I am about 80% sure this is a short-billed dowitcher, several folks on the FM Nature & Wildlife forum were able to help me out. I took this at the Palo Alto Baylands a while ago and finally had a chance to process it. These guys don't stand still, especially when feeding. I believe this one stood still for only a fraction of a second before resuming feeding.
