Data and Song Files for "Global song divergence in barn swallows (Hirundo rustica): exploring the roles of genetic, geographic, and climatic distance in sympatry and allopatry"
All song files and measurements associated with MR Wilkins, et al. (2018) "Global song divergence in barn swallows (Hirundo rustica): exploring the roles of genetic, geographic, and climatic distance in sympatry and allopatry." Biological Journal of the Linnean Society.
Song Recording Descriptions:
We present 1700 recordings from 19 sites across 6 countries, encompassing 5 of 6 currently described barn swallow subspecies: rustica, erythrogaster, gutturalis, tytleri, and transitiva. We include the downsampled and filtered song files used for analysis in Avisoft. Some of these files have been edited slightly to erase loud sounds in the recordings which threw off measures of peak frequency (see methods). The original, unfiltered 48kHz recordings are also included in a separate ZIP archive.
Data File Descriptions:
1) Raw Song Measures_Wilkins et al_BJLS_2018.csv: Song measurements for each song file. Blanks are due to absence of a particular note (e.g. P-note) or inability to measure for a particular song (e.g. due to overlap with another bird).
2) Individual Mean Song Measures_Wilkins et al_BJLS_2018.csv: Average song measures for each individual.
