Hi Skip,

I don't know what this is off the top of my head. However, I would quibble
with your description of a 4 quick & 2 slow cadence. Listening to it and
looking at the sonogram, I hear/see a 3 quick & 3 slow cadence. I don't
know if that helps.

My first thought was MacGillivray's Warbler because they do a 3 high & 2 low
song, which can vary. I once chased a mystery singer at Ladd Marsh by
LaGrande. It was doing a weird song over and over. When I finally saw it,
it was a MacGillivray's.

Another thought: Hermit Warblers songs can end on a down-slurred "SEE-unk,
SEE-unk." The ending of your mystery song sounds like that to me.

While birding at Ridgefield NWR, I heard a song I couldn't place. I

posted it as a mystery on xeno-canto, but so far no takers.

You can hear it here:


That's "" in case the link gets garbled in

translation. Weird song of an expected local or something lost? The

only birds I can think of are tropical and not really candidates.

I'm wondering if this rings a bell with anyone out there in obol-land?

Happy birding,
