To me, this looks like the carved wing of an angel.  Combined with the soft coo of doves, they seem almost celestial.  It seems fitting that many years ago, when I saw a pair of doves toddling down the sidewalk, I realized they reminded me of a pair of nuns in full habit.  We have a duo  that lives somewhere in the trees around us, and they come to the fountain often.  One lands, with a flutter, and then the other appears.  As one bows its head to drink, the other keeps an eye out for danger.  Then they switch duties, with the first surveying the scene while the other drinks.  They’re very nervous birds and are quick to take flight, but when I hear them arrive at the fountain outside my kitchen window, I try to take the time to enjoy their delicate beauty.
