Hi, Paul -
Like many "southern" birds with populations east of the Great Plains and also
with populations in the southwest, Common Ground-Doves from the two areas tend
to look a little different (I am away from my references, so I cannot say how
many subspecies are involved). Other examples include Great-tailed Grackles
(Lousiana and Texas birds are a lot bigger than the ones in Arizona, southern
California, and Nevada), Painted Buntings, Cardinals (Southwestern ones are
bigger), Cassin's Sparrows, and Eastern Meadowlarks. Whenever we have vagrants
of species with these distributions some of us tend to wonder which populations
they came from. In this case, the suggestion has been made that this stray is
from the east, rather than from the southwest.
This is not very relevant to countability in this case, but is very interesting
to some of us who like to try to understand causes of vagrancy.

This provenance question is not one I would raise -- or even know about...
;-) I'd just be happy to see a Common Ground-Dove in Oregon.
For those of us in the hoi poloi, what does "eastern" and "western" mean in
this context?

That is interesting. It looked redder to me than the ones I see in Arizona.
