## Summary

  The data are audio .wav files of birdsong motifs from young, middle-age and old adult male zebra finches.
  These wav files were analyzed in the above mentioned citation.

  Each individual .wav file is a motif, a basic of unit of birdsong that contains repeated elements
  known as syllables. The audio file can be played in Windows Media Player or opened in freeware
  programs (e.g., Audacity, Praat) to view as a wave form or spectrogram.

## Files and Folders

### Naming convention:
  Individual audio files have the naming convention based on leg band/color:  
   Bk-Black, Wh-White, R or Rd-Red, P or PR-Purple, Turq2-Turquoise, Or-Orange

  There are about 25 audio files per bird. 'M1' stands for Motif with the hyphen indicating the
  motif number (1-25' M1_1 to M1_25) and date of file is the original date recorded or processed.


### Files:
 
 - "Motif Example Bk262_May_2016_29378075_M1_1.wav": Example .wav file provided for Figshare preview
 - "Screenshot of Motif from Audacity.jpg": Illustration of spectrogram viewed from Audacity (see below)

 Individual audio files are included in three .zip files, separated by their age:

#### Young Adult song: 

Young Adults (Y) identifiers:
  Bk295
  Wh211
  Wh206
  Bk268
  Bk286
  Bk262
  Bk277
  R376


#### Middle Adult song:

Middle Age Adults (M) identifiers:
  Wh35
  R1156
  R1157
  Rd419
  Rd422
  Bk387
  Wh298
  Wh306

#### Old Adult song:

## Materials & Methods

The audio files can be played in any of these three programs and likely others. 
 - Windows Media Player: One can listen to audio
 - Audacity: https://www.audacityteam.org/. One can listen to audio and view it as spectrogram.
 - Praat: http://www.fon.hum.uva.nl/praat/ . One can listen to audio and view it as a spectrogram.
   Data were originally analyzed in this program for the publication and then exported.
