They are called mourning doves. I was kidding when I said morning because that's when they seem so activeI always thought they were mourning doves until a few years ago. I mostly see them in the morning, too. I have all kinds of birds that try to commit suicide when I'm driving...I'm constantly braking for them. Luckily our speed limit is 25 in the residential areas. I feel bad for the person behind me, trying to do 40, who decides to tailgate. We have quite a few of those.
