Clarence, I have been told that bird is a "Ring Necked Dove". I have never seen one, but heard them around town a lot the last couple of years. The sound is similar to a Mourning Dove, but with a different call.
They are a new bird here. I wonder where they came from. I have heard them here the past 3 years. This is the first year I have seen them in the open. There seems to be quite a number of them here now. Doves have several broods a year so they my increase fairly fast. I think the mourning dove only has 2 eggs to a brood, they don't make much of a nest either.
The Western bird book list the Ringed Turtle Dove as being arround Los Angles. The Eastern Bird Book says they are birds that have excaped from cages.
