This collection comprises the log files that accompany the quality-controlled (QC) WBPHS-AK transcribed bird-observation data files. The log files were produced when the original (“raw”) transcribed data were run through the QC process via the “Greenlight” script within the R package “AKaerial” (available at github.com/USFWS/AKaerial). The log files describe any changes that were made to the raw transcribed data during the QC process. There is one log file for each QC transcribed data file: WBPHS_YYYY_QCLog_OOO.html, where YYYY=Year and OOO=Observer initials.
