I may have missed this, but one important field mark that I did not see mentioned is the color pattern on the lower mandible. The eBird list I saw had a very nice close up photo showing an almost completely pale lower mandible with perhaps a small dark tip. In my opinion this argues against either Hammond's or Dusky Flycatcher, which generally if not always have a pale yellowish or pinkish color restricted to the basal one-third or less, with the outer two-thirds of the bill being dark.
