Date/time (local)OccurrenceLatitudeLongitudeNotes
07/21/25 04:48:27Detected49.4743-64.6169Probable BW downsweeps throughout the period; the last call in P14 is a low amplitude downsweep with downward concavity, indicating BW presence.
07/21/25 05:03:27Detected49.4741-64.6165Downsweeps in P4, 13, & 14; the calls in P4 & 13 have downward concavity.
07/21/25 14:33:27Possibly detected49.4934-64.6399Short low amplitude downsweeps in P10, 14, & 15; although the second call in P10 appears to be concave-down, due to its low amplitude, this is difficult to confirm, so this period has been scored conservatively (PD).
