eBird

eBird Observational Dataset (EOD) accessed though GBIF. The EOD contains basic occurrence data including species, date, and location. Additional metadata associated with these observations, including sampling event data (such as effort), are not included. Observer names have been anonymized.

eBird publishes a new version of the data usually once per year.
