This delicate little Flycatcher was not met with anywhere a.s a summer 

 resident, but during its autumnal migration was found to be very common 

 on the East Humboldt Mountain.s. It inhabited exclusively the aspen- 

 gi-oves and copses of tall alders and willows in the higher" cafions, and 

 seemed to keep in the darkest and most secluded places. The only note 

 heard was a soft pit.
