Update 4/27/12:
You can see this photo in a New Yorker article by Mary Norris about the Blackwing, though this blog isn’t cited. This picture is used for the Wikipedia article on the Blackwing, which has the text “blackwingpages” on it, but the blog name was removed and the photo darkened before the New Yorker published it. They credited Wikimedia Commons rather than this site, which is listed as the author of the photo.
