The file named "Parulidae_traitdata.xlsx" consists of five sheets:"trait_data": data for morphological, song and color traits of wood warbler species"trait_explanation": definitions of traits mentioned in the "trait_data" sheet"morpho_specimens": museum references of specimens used for morphological measurements"song_recordings": references of song recordings from two sources: Macaulay Library at the Cornell Lab of Ornithology (ML, URL: www.macaulaylibrary.org) and Xeno-canto (XC, URL: www.xeno-canto.org)"spectral_specimens": museum references of specimens used for spectrophotometric measurementsThe five sheets are also available in the repository as independent Microsoft Excel CSV tables, as "trait_data.csv"; "trait_explanation.csv"; "morpho_specimens.csv"; "song_recordings.csv" and "spectral_specimens.csv".The files were saved in Microsoft Excel Version 2305.

The file named "Parulidae_tempo-mode_code.txt" includes code and explanations necessary to replicate the analyses in the R software (R version 4.2.2; R Core Team 2022). This script is divided as follows:I. MODE OF EVOLUTIONII. DISPARITY THROUGH TIMEIII. RATES OF TRAIT EVOLUTION THROUGH TIME

The file named "myRPANDA.txt" contains code required to run before running the first part (I. MODE OF EVOLUTION) of the main script.

The file named "mcct.tree" contains the Maximum Clade Credibility tree constructed using the sample of trees from Barker et al. (2015) The Auk 132 (2): 333–48.

The file named "Barker100.txt" contains the hundred trees randomly selected from the sample of trees from Barker et al. (2015) The Auk 132 (2): 333–48.
