UPDATE: (11/4/08) Thanks to KatDoc for catching my mistake! I'll have to admit, I'd never seen a white-winged dove before. And while I wondered why it looked different than the other mourning doves I'd seen (and found in my Texas Birds field guide), I went with the info I had and relied on the blue eye-ring to identify the photos. Looks like I now get to add White-winged Dove to my life list!
In the meantime, I've added below a picture of what I think is really a Mourning Dove — taken, coincidentally, at lunch today — followed by the relabeled original images.
