The National Audubon Society website does not offer free photographs of doves but offers free illustrations of the birds that form part of John James Audubon's life-sized watercolor collection of North American birds. The doves featured are the blue-headed pigeon, the Carolina pigeon and the band-tailed pigeon.
Other birds in the collection are various larks, gulls, parrots, pelicans and ducks. Others include geese, warblers, jays, hawks and eagles. Printed between 1827 and 1838, the collection comprises 435 watercolors of birds as painted by Audubon in their natural habitat. The National Audubon Society offers these illustrations as free high resolution downloads.
Audubon was a French-American ornithologist who painted, described and cataloged the native birds in his book "Birds of America." There are 119 copies of the book known to exist, of which 11 are in private collections. A first edition copy sold for $11.5 million at a Sotheby's auction in 2010.
