Data Description:
The dataset includes RDS files (to be loaded in R) and one XLSX file. These contain information on acoustic measurements, specifically spectro-temporal and temporal structure characteristics of different components of rufous hornero (Furnarius rufus) duets: complete duets, overlapping duet sections, duet phrases, overlapping syllable parts, and non-overlapping syllable parts. Detailed information on the recording locations and settings is available in the referenced article.

Data Files:
pair_measures_list.RDS: Contains duet measurements at the pair level, divided into five vectors:
Spectro-temporal measurements of complete duets
Spectro-temporal measurements of overlapping duet sections
Temporal structure measurements of complete duets
Temporal structure measurements of overlapping duet sections
Spectro-temporal measurements of overlapping syllable parts

indiv_measures_list.RDS: Contains duet measurements at the individual level, divided into two vectors:
Temporal structure measurements of duet phrases
Spectro-temporal measurements of non-overlapping syllable parts
