Taxonomic proposals

The following documents are proposals submitted to avian classification committees to revise current taxonomic treatments. Each proposal is a synthesis of both published and novel data as it relates to taxonomy, especially species limits. Proposals are considered by two committees of the American Ornithological Society; the North American Classification Committee (NACC) and the South American Classification Committee (SACC). Results of each proposal, once publicly available, are listed after the citation.
