On the ledge of a strip mall roof,their pre-cut carrot stick legs stand,holding up football-shaped bodiesof white feathers.Separated by one wingspan from the next,their walnut-sized heads bob up and downwhile marble-colored eyes remain still.Without warning,one by one,they raise both wingslike Tesla Model X doors,leap into the void of spaceand ride the invisible hand of windhigh into the day’s blueness.
