The Columbia jay. The jay is a native of Mexico rather than the Columbia river area in Oregon, and Audubon departed from an early resolve never to draw from a stuffed specimen Photograph: Christies Images Limited 2012The Carolina parrot. In Audubon's time the only species of parrot native to the US, it is now extinctPhotograph: Christies Images Limited 2012The mallard duck.

Although Audubon was careful to preserve lifelike poses for his birds – within the constraints of the printed page – he would prepare his specimens he had killed with fine shot. He would spend some four 15-hour days preparing the finished painting using wires to prop up the birds Photograph: Christies Images Limited 2012The American flamingo. Because it can stand up to five feet high, Audubon was obliged to depict the flamingo bending down, about to dip its beak into the waterPhotograph: Christies Images Limited 2012The snowy owl. Audubon developed his fascination with birds early in life, catching the enthusiasm from his father. 'I felt an intimacy with them … bordering on frenzy [that] must accompany my steps through life,' his biographer Richard Rhodes says Photograph: Christies Images Limited 2012This first edition of Birds of America by John James Audubon, originally bought by the Duke of Portland some time after 1828, is expected to become the world's most expensive book when it is auctioned at Christie's later this month.
