" Lodged in the stump and sticking straight up was a thin black feather about five or six inches long. To most it would have looked ordinary, maybe a crow's wing feather. But she knew it was extraordinary for it was the "eyebrow" of a great blue heron, the feather that bows gracefully above the eye, extending back beyond her elegant head. One of the most exquisite fragments of the coastal marsh, right here. She had never found one but knew instantly what it was, having squatted eye to eye with herons all her life.
A great blue heron is the color of gray mist reflecting in blue water. And like mist, she can fade into the backdrop, all of her disappearing except the concentric circles of her lock-and-load eyes. She is a patient, solitary hunter, standing alone as long as it takes to snatch her prey. Or, eyeing her catch, she will stride forward one slow step at a time, like a predacious bridesmaid. And yet, on rare occasions she hunts on the wing, darting and diving sharply, swordlike beak in the lead. "
