Have a part of your own bird story with the Carbonated Swamp-Warbler by John James Audubon. This hand-colored lithograph depicts two male warblers perched amidst the flowers of the “May-bush” (Serviceberry tree), and was published in the world-famous Birds of America under the number 60. There is a very special thing about this lithograph. The Carbonated Swamp-Warbler is considered to be one of the few mysteries created by John James Audubon himself – this is the bird that the great ornithologist says he killed in Kentucky in 1811, but it is still not found anywhere else.Is it an extinct wood-warbler? Maybe a rare hybrid? Or just a result of wrong memories after the destruction of his first sketches from rats?
