Observed two pair near the lower end of the tailwaters from Stagecoach Reservoir hawking bugs with several other birds.
This could also be a Pacific-slope Flycatcher as the two are very similar, but I used 'range' to make the call.
See 'previous' image for an UnCropped look at the bird's surroundings - very close to ground level.
Best viewed in 'original' size.
