Sibley

Someone finds a misidentification in the Sibley Guide:

Which leads me to another worry. It's plain that Mr. Sibley is a supreme incompetent; but could it also be that the ornithology establishment and birding public don't share my concern either? If they did, the outcry would be enough to inspire a revision. But so far, and to the best of my knowledge, there's been complete silence on the matter. Is there some kind of mass collusion going on here? Or is this Sibley's scheme to make his work more accessible—to make it just as factually deprived as its readers? The world is insane.
