In the field of Bigfoot research, it’s rare that an investigation yields data worthy of deeper scientific analysis. But that’s exactly what happened during the 2023 expedition to “Research Area 1,” What started as a routine night surveillance operation turned into something far more intriguing—a single, clear, and oddly powerful vocalization that sparked questions no campfire story could answer.
Let’s cut to the chase: we recorded a “whoop.” Not just any whoop, but one with acoustic properties that stand apart from typical human calls and bear strong similarities to vocalizations of large-bodied primates.
We broke this down in a recent scientific paper, comparing the vocalization’s spectrogram and frequency analysis to known calls of humans, chimpanzees, gorillas, and howler monkeys. Here’s the kicker—the whoop was centered in a lower frequency range, averaging around 156 Hz. That’s significantly deeper than most human whoops, and well within the realm of some non-human primate vocalizations. We're talking frequency territory typically inhabited by gorillas or howler monkeys, not hikers or pranksters.
And no, there are no known non-human primates in that area.
To make things even more compelling, the context of the recording lends it additional weight. The whoop occurred shortly after I attempted to announce my presence, as I had for years prior, using vocal calls and whistles; methods also used in primate research to elicit response behavior.
Coincidence? Possibly. But it’s one hell of a coincidence.

The original archive entry offers a boots-on-the-ground account of the event, but when paired with proper signal analysis and primate vocal studies, it becomes something more: an anomaly grounded in data. Not definitive proof, but evidence that demands attention and further study.
What makes this case stand out isn’t just the quality of the audio, but the scientific rigor we applied afterward. This wasn’t brushed off as “just another sound in the woods.” It was analyzed, compared, and documented with transparent methodology.
In a field often plagued by hoaxes and hyperbole, this instance stands as a model for how Bigfoot research should be conducted: evidence-based, technically analyzed, and open to peer review.
Whether you’re a die-hard believer, an open-minded skeptic, or a hardcore primatologist, the 2023 whoop is worth a listen and more importantly, it’s worth a look through a scientific lens.
