The New Howl - A Demonstration of Sasquatch Vocal Range and Lingual Dexterity

On various websites around the Internet witness reports have described loud vocalizations that were initially mistaken for a siren due to the sheer volume and tone of the call. But as the vocals played out, most witnesses come to realize they are listening to an organic sound, and not something mechanically generated. Until recently, few recordings existed to demonstrate that characteristic however, beyond those of John Andrews and Darrold Smith. Fortunately, some new examples of "horn-like" or siren-like vocals are being captured around the country in such diverse locations as Washington, West Virginia, Kentucky, Virginia and Mississippi.

This amazing clip of a loud vocalizer was captured by "Jolie" at 3:41 a.m. on February 10, 2009, outside of Hattiesburg, Mississippi. To protect Jolie's privacy we are leaving out her last name. To the casual listener the clip sounds like a bizarre mechanical cacophony, almost like hydraulic machinery under stress. But when we put on the head phones, pay close attention, and scrutinize the spectrogram of this recording, several telltale characteristics emerge including falsetto notes, abrupt pitch changes, attenuated fundamental frequencies and integrated wood knocks.

The metallic sounds of the higher notes in this clip have a brassy tone, almost horn-like. This unique call is difficult for humans to replicate organically and is not commonly known to be produced by other North American mammals. The evidence that sasquatch are capable of such uniquely cryptic vocals are another intriguing element of study in the realm of this poorly understood creature.

This is not the first time these mechanical/metallic tones have been captured, but this is one of the clearest examples that also contains other important sasquatch indicators. It is recordings such as this that help us understand descriptions from witnesses, such as the metallic "ping" vocal reported in this BFRO report: "Hunter remembers his lengthy daylight sighting through binoculars near Dora". With time, more of these vocals will emerge and be added to the growing lexicon of sasquatch vocalizations.


  1. Hey M,
    This one is a real stunner; just amazing. The impression my un-trained ear gave me was of a vocalizer with an exceptionally large set of lungs to produce such fullness and depth along with incredible power / volume compared with some of the weaker vocals I've heard. Sort of like the difference between a bass guitar played through my 15 watt practice amp vs the same instrument fed through a Marshall stack. Have you ever gotten any sense of whether such resonance and volume is proportional to sheer overall size of the vocalizer? I guess that's a stupid question as I assume that would be the case. Was just wondering if anyone had ever been in a position to verify the hypothesis. I would have loved to hear it in person but I got chills listening to it from the security of my house. I imagine it would have been horrifying to hear it alone deep in the woods during the middle of the night. Would have worked like the brown note for me no doubt! Great work as always. Talk to you soon.

  2. Hey Hankd, yes this is a spectacular vocal and the size of the vocalizer really comes through in these howls. There are techniques for estimating lung capacity and vocal tract length, and that will be one of the next steps in the study of vocals such as these. Hope you're having some luck recording in your neck of the woods, cause they're out there.
