Dusky Flycatcher

Dusky Flycatcher

Yuba Pass summit

This bird gave the "whit" call; it was foraging low down in brush; also compare the tail (longer) and primary extension (somewhat shorter, though view here a bit obscured) with the Hammond's Flycatcher at . The difference in calls ("whit" vs. "peek") is generally thought the most reliable distinguishing feature between the two Empidonax flycatcher species that regularly summer at Yuba Pass
