Date/time (local)OccurrenceLatitudeLongitudeNotes
07/26/26 01:51:16Possibly detected44.0052-67.9229P4 has 2 MF calls that align with HW. There are some high amplitude calls on P9, appears to mostly be artifacts. Just making note of that. P4 is where the evidence for HW is seen.
07/26/26 02:21:16Possibly detected44.0050-67.9277P2, P4, and P6 have high amplitude, U-shaped MF downsweeps. Marking as PD for HW. Another possible LF HW call on P10, not as obvious but the call is isolated. Either way, does not exceed 5 calls to meet the Detected criteria.
07/26/26 02:51:16Detected44.0049-67.9324P8-P10 I'm counting 6 MF downsweep HW calls. 2 of them have artifacts attached, but are still convincing.
07/26/26 03:36:16Possibly detected44.0093-67.93422 clear MF downsweeps on P8. P4 has some loud HF sounds, most of what is there is artifacts. Hard to say what it is. Artifacts give it a very straight look. on P16, LF upsweep and lower amplitude compared to P8. Don't think its RW. Making note for second opinion because it is isolated. Clear HW context on P8.

07/26/26 03:51:1644.0112-67.9350Very short HF sound on P11. Doesn't appear to be biological, making note because of the high amplitude.
07/26/26 04:06:1644.0132-67.9357Classified RW on P9. Has the LF straight pitch tracks under it, the upsweep shape is small, too straight with artifacts. Not RW upcall. Short MF downsweep on P13. A lot of unclassified LF sounds are associated with it. I think its likely HW, don't think it should be marked PD with all the noise associated with it on P13. Leaving as ND.
07/26/26 05:21:1644.0228-67.9393Unclassified LF upsweep on P2. Technically, it is two pitch tracks close together as there is a small gap between them. Don't want to assume they are associated, but appear to be part of the same call. Has the shape of upcall, frequency is a bit low for one. Mostly isolated, there is some noise around it. No obvious HW context here, there was about 1 hour prior to this.
07/26/26 07:36:1644.0443-67.9390P8 has a small MF low amplitude upsweep. 2 small LF upsweeps on P13. Higher end of low amplitude. The first one has not artifact, the second one might. They are close together, ~2s between them. Leaning towards PD for HW, but not positive.
07/26/26 08:21:1644.0460-67.9398P6 has a short, LF, and low amplitude upsweep. Possible harmonic with it, artifact has higher amplitude than the call itself.
07/26/26 08:36:1644.0473-67.9407Possible HW on P14, too many artifacts associated with it, not very convincing.
07/26/26 09:51:1644.0528-67.9446Classified RW on P16, just noise with a slight upsweep shape and straight LF noise under it.
07/26/26 11:21:1644.0511-67.9563P11 and P12 have 2 classified FW calls. A lot of LF noise around here, some of which could be unclassified FW, but seems unlikely and is not convincing as such. Leaving as ND.
07/26/26 17:06:1644.0645-67.99574 classified FW pulses on P10 and P11. Spaced out either too far apart or too close together, and associated with a lot of LF noise in both panels. Leaving ND.
