Looked like a good candidate for Yellow-bellied Flycatcher, but perhaps not seen well enough to confirm in the field. Photos show a front view and seem to suggest Yellow-bellied Flycatcher pretty strongly, but may not be diagnostic—sometimes I'm surprised at how yellow other empids can look in the fall. I heard "whit" calls, consistent with Least or Willow, from low trees along the slope down from the Geddes entrance, then saw two Empidonax-like birds chasing each other around. The one that popped out and gave me the best views was this yellowish bird, with a greenish-yellow back and a moderately weak eye-ring. It looked like a dull Yellow-bellied to me, but I wondered if it could be an unusually yellow Least. As I continued trying to get better views, I saw this bird and an Eastern Wood-Pewee flycatching in the same tree, so those may have been the two flycatchers I saw earlier, leaving the source of the "whit" calls unexplained if this bird really was a Yellow-bellied. My naked-eye glimpse of this bird's back made me especially convinced it was Yellow-bellied, as its back appeared quite olive-yellow, in addition to its yellowish underparts. Addendum 26 Sep 2023: After doing a little more reading, I'm pretty confident this was Yellow-bellied. There must have been a second Empidonax, presumably Least but possibly Willow, giving "whit" calls here too, so I've updated my list accordingly.
