Howdy Tennessee e-Birders,

eBird has finally implemented the recent splits of Winter/Pacific/ 
Eurasian Wren and Eastern/Mexican Whip-poor-will.  In Tennessee all  
previous reports of Winter Wren have been reassigned to the new,  
narrower sense of Winter Wren (the eastern North American species),  
and all Whip-poor-wills have been assigned to Eastern Whip-poor- 
will.  These are the only forms that have been documented to occur in  
our region.  Those of you who have put in eBird data for other states  
might want to check your records for these species from the overlap  
zones, as they may have been placed in a "slash" form and no longer  
be counted as full species.  You yourself may not know which way  
these observations should sort out, in which case the "slash" form is  
the best option.  But if you do actually know which species you  
observed, you can change them manually and get the species back on  
your lists.  In short, the indeterminate zones are:

Winter Wren -- Rocky Mountain and Great Plains States, including  
Arizona and New Mexico.  Wintering birds in California have been  
converted to Pacific Wrens; Winter Wren does occur there at that  
season as a rarity, however.

Whip-poor-will -- Colorado (where rare) and wintering birds in  
Central America.
