This is a pair of Mourning Doves. We seem to live in the midst of a covey (?) of them. They are all over the place. I sort of like them but then they don't perch right over my bedroom window. SWMBO says their mournful but monotonous call drives her crazy.
Incidentally, note the spelling. Some people refer to them as Morning Doves. Uh-uh. Not correct. I don't know why they seem so mournful but I have described them previously as one of the stupidest birds around. Maybe they know of their reputation and are expressing their unhappiness. Whatever it is . . here is a video of one "cooing."
Like I said, I kind of like them. But when you've heard that sad cry perhaps a couple of hundred times, it can get on the nerves.
