Abstract

bbsAssistant: An R package for downloading and handling data and information from the North American Breeding Bird Survey

Highlights

  • This package was created to allow the user to bulk-download the Breeding Bird Survey (BBS) point count and related via file transfer protocol (FTP), and to quickly subset the data by taxonomic classifications and/or geographical locations

  • The primary audience is for those wishing to use BBS data in Program R for visualization or analysis, this package can be used to quickly download the BBS data to file for use elsewhere

  • Given the variability in data availability, the BBS team provides data credibility scores for species-regions combinations. This package contains the most recent results associated with these analyses as data objects, and provides a function (get_credibility_trends()) for retrieving all analysis results which are public-facing

Summary

Summary

This R package contains functions for downloading and munging data from the U.S Geological Survey’s North American Breeding Bird Survey (BBS) via file transfer protocol (FTP) This package was created to allow the user to bulk-download the BBS point count and related (e.g., route-level conditions) via FTP, and to quickly subset the data by taxonomic classifications and/or geographical locations. This package maintains data containing the trend and annual indices from the most recent (1996-2017) hierarchical population analyses The BBS provides a public interface for retrieving data and analysis results via FTP, bbsAssistant expedites the efforts of downloading, decompressing, importing, and subsetting the state/region-level point-count files, and other associated files (e.g., taxonomic information, geographic information, route-level conditions, geographical information). The primary audience is for those wishing to use BBS data in Program R for visualization or analysis, this package can be used to quickly download the BBS data to file for use elsewhere
