''Rhea pennata'' was not always in the genus ''Rhea''. In 2008, the [[American Ornithological Society|SACC]], the last holdout, approved merging the genera ''Rhea'' and ''Pterocnemia'' on August 7, 2008. This merging of genera leaves only the genus ''Rhea''.<ref>{{cite web| url=http://www.museum.lsu.edu/~Remsen/SACCProproster.html | title=Classification of birds of South America Part 01 | access-date=4 February 2009 | last=Remsen Jr. | first=J.
