Bigfoot Whistle Starts Coyote Packs, Pennsylvania Expert Reveals

There's something fascinating happening over in Pennsylvania, and a recent interview on the Creek Devil channel with host William Jevning dives deep into it. The guest? Mary Fabian, founder of the Pennsylvania Bigfoot Project, a Facebook community that's grown to over 17,600 members strong. What makes this group stand out isn't just the sightings they document—it's the people behind them. Mary explains that a huge part of their mission involves helping witnesses dealing with PTSD, giving them a safe space to share experiences that often change their lives forever. One of the most impressive things Mary discusses is the group's initiative to open county chapters across Pennsylvania's 60+ counties. The idea is simple but powerful: get locals involved in researching and investigating sightings in their own backyards. Town hall meetings, campouts, and boots-on-the-ground fieldwork are all part of the plan. With over 50 years of personal experience and three sightings of her own in western Pennsylvania, Mary knows exactly how important it is to have a network of people who take these encounters seriously. The conversation takes a wild turn when Mary describes hearing Bigfoot just the other night. Not just hearing them, but witnessing their interaction with coyotes. According to Mary, these creatures will start with high-pitched whistles—almost like they're signaling—before the coyote packs erupt into howls and yips. Sometimes that interaction ends with a sharp yip, and Mary suspects that's the sound of a coyote meeting its fate. It's a hunting strategy that speaks to intelligence and patience, something researchers have noted about Sasquatch behavior for decades. The idea that they can manipulate other animals in their environment fits with countless reports from across the country. That brings up another chilling topic: coyote and dog remains. Mary mentions a research trip to Tennessee where team members found a coyote body twisted like an old dishrag. The kind of damage described requires opposable thumbs and powerful hands—something no known predator in North America possesses. William brings up a similar pattern where Bigfoot have been known to mimic dogs, luring them outside where the dogs bark relentlessly. Once the dog is out, it's often a fatal mistake. The theory? The barking gives away their location, and the creatures don't appreciate the noise. Mary has heard of this happening, though she hasn't received specific reports from Pennsylvania. The discussion gets even more interesting when they compare this behavior to other primates. Forest chimes in with a fascinating parallel from India, where langur monkeys—after losing an infant to a pack of dogs—went on a campaign of retaliation. They picked up puppies, carried them up into tall trees, and dropped them. Multiple times if needed. These aren't carnivorous primates, yet they understood that height could be lethal. The vindictiveness, the calculated response, the memory of loss—it's all very human, and it suggests that Sasquatch operate with similar emotional complexity. Mary shares a personal story that's hard to forget. While camping at Salt Fork State Park in Ohio, her dog was on a 20-foot lead near the edge of a bluff. Around 10 at night, the dog squatted to do her business, looked down over the hill, and came tearing back with a look of pure terror. Ears laid back, tail tucked—this wasn't a dog spooked by a deer or a raccoon. Whatever was down there left a lasting impression. Stories like these are why groups like the Pennsylvania Bigfoot Project matter so much. They give witnesses a place to be heard, and they help piece together patterns that might otherwise go unnoticed.

William Jevning has been in this field for over 40 years as a two-time witness and researcher, and his interviews consistently bring out incredible stories from people who've had real experiences.
