09/16/26 00:34:30Possibly detected62.1874-31.2852P7/9/15- BW classifications (CT40), concavity unclear for two, possibly concave down in P7 but short P6/10/13- CT17 classifications, same frequency as BW classifications and similar shape
09/16/26 00:49:30Possibly detected62.1875-31.2851P2&9- BW classifications (CT40), concavity unclear, P2 classification is not isolated, but high amplitude. P9 classification is short and shape isn't good P3/5/6/7- unclassified possible downsweeps, concavity unclear

Date/time (local)LatitudeLongitudeNotes
09/16/26 00:04:3062.1874-31.2854P11- BW classification (CT40), short, low amplitude, can't be certain it is actually biological
09/16/26 00:34:3062.1874-31.2852P7/9/15- BW classifications (CT40), concavity unclear for two, possibly concave down in P7 but short P6/10/13- CT17 classifications, same frequency as BW classifications and similar shape
09/16/26 00:49:3062.1875-31.2851P2&9- BW classifications (CT40), concavity unclear, P2 classification is not isolated, but high amplitude. P9 classification is short and shape isn't good P3/5/6/7- unclassified possible downsweeps, concavity unclear
09/16/26 02:34:3062.1876-31.2845P10&11- possible downsweeps ~50Hz, short
09/16/26 16:04:3062.3751-31.1935P8&9- potentially biological short pitch tracks in repetition, INI~12.5
09/16/26 16:19:3062.3751-31.1936P5- potential short downsweeps ~50Hz
09/16/26 18:49:3062.3749-31.1938P5 to 10- fuzzy cat- many repeated pitch tracks ~20Hz, no more than 3 consecutive classifications in a pattern, INI~13 P13- upcall shaped unclassified pitch track, low amplitude, ~60-100Hz, isolation is okay, but no other calls like it in the period
09/16/26 20:34:3062.3748-31.1939P15- upcall shaped pitch track ~150Hz, isolation is good, amplitude is low, no others like it in the period, may be noise
