Observation details

Couldn't get a good visual, heard a chip note that piqued my interest while walking by, near the overlook area over South Garden. Skulky small bird that was calling, but Merlin didn't pick it up in the app. Eventually went silent, and shortly after I thought that I saw a Common Yellowthroat fly out of the shrubs, which definitely did not sound right for the chip calls. Figured it might have been a second separate bird, but feedback from Discord brought Mourning Warbler to my attention as the possible culprit. Uploading the audio for reference.
