[wisb] "Audubon's" Warbler- Crawford County

Hey everyone, 
I found a winter "Audubon's" Yellow-rumped Warbler in Crawford County today 
while running my section of the Retreat CBC. 
This is the western subspecies of Yellow-rumped Warbler.  The International 
Ornithological Congress (IOC) considers this to be a separate species from 
"Myrtle's" Warbler (the eastern subspecies we always see here).  The AOU has a 
pending proposal to split the species as well (in which case the ABA would also 
split it). 
I don't know if the WSO keeps records of this subspecies or not, but it's 
probably a good idea to keep track of them in case they are ever split. If 
split, it's likely that the AOU would divide Yellow-rumped into three species. 
Myrtle's Warbler (eastern), Audubon's Warbler (western), and Goldman's Warbler 
(Mexico). Goldman's is by far my favorite. 

I had a total of 40 species on the Retreat CBC today including two adult Golden 
Eagles.  I'll post a summary of the count as soon as I have all the results in 
and tallied.

"The beauty and genius of a work of art may be reconceived, though its first 
material expression be destroyed; a vanished harmony may yet again inspire the 
composer; but when the last individual of a race of living things breathes no 
more, another heaven and another earth must pass before such a one can be 
again."

(From William Beebe's "The Bird: Its Form and Function," 1906)
