In response to this invitation in the original post, I suggest distant
Black Oystercatcher. That was my response invoked instantaneously &
instinctually when I heard the recording. After listening to the
comparative recordings in the interesting responses as well as other
recordings, particularly weaker BLOY recordings possibly from a distance, I
still tend toward BLOY over WREN--pitch, structure, and harmonics are, I
admit, surprisingly similar for that single call, but delivery pattern
favors BLOY in my experience: lounging individuals often deliver a single
call at low intensity and intermittently as if throwing the question to the
wind whether any conspecifics are around. Also, habitat, right? I would
not be inclined to use this recording alone to confirm a Wrentit in WA.

I guess I'm surprised no one else yet reported that Black Oystercatcher
feeling in their bones upon listening to the recording. Maybe it's me
missing something!
