What was detected

Soprano pipistrelle (Pipistrellus pygmaeus) · 13 calls · 53.2 kHz · strongest 0.78
Long-eared bat · closest match Plecotus austriacus of 2 · 2 calls · 16.7 kHz · strongest 0.311
Measured 16.7 kHz is far outside the expected range for this label. Flagged for review rather than corrected: this measurement is not precise enough to name an alternative. This is a protected species, so the claim is held back.
Noctule, Leisler's or serotine · closest match Nyctalus noctula of 3 · 1 call · 27.4 kHz · strongest 0.297

Kaleidoscope disagrees. Kaleidoscope identified Brown long-eared bat instead.
