At least two, possibly three individuals. Early morning saw one individual in the clearing between Bill’s Woods and Biocore Prairie, showing yellowish wash to throat and belly (photo attached). Late morning had two giving the “winter” call together at the end of the paved path down to Picnic Pt Marsh. Differentiating this call from Acadian: it peaks at 6 kHz, whereas Acadian’s “pweet” call usually peaks higher (see https://xeno-canto.org/forum/topic/6457 for discussion), and the spectrogram shows a relatively symmetrical peak (photo attached) whereas Acadian’s “pweet” is less symmetrical with a stronger upward slope and weaker downward slope (thank you to JN for the ID help). This second location is only 0.2 miles away from the morning spot, so I’m counting this as two rather than three birds to be safe.
