The eBird taxonomyis available for download. This update brings eBird up to date with Clements 6.7 (which will be released later this month), the most recent North American Classification Committee supplement (53rd supplement released in July 2012), and with South American Classification Committee decisions through June 2012.
These taxonomic updates involve three major elements. First, we must change the common name, scientific name, family, order, sort order, and several other elements everywhere that the name is used in our database. Second, we must add in a number of entirely new taxa, including newly described species, new hybrids that eBirders would like to report, or new groups that may someday become species.
