"The portrait, when finished, was brought into the parlor, one day after dinner, to be shown to the family, that they might judge of the progress I had made. It was placed against a chair, while the macaw was in a distant part of the room, so that he did not immediately perceive the picture as he walked about the floor, but when he turned round and saw the features of his enemy, he quickly spread his wings, and in great fury ran to it, and stretched himself up to bite at the face. Finding, however, that it did not move, he then bit at the hand, but perceiving it to remain inanimate, he proceeded to examine the picture behind, and then, as if he had satisfied his curiosity, left it, and walked again to a distant part of the room, but whenever he turned about, and again saw the picture, he would, with the same action of rage, repeatedly attack it.
