Natural "song" by one of at least three calling Black Rails recorded by Curtis A. Marantz at 8:05 pm on 13 April 2022 along the north side of West Pond, Imperial County, California. Unseen bird was estimated to be about 30 meters away and through what appeared to be a dense thicket of Giant Cane (Arundo donax) and likely other emergent vegetation along the northern edge of the pond. Clear, calm, 63º F. Nearly full moon about 70º up in eastern sky, High-pass filter on microphone, but not on recorded, and further filtered below 100 Hz using Audacity 2.3.3.
