Swainson, a British naturalist and illustrator best known for the quality of his art and being the first of his contemporaries to use lithography. According to Cornell University our friend here, the Swainson's Hawk (Buteo swainsoni) was originally identified in 1872 by Mr. Swainson as a Common Buzzard (Buteo buteo) until five years later when French biologist Charles Lucien Bonaparte classified it as it's own species and named it after Swainson.
I've only seen a Swainson's Hawk one other time and it was so far away from that it was only through close examination of the photos I had taken of it that I was able to deduce an identification. So this was Marty Stouffer, Wild America moment!
