#' Pennsylvania Breeding Survey Data (BBS) from the USGS.
#'
#' A dataset containing Breeding Bird Survey (BBS) data collected by
#' the USGS since 1967.  Some columns have been removed to simplify the data.
#' See ftp://ftpext.usgs.gov/pub/er/md/laurel/BBS/DataFiles/Summary.txt for the
#' original metadata file.
#'
#' @format A data frame with 53940 rows and 10 variables:
#' \describe{
#'   \item{countrynum}{Numeric code indicating country.  USA = 840.}
#'   \item{statenum}{Numeric code indicating state.  PA = 72.}
#'   \item{Route}{numeric code indicating router number}
#'   \item{RPID}{Run Protocol Identification Number.  See RunProtocolID.txt file in USGS documentation}
#'   \item{Year}{Yeardata collected.}
#'   \item{Aou}{numeric species code from American Ornithological Union}
#'   \item{StopTotal}{Total number of stops out of 50 on which the species was recorded.  This is not a count of birds, but the number of stops that had a particular bird!  The min value is 1, and the max value is 50}
#'   \item{SpeciesTotal}{Total number of stops out of 50 on which the species was recorded.  This is what is usually used for modeling.  The min value is 1 because a given species in a given year only occurs in the data if it was observed; there are therefore no zeros.  These can be added using the expandBBS_routes() function.}
