Heard calling spontaneously near 37.848401 / -121.789619, which is inside the East Contra Costa Christmas Count circle. After it stopped calling on its own, it responded to a Merlin recording of Canyon Wren calls by calling vigorously but it did not come in closer to allow for a better recording. It is still discernible (at max volume) in the attached audio file.
