[birding] Dusky Flycatcher? Silverton Marion County

[Matthew]

Hi Birders,

I believe I saw and heard a DUSKY FLYCATCHER in my yard this evening at 
8:30.  I heard a "whit" call coming from a tree outside my bedroom window. 
I went outside and briefly saw bird but it was just a backlit silhouette of 
a small bird (song sparrow size) that was flycatching.  Before I could get a 
good look at it the bird flew away.  The behavior instantly made me think of 
flycatchers and the whit call was very distinctive (Dusky Flycatcher is 
almost perfect match for what I heard).  Any ideas?
