In my opinion, these recordings aren't particularly useful. I have above average high range hearing and I can barely discern the calls and certainly can't hear enough to assign the sound to a species.

Please let me know if you think it's something else, and I will learn accordingly. (please ignore the visual portion of the 'videos' and I realize the call in question is tough to hear, but it's there)... High pitch call at ~6 & 18 seconds... https://www.youtube.com/watch?v=pSBczeVTKlg High pitch call at ~5/6 & 13 seconds (and my dog panting)... https://www.youtube.com/watch?v=A6pYr3ZUgL0 ColbyPDX On Tue, May 6, 2014 at 9:27 AM, Dwight P <gpic4dp@xxxxxxxxx> wrote: Monday evening at least four individual SWAINSON'S THRUSH were heard singing at Jordan Woods Natural Area in the Cedar Mill neighborhood in Washington County.
