Date/time (local)OccurrenceLatitudeLongitudeNotes
07/22/26 11:33:02Detected48.5359-62.0567P2- high amplitude, classified BW (CT44) arch call. P3+P9- very short, possible downsweeps at ~50Hz. There is enough information to be D BW
07/22/26 11:48:02Possibly detected48.5359-62.0567P4- very short, low-mid amplitude, possible downsweep. P5- low-mid amplitude, short, unclassified downsweep with slight upward concavity. P11- mid-high amplitude, very short, classified BW (CT40) downsweep that is tonal at the end. Scoring BW conservatively due to the very short nature of the classified BW downsweep

Date/time (local)LatitudeLongitudeNotes
07/22/26 00:48:0248.5378-62.0797P15- very short, low-mid amplitude, possible downsweep
07/22/26 01:03:0248.5379-62.0796P4+P7+P10- high amplitude, very short, possible downsweeps; P10 is slightly concave down but it is difficult to be certain due to length.
07/22/26 03:48:0248.5393-62.0788P3- mid-high amplitude, very short, possible downsweep
07/22/26 06:33:0248.5058-62.0282P7- very short, low amplitude, possible downsweep
07/22/26 10:33:0248.5360-62.0566P8- low amplitude, very short, possible downsweeps
07/22/26 10:48:0248.5360-62.0566P5- very short, mid amplitude, possible downsweep. P6+P9- high amplitude, short downsweeps with upward concavity; P6 is classified as call 17 and P9 is classified as SW (CT1).

07/22/26 13:03:0248.5357-62.0568P13- high amplitude, short, unclassified downsweep with very very slight downward concavity, but it is difficult to be certain.
