Abstract:

This is the seventh Supplement since publication of the 7th edition of the Check-list of North American Birds (American Ornithologists' Union [AOU] 1998). It summarizes decisions made by the AOU's Committee on Classification and Nomenclature—North America between 1 January and 31 December 2006. The Committee has continued to operate in the manner outlined in the 42nd Supplement (AOU 2000). Changes in this Supplement fall into the following categories: (1) two species are added because of splits in species already on the list (Anser serrirostris, Buteogallus gundlachii); (2) three species are added (two transferred from the Appendix) because of new distributional information (Oceanodroma hornbyi, Mesophoyx intermedia, Falco vespertinus); (3) the name of one species is changed because of a split from an extralimital species (Larus michahellis); (4) three generic names are changed, one because of a merger of genera (Spizastur into Spizaetus), two because of a splitting of genera (Megaceryle from Ceryle); (5) one English name is changed because of a split of the species (Anser fabalis), and (6) one species is added to the Appendix (Threskiornis aethiopicus). Further, one family (Cathartidae) is removed from the Order Ciconiiformes and returned provisionally to the Order Falconiformes, its traditional placement before 1998, although its true phylogenetic position remains uncertain. The addition of five species to the main list (four of which are also added to the list of species known to occur in the United States) brings the total known to occur in the Check-list area to 2,046. Literature that provides the basis for the Committee's decisions is cited at the end of the Supplement, and citations not already in the Literature Cited of the 7th edition (with Supplements) become additions to it. An updated list of the bird species known from the AOU Check-list area may be found at <http: //www.AOU.org/checklist/index.php3>.
