It's Fall Dowitcher time; Long-billed or Short-billed? Those who like this kind of thing can find more at http://www.pbase.com/tgrey/dowitchers07 .

My amateur take: this one could be LB. Appears to be no primary extension, looks to be barring on the side of the breast rather than spotting, and the scapulars look squared-off (see http://www.pbase.com/tgrey/image/83305333 for both barring and scapulars.)
