Audubon experimented a long time before he hit upon a satisfactory method of drawing his birds. Early in his studies he merely drew them in outline. Then he practised using threads to raise the head, wing or tail of his specimen. Under David he had learned to draw the human figure from a manikin. It now occurred to him to make a manikin of a bird, using cork or wood, or wires for the purpose. But his bird manikin only excited the laughter and ridicule of his friends. Then he conceived the happy thought of setting up the body of the dead bird by the aid of wires, very much as a taxidermist mounts them. This plan worked well and enabled him to have his birds permanently before him in a characteristic attitude: "The bird fixed with wires on squares I studied as a lay figure before me, its nature previously known to me as far as habits went, and its general form having been perfectly observed."

His bird pictures reflect his own temperament, not to say his nationality; the birds are very demonstrative, even theatrical and melodramatic at times. In some cases this is all right, in others it is all wrong. Birds differ in this respect as much as people do--some are very quiet and sedate, others pose and gesticulate like a Frenchman. It would not be easy to exaggerate, for instance, the flashings and evolutions of the redstart when it arrives in May, or the acting and posing of the catbird, or the gesticulations of the yellow breasted chat, or the nervous and emphatic character of the large-billed water thrush, or the many pretty attitudes of the great Carolina wren; but to give the same dramatic character to the demure little song sparrow, or to the slow moving cuckoo, or to the pedestrian cowbird, or to the quiet Kentucky warbler, as Audubon has done, is to convey a wrong impression of these birds.
