This repository contains a protocol to:
- download a subset of bird vocalizations from Xeno-Canto using R
- label birds' vocalization using Audacity
To download the files of recordings from Xeno-Canto (XC) from R run the R script: download_recordings_from_xc.R.
A detailed protocol is written in the protol.Rmd file.
After downloading the recordings from XC a separate CSV/XLSX file is created for each species. The columns of the files are:
- Recording_ID unique IDentifier for each recording assigned by XC
- birdlife_sci_name scientific name following BirdLife International's taxonomy
- English_name common name
- song_description_collins_bird_guide description of the song within the Collins bird guide
- jean_roche file name within the sound CD from Jean-Roche. Useful in case of taxonomy mismatches
- cd location of the CD file (CD are available on the google drive)
- Taxonomy information from XC: latin scientific name used in XC; Genus genus; Specific_epithet epithet; Subspecies subspecies
- Recordist name of the recordist
- Geographical information: Country; Locality; Latitude; Longitude; Altitude
- Vocalization_type Description of the vocalization from the recordist
- Audio_file https address of the file

- Url url address
- Quality "Recordings are rated by quality. Quality ratings range from A (highest quality) to E (lowest quality)." (see https://xeno-canto.org/help/search)
- Time, Date when was it recorded
- group in our case, the value is always birds
- sex sex of the individual
- stage Life stage of the individual
- method either field recording, capture in the hand, or unknown

- regnr "The regnr tag can be used to search for animals that were sound recorded before ending up in a (museum) collection. This tag also accepts a 'matches' operator" (see https://xeno-canto.org/help/search)
- auto Yes/No/unknown
- dvc; mic devices used
- smp "The smp tag can be used to search for recordings with a specific sampling rate (in Hz). For example, smp:">48000" will return hi-res recordings. Other frequencies include 22050, 44100 and multiples of 48000." (see https://xeno-canto.org/help/search)
