audubon's dog goes birding

The great naturalist John James Audubon, of adventuresome spirit and tireless patience, speaks kindly here of aid given by his dog upon a heron-finding escape:
* * *
The young Herons seemed quite unconcerned when a person approached them, although on displaying one's hand to them, they at once endeavoured to strike it with their bill. My Newfoundland dog, a well-trained and most sagacious animal, was whistled for and came up; on which the birds rose partially on their legs, ruffled all their feathers, spread their wings, opened their bills, and clicked their mandibles in great anger, but without attempting to leave the nest. I ordered the dog to go near them, but not to hurt them. They waited until he went within striking distance, when the largest suddenly hit him with its bill, and hung to his nose. Plato, however, took it all in good part, and merely brought the bird towards me, when I seized it by the wings, which made it let go its hold. It walked off as proudly as any of its tribe, and I was delighted to find it possessed of so much courage.
