pairs, sexes, and individuals in rufous horneros. Descriptions of these acoustic components can be found in Tables 2–3.

The potential of several spectro-temporal measurements and temporal structure of syllables of rufous hornero duets for discrimination of populations, pairs, sexes, and individuals of each sex, according with Potential of Identity Coding (PIC) values. In this study, we assume that values higher than 1 (indicated by dashed lines) might facilitate discrimination (Hahn et al. 2013). The acoustics measurements with the 10 highest PIC values for each class are shown as acronyms. For detailed descriptions of acoustic measurements and PIC values, refer to Tables 2–3.
