Aududon based his work on detailed studies of birds, both dead and alive in their natural habitats. He often portrayed them in motion, in contrast to his contemporaries. All birds were depicted life size. This is plate 72 from Audubon's famous work of natural history The Birds of America, which contained just over 700 North American birds.
