Magnolia Warbler (Setophaga magnolia) flight calls demonstrate individuality and variation by season and recording location

Flight calls are short vocalizations frequently associated with migratory behavior that may maintain group structure, signal individual identity, and facilitate intra- and interspecific communication. In this study, Magnolia Warbler (Setophaga magnolia) flight call characteristics varied significantly by season and recording location, but not age or sex, and an individual’s flight calls were significantly more similar to one another than to calls of other individuals. To determine if flight calls encode traits of the signaling individual during migration, we analyzed acoustic characteristics of the calls from the nocturnally migrating Magnolia Warbler. Specifically, we analyzed calls recorded from temporarily captured birds across the northeastern United States, including Appledore Island in Maine, Braddock Bay Bird Observatory in New York, and Powdermill Avian Research Center in Pennsylvania to quantify variation attributable to individual identity, sex, age, seasonality, and recording..., , , # Data for: Magnolia Warbler (*Setophaga magnolia*) flight calls demonstrate individuality and variation by season and recording location

This record contains tabular acoustic measurements made in Raven Pro, recording metadata, and all analysis code and output.

## Description of the data and file structure

The folder 1_prepare_measurements contains three subfolders:

* 0_inputs

* The metadata subfolder contains metadata for each recording used in the analysis.
* The selection_tables subfolder contains measurements made in [Raven Pro](https://www.birds.cornell.edu/ccb/raven-pro/) for each call analyzed.
* 1_code

* The R script 1_load_selection_tables.R uses data files in 0_inputs. It summarizes acoustic measurements, calculates derived measurements, and merges the measurements with recording metadata. It then outputs a compiled dataset in csv format: 2_outputs/selections_compiled.csv. 0_selection_table_functions.R is a helper script that is called by 1_load_...
