On an early morning walk through Norwood Park in Bethesda this morning, my wife and I heard and then saw a songster high in the canopy. The persistent song sounded like "tweedle deedle DEE," with the last syllable higher than the rest, occasional interspersed with an isolated tweedle.  We were looking almost straight up at it and never could see the facial markings. It had a medium-length thin straight beak. It had a spotted buffy breast, but the spots were confined to the upper part, extending down the sides of the breast but not the center. At first we thought veery because of the spotting, but the voice seems wrong (ascending, not descending, at the end). We finally settled on Swainson's, though the song was rather different from the recording on the Stokes CD.  Any thoughts?

Thanks,
