Widespread cultural change in declining populations of Amazon parrots

This dataset of parrot call measurements and metadata is associated with the article \"Widespread cultural change in declining populations of Amazon parrots\" in Proceedings of the Royal Society B. The data was used to address change and stability in regional vocal dialects of yellow-naped amazon (Amazona auropalliata) contact calls recorded in Costa Rica over three sampling periods that spanned 22 years., This data was primarily collected by acoustic recording, and was pre-processed for quality control. We have made detailed information about data collection and processing available in the data README as well as the accompanying mansucript., We primarily use the R software environment for analyses, and have made code to reproduce our analyses available on GitHub (see the link in the README)., This README.md file was generated on 01 June 2023 and updated on 15 July 2024 by Grace Smith-Vidaurre.
