I hadn't, until you mentioned it. ;)
Mourning doves like to roost in the big tree outside our bedroom window, so we get to hear that call all the time!
I love to hear them in the woods behind our house in the morning. Sometimes a pair will fly down to our deck and sit on the railing and coo away! In the winter, they'll fly down to the deck and nibble at the seed below the bird feeder that the other birds have knocked down there. They are such an interesting color. One is 'Dove Gray' but there is one that is a soft rosy brown color that is lovely!
