He was only showing off his wild side.

Bigfoot was caught making a ruckus in Connecticut’s Sasquatch hotspot last year, according to a recent report by The Bigfoot Field Research Organization.

A Fairfield County resident heard the hairy giant’s “screaming/long-duration whooping” just after midnight on Oct. 17, 2023 — sparking a barking dog frenzy and sending owls into a terrified silence.

“This voice had quite a bit of ‘power’ behind it and I could tell that it was carried over distance. I would ‘rough’ guesstimate at least two clicks [1.25 miles] from my coords,” the anonymous witness said in the report, which was published this summer.

The Yowie howls emitted from a forested area near the town of Monroe and lasted up to 10 terrifying minutes, according to the witness.

The alleged Bigfoot would yelp for roughly 10 seconds and halt before repeating the pattern — which the reporter claims matches other Sasquatch recordings captured and shared on YouTube.

“All the dogs in the area started barking at once when the vocalizations ended. Normally there are many owls in the area and when I had gone outside previously I could hear them,” the witness stated, adding that they were certain the noises did not come from a coyote, bobcat, cougar or fox.

“When I had noticed the vocalizations had ended it was probably a good ten minutes before I could hear the owls again.”

According to BFRO investigator and founder Matthew Moneymaker, the report wasn’t shared for nearly a year because it was a sound-only report — but a probe found the claims credible enough to land a Class B categorization.

The incident occurred with close proximity to a railroad bed and powering route that extends to locations of other sightings — including one from February 2022 in which a woman allegedly saw a “very tall large all-black upright figure” chasing 30 deer through her backyard in Bethel.

“My first thought was this is either a person or a bigfoot. I did a quick checklist in my head and ruled out person,” the witness said.

“It was solid black from head to toe with no color differences. It was also too large to be a person. I had a size comparison with the deer ran just past it. The black figure was about 2 and a half times the height of the deer torso. It must have been between 8 and 10 feet tall.”

Moneymaker said the October 2023 incident was deemed credible after ruling that species known in the area would not have been able to emit the “strange unidentified sound” that was reported.

“I contacted the witness to make sure the person was real and whether more of the sounds were heard at the location,” Monekymaker told The Post.

“He heard a loud howling sound that is distinct from other animals, but consistent with a bigfoot. It happened in an area with a history of sightings extending back decades. The area has the main ingredient present at other sighting locations: An abundance of deer in the area.”

The sighting marks the fifth Sasquatch sighting in Fairfield County since 1953.

Connecticut is seemingly a playground for Sasquatches, with 25 total sightings reported over the past seven decades, according to BFRO.

Litchfield has the most sightings of any county with 11, the most recent of which occurred in the summer of 2022.

A retired police officer reported hearing roars and yips in a similar, repetitive pattern to what the Fairfield County resident would describe just over a year later.
