Audiomoth vs Parabola

Audiomoth vs Parabolic mic: Moorhen

Two sets of kek-kek-kek calls of a flying Moorhen recorded in parallel with an Audiomoth (high gain setting) and with a Dodotronic Hi-stereo mic linked to a Zoom H4n Pro recorder (90% record level). The spectrograms show that both calls are detected by both recorders, though the first more distant calls are less distinct with the Audiomoth. Note also the Robin singing in a neighbouring garden is almost invisible on the Audiomoth recordings (a benefit, some would say!).

For direct comparison, here’s a video of the calls back to back.
