Lithography and hand-coloring by American artist John T. Bowen (1801-c.1856). Comes from Audubon's famous seven volume portfolio "The Birds of America", First Royal Octavo Edition (1840-1844), which consists of 500 hand-colored lithographs. Based on a composition painted in Florida in 1831 or 1832. "This beautiful and singular bird" was prized for its wings and tail feathers which were made into fans in St. Augustine. The roseate spoonbill is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo. To make 'The Birds of America' more affordable and widely available, in 1839 John James Audubon began the first octavo edition, a smaller version of the folio which was printed and hand-colored by J. T. Bowen in Philadelphia. Employing a new invention, the camera lucida, the images were reduced in size, rendered in intermediate drawings by John James Audubon and his son John Woodhouse, and then drawn onto lithographic stones. These miniatures exhibit a remarkable amount of attention to quality and detail, as well as a meticulous fidelity to the larger works. Some compositional changes were made in order to accommodate the smaller format. Like the Havell edition, John James Audubon’s first...

He was initially unsuccessful financially prior to the publication of his famous work “The Birds of America”, spending time in debtor’s prison, once stabbing a disgruntled investor in self-defense. However, his obsession with birds and art motivated him to persist in his goal of documenting every bird in America via his watercolor paintings and publishing his works for all to enjoy. Audubon's first illustrations were published in a large elephant folio size. Due to their expense they were purchased in rather small numbers by the wealthy. To reach a larger audience, Audubon, with the help of his sons and J. T. Bowen, published a smaller octavo sized lithograph version, which were much more affordable. With the success of his bird projects, Audubon then turned his attention to four-legged animals. He explored the Missouri River in 1843 sketching the four-legged animals he encountered in their natural setting. His expedition covered some of the same regions recently explored by Lewis and Clark, traveling from present day Alaska to Mexico. Audubon realized that this was an opportunity to document these animals in the still relatively pristine American wilderness, before man encroached on their environment. Between 1845 and 1848, Audubon and his sons John Woodhouse Audubon...
