Loss of vocal culture and fitness costs in a critically endangered songbird

The dataset contains X files: "Recordings_summary.xlsx" = full details of each male regent honeyeater, where, when and how it was recorded, whether that male was observed and or recorded in multiple years, which analysis each male could be included in and which sound file(s) correspond to which male. We have withheld sensitive location data (lat,long) because (i) of the critically endangered population status of the species and (ii) it is not required to replicate the data analysis with the files available here. Specific location data is available from the corresponding author upon reasonable written request. "Recordings for manuscript analysis.zip" = .wav regent honeyeater song sound files used in the manuscript. "Repeat recordings.zip" = .wav regent honeyeater song sound files, including repeat files of some males where available, for use in modelling song repeatability. "Regent honeyeater song script.R" "paired1.csv" = for re-running GLM of pairing status of males by song type and cultural norm. "nested2.csv" = for re-running GLM of nesting status of paired males by song type and cultural norm. "fledged1.csv" = for re-running GLM of nest success of nesting males by song type and cultural norm. "complexity_conspecs_mahal.csv" = for calculating Mahalanobis distances for the Blue Mountains population. "mahala.paired.bmtn.csv" = for re-running logistic regression of pairing status of Blue Mountains males by Mahalanobis distance. "mahala.nested.bmtn.csv" = for re-running logistic regression of nesting status of paired Blue Mountains males by Mahalanobis distance. "conspecifics.csv" = for re-running Mann-Whitney U tests on conspecific density versus species-specific or interspecific songs in the wild population. "manualoc_output1.csv" = for specifying start and end timings of songs in sound files for analysis in warbleR. "regent_PCA_params3.csv" = for multivariate analysis of spectral components of regent honeyeater songs- checking cross-correlations, distributions, log-transformations etc. "complexitymetrics1.csv" = for GLMs of song complexity by song type. "manualoc_duplicates.csv" = for specifying start and end timings of repeat recordings for analysis in warbleR.
