Подробности наблюдения

Presumed continuing bird seen by Phil Davis 5/4. Northern most Ravine down in swampy undergrowth. Heard only. Fairly rich steady trill type A. Unlikely to be chipping sparrow. Will try to add spectrogram but as always traffic nearby makes it poor quality. I actually rode bike around and to bottom of ravine to find it. Much poison ivy but by the time I got there it was silent.
