* Nomenclature and taxonomic affinities are based on Clements 6th Edition published 2007 with updates through December 2009 maintained by the Cornell Laboratory of Ornithology, which relies largely on the AOU and SACC nomenclature committees.
** Species not accepted by Clements, AOU, or SACC that we recognize based on the IOC, field observations along with geographical separation, consensus opinions of field guide authors, and other sources. These species are potential splits in future Clements updates.
