Changes to the sixth edition fall into six categories: <P>(1) 6 species are added to the main list because of new distributional information, including one transferred from Appendix A and three from Appendix B (Anser erythropus, Aerodramus vanikorensis = Collocalia bartschi, Machetornis rixosus, Motacilla citreola, Emberiza leucocephalos, and Carduelis spinus); <P>(2) 19 species are added to the main list because of the splitting of species previously on the list (Leptotila wellsi, Caprimulgus badius, Nyctibius jamaicensis, Anthracothorax veraguensis, Chlorostilbon auriceps, Chlorostilbon forficatus, Colaptes chrysoides, Contopus pallidus, Contopus hispaniolensis, Aphelocoma californica, Aphlecoma insularis, Catharus bicknelli, Saltator striatipectus, Pipilo maculatus, Ammodramus nelsoni, Icterus bullockii, Icterus abeillei, Hemignathus kauaiensis, and Hemignathus chloris); <P>(3) 3 species are changed by being split from an extralimital form (Pterodroma feae, Collocalia bartschii, and Piculus callopterus); <P>(4) 5 scientific names are changed because of generic reallocation (Ardea alba, Meleagris ocellata, Collocalia bartschii, Progne tapera, and Saltator grossus); <P>(5) a corrected spelling is provided for one specific name (Pluvialis dominicus); and <P>(6) 13 English names are changed, 10 of them to conform to the English names used in the sixth edition of the Checklist of Birds of Britain and Ireland (British Ornithologists' Union [BOU] 1992) for primarily Old World species that occur only accidentally or casually in North America. <P>Note that one species, formerly A erodramus vanikorensis now recognized as Collocalia bartschii, is affected by generic reallocation, a split from an extralimital species, moving from Appendix B to the main list, and a change in the English name. No distributional information except as it affects the status of a species on the list is included. The 25 additions to the list bring the number of species recognized as occurring within the Check-list area (main list) to 1,993. <P>Literature that provides the basis for the Committee's decisions is cited at the end of the Supplement. Literature that is necessarily included in the revised species accounts is cited in full within the account, in accord with the format of the sixth edition. <P><B>Links</B> <DL>   <DD><A HREF="http://www.nmt.edu/~john/z/nom/nomhome.html">Overview of systems for encoding bird names</A> </DL> </TD></TR> <TR> <TD VALIGN=top COLSPAN=2 WIDTH=600> <P><CENTER><FONT SIZE="-2">Questions or comments?<BR> Birding Related: </FONT><FONT SIZE="-2"><A HREF="mailto:ornithologist@birder.com">ornithologist@birder.com</A></FONT><FONT SIZE="-2"><BR> Advertising: </FONT><FONT SIZE="-2"><A HREF="mailto:sales@birder.com" onmouseover="window.status='mailto:jeff@birder.com'; return true">advertising@birder.com</A></FONT><FONT SIZE="-2"><BR> Technical: </FONT><FONT SIZE="-2"><A HREF="mailto:webmaster@birder.com">webmaster@birder.com</A></FONT> </CENTER> </TD></TR> </TABLE> </BODY>
