I used http://identify.whatbird.com/mwg/_/0/attrs.aspx (visual/audio cues search) to try and narrow down choices ... to no avail. They now have two "song/call" options to help reduce number of possibilities.
Thanks to all that chimed in with possibilities-guess I'll chalk it up as a "miss" (so I can get some sleep).
