1 large dove - on telephone wires with Mourning Dove. The Mourning Dove looked pencil-thin compared to the unknown dove (UD). The UD was all gray at the chest, belly, throat, and sides of head. There was no buffy, or brown-ish to the bird. There were no visible black dots or white spots. When the bird flew, it was with wing beats of a Band- tail Pigeon; flat, snappy, wing beats. When the bird left its perch; the under tail showed a continuous, thick, white-gray terminal band. "Mexican Birds" by Peterson and Chalif - and NGS field guide showed no doves resembling the UD. I will try and get some photos.
