Dark-eyed Junco is about as far as my thoughts go. With so many variables, further classification is more frustration than I am interested in. Don't get me wrong, I love seeing interesting variations, I just don't have the brain space to sort out those variations.
I think what @IKLland is asking is, is there a Chihuahuan AND Eastern Meadowlark counted on the list or is there just one Meadowlark counted. I don't think I added a number to my Meadowlark so that may have messed up the count that is in questioned.
