Download eBird Trends Data Products — ebirdst_download

Download eBird Trends Data Products for set of species, or for an example species. Downloading Status and Trends data requires an access key, consult set_ebirdst_access_key() for instructions on how to obtain and store this key. The example data consist of the results for Yellow-bellied Sapsucker subset to Michigan and are much smaller than the full dataset, making these data quicker to download and process. The example data are accessible without an access key.

Usage

ebirdst_download_trends(
  species,
  path = ebirdst_data_dir(),
  force = FALSE,
  show_progress = TRUE
)

Arguments

species: character; one or more species given as scientific names, common names or six-letter species codes (e.g. "woothr"). The full list of valid species can be viewed in the ebirdst_runs data frame included in this package; species with trends estimates are indicated by the has_trends column. To access the example dataset, use "yebsap-example".
path: character; directory to download the data to. All downloaded files will be placed in a sub-directory of this directory named for the data version year, e.g. "2020" for the 2020 Status Data Products. Each species' data package will then appear in a directory named with the eBird species code. Defaults to a persistent data directory, which can be found by calling ebirdst_data_dir().
force: logical; if the data have already been downloaded, should a fresh copy be downloaded anyway.
show_progress: logical; whether to print download progress information.

Value

Character vector of paths to the folders containing the downloaded data packages for the given species. The trends data will be in the trends/ subdirectory.
