Commentaires
Night chorus of numerous individuals probably 100ft away. The birds would call off and on all night for unknown reasons, possibly just letting others know where they are, as the threat of nocturnal predation is minimal. I think the night calls have a slightly different quality than the typical calls made during the day but I'm not sure if there is any significance to this. Amplified and 96 hz high pass filter with Audacity.
