Note 158 — Chapter XII · EARLY DRAWINGS IN FRANCE AND AMERICA

Audubon said that some of the originals of The Birds of America were "made as long ago as 1805," which may well have been the case, but the earliest date which has been preserved on the drawings is that of July 1, 1808, for "Rathbone's Warbler," later recognized as an immature form of the Summer Warbler. The Carbonated Warbler was drawn May 7, 1811. Seven bear the date of 1812, namely: Yellow-rumped Warbler, April 22; Le petit Caporal, April 23; Wood Pewee, April 28; Blackburnian and Bay-breasted Warblers, May 12; Chestnut-sided Warbler, May 17; and Cuvier's Wren, June 8.
