The vocalization captured in this recording remains inexplicable, if for no other reason than its incredible power and duration. With that said, the vocalization is kindred to many other howls attributed to the wood ape from around North America, as well as many others empirically observed and documented—although not necessarily recorded on audio devices—by the NAWAC / BFRO. It is multi-tonal. There may be other such howls recorded that remain hidden away in audio files not yet examined.
