Forwarding from Darren Clark on Facebook, Great Crested Flycatcher
confirmed at Camas NWR (1st state record):

“Hilary Turner

notified
me yesterday that she found a Myiarchus Flycatcher at Camas NWR (Jefferson
County). She had a very brief look and didn’t get enough of a look to
identify it. I went out this morning and located the bird and it was a bit
more accommodating. Turns out it’s a Great Crested Flycatcher (first Idaho
record). The bird was in the row of Olive/Willow/Cottonwood trees that run
east/west and parallel camas creek about 1/4 mile west of headquarters.”
