Greetings All,
As the latest issue of the Auk (The AOU Journal) has yet to hit the streets, I 
got a private query about my "sources" for the latest AOU Checklist changes 
(54th Supplement). 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.
