But if you ask Mike Collins (aka "Fishcrow") the answer is a definitive NO.
http://fishcrow.com/Collins comes a bit out of left field and has had a lot of problems getting professional ornithologists to take him seriously, but he's doing some interesting things with flap rates and the physics of flight that to my admittedly math-challenged mind seem to be pretty darn good evidence for a large, non-pileated woodpecker in the Pearl River. For the life of me, I don't know why he relies on the digital camcorder and not a high megapixel digital camera with a big 500mm lens on it. Might have gotten the definitive picture if he did, since his camcorder stuff ends up with stuff that is less than indisputable.
