In addition the decision was made not to split the White-breasted Nuthatch. A split that would have a significant impact on Oregon. I suspect the issue was not the conclusion that more than one species is involved, but the struggle to determine how many species (2 or 3 or 4). At the end of the supplement is a thorough discussion about each vote. It usually makes for interesting reading.

Both Michael Retter and Rick Wright have posted summaries of the changes on the American Birding Association blog site. Retter's summary is the second story down at the link below. In addition to the Sagebrush/Bell's Sparrow split, note the changes to shorebirds, with many species being shifted into the genus Calidris. Flammulated Owl gets assigned to a new genus, and Providence Petrel–a bird likely and perhaps already seen in Oregon waters–has been accepted and added to the North American list. I was happy to see the long-overdue abandonment of Little Shearwater has finally come about, with the records of small black-and-white shearwaters in the North Atlantic now more accurately reflected by the addition of Barolo Shearwater (replaces Little Shearwater on the AOU Checklist), which many sources (including Howell 2012) have been treating as a separate species. If I'm remembering this right (can't put my hands on our copy of Howell's book), mitochondrial DNA studies have shown that both Barolo Shearwater and Boyd's Shearwater (traditionally treated as Macronesian Shearwater) are more closely related to Audubon's Shearwater and not closely related to the nominate Southern Hemisphere Little Shearwater. http://blog.aba.org/ Dave IronsPortland, OR
