John James Audubon (1785-1851) lived a tumultuous life riddled with scandal and poverty but his prodigious effort to depict all of America’s birds at life size is today still widely heralded as the standard of wildlife illustration. The monumental Birds of America contains 435 plates depicting 1065 figures of 489 species of American birds, in life size, reproduced from Audubon’s paintings.
Audubon drew largely from specimens gathered in the field or from skins sent to him by naturalists to create his representations. To reproduce his paintings, the images were copied by means of etching on copper plates (often with additional aquatinting and, less frequently, with occasional engraving) and printed in black ink on “double elephant folio” paper by Robert Havell of London (except for plates I-X, which were editioned by W. H. Lizars of Edinburgh). Subsequent to printing, the images were hand colored with watercolor before being distributed, either in installments to subscribers (in eighty-seven parts of five prints each) or as complete bound copies to the general public.
Purple Finch
Purple Finch, Plate IV
From the beginning of November until April, flocks of the Purple Finch, consisting of from six to twenty individuals, are seen throughout the whole of Louisiana and the adjoining States. They fly compactly, with an undulating motion, similar to that of the Common Greenfinch of Europe.
