The mourning dove usually spends more time on the ground than in the oak tree - this is a lot nicer setting. Like the way the blue sky enhances that blue ring around his eye - and those neat pink feet.
I think mourning doves are so beautiful! Your shot really shows this one's pretty details. Wonderful light and blue sky, too. We don't see many of these doves, but we see a few now and then. They are our earliest nesters. I occasionally find their white eggshells on the lawn.
