For two days in late October, 2013, an unseen vocalizer made loud
moaning howls, whoops and wood knocks in the hills near Bruno, West
Virginia. A local resident managed to capture four clips of that
vocalizer with their cell phone, and those clips were quickly shared
with the BFRO. This video spectrogram is an illustrated playback of the
vocals captured in those clips. They are fairly to exceptionally clear,
but head phones are recommended to achieve the best possible listening
experience.
