Heard it chipping in the brambles here: https://maps.app.goo.gl/y28MMx2EVgYnw6J88. Merlin was running & ID'd it immediately as Wilson's Warbler. Then it popped up on a perch. Small, yellow warbler, greenish back, black eye on a yellow face, distinctive dark cap. Chipping continuously. It flew to the colorful maple at the nearby edge/corner of the beaver pond. I could hear it chipping there. I used Audacity to edit the audio file to remove noise and amplify the audio.
