What was detected
- Long-eared bat · closest match Plecotus austriacus of 2 · 3 calls · 16.5 kHz · strongest 0.344Measured 16.5 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 · 2 calls · 20.6 kHz · strongest 0.331
- Soprano pipistrelle (Pipistrellus pygmaeus) · 2 calls · 53.2 kHz · strongest 0.62
BSG-BAT and Kaleidoscope disagree. BSG-BAT identified Lesser horseshoe bat instead. Kaleidoscope identified Brown long-eared bat instead.
