Shows lower mandible
观察细节
Went around and around on this empid. Thanks group for the interesting discussion! I'm finally settling on DUFL. Field marks in favor of DUFL: short primary projection, long notched tail, wing bars, white loral, some photos show a rounded-looking head, slight eye ring but not as large and tear-dropped as a western flycatcher. Also consistent with DUFL: "whit" call (according to Sibley) (audio attached). One field mark that isn't perfectly consistent is the light-colored lower mandible, but Sibley says that *usually* (but not always) a mostly dark bill. So of all the field marks, no single species is a perfect fit and something has to give, this leaves the one "usually" field mark as the sacrifice. The "whit" call rules out Western and Hammond's. I don't think it was a Gray Flycatcher because the color was too dark above and too yellow below, and the photos don't show any white edges on the tail, and it didn't tail dip (only a little bit of nervous tail jerking at the 1st sighting, when it was calling, and no tail movement the other two sightings). And the long notched tail rules out Willow Flycatcher. So DUFL is where I ended up... Photos and audio attached. If I'm wrong please let me know and I'll correct this ID.
