Mysterious 'whooping' and 'screaming' was heard across a small Connecticut town, which some believe came from the long-rumored but elusive creature Bigfoot.

The haunting episode, reported by a California visitor to New England, did not sound like a 'bobcat/fox/coyote,' according to the witness, who came forward because the calls resembled past cases of alleged 'bigfoot whoops' posted online.

'I'm well acquainted with coyotes, bobcats, and cougars and their vocalizations,' the witness said. 'This voice had quite a bit of "power" behind it.'

The 'short duration screaming' and 'long-duration whooping' were said to be heard just after midnight, roughly eight miles from Collis P. Huntington State Park, an 883-acre wilderness preserve east of New Haven.

The Bigfoot Field Research Organization (BFRO), which obtained the witness's account, categorized it as a 'Class B' case, meaning that it was a second-tier sighting below 'Class A' but a credible report despite the lack of corroborating evidence.

'All the dogs in the area started barking at once when the vocalizations ended,' according to the witness report. 

'Normally there are many owls in the area and when I had gone outside previously I could hear them.'

'When I had noticed the [alleged Bigfoot] vocalizations had ended it was probably a good ten minutes before I could hear the owls again.'

While no devoted skeptics have tackled this specific case, many have previously criticized alleged Bigfoot audio cases, as have even a few noted Bigfoot believers like the late Washington State University anthropologist Dr Grover Krantz.

'Temperature, wind and geographical features such as canyons' can all alter animal sounds from a distance, making them sound more odd, according to noted skeptic and author Benjamin Radford.

But solutions to the Connecticut ear witness case, submitted on October 20, 2023, and published by the BFRO are still lacking — and the mystery resurfaced this week with coverage by local ABC affiliate WTNH's News 8.

News 8 noted that this was not region's first brush with Sasquatch, citing reports from 2018 in Hartford County, Litchfield County in 2022, and Middlesex in 2019. 

'New London County’s in 2019 and Windham County last reported seeing a bigfoot in 2009,' the news network said.

'The sound direction seemed as [if[ it was from the Northeast of coords,' the witness wrote. 'Vocal pattern would be roughly 10 seconds of vocalization then stop.' 

'This repeated four or five times that I was aware of. It may have been going on prior to me noticing it,' the witness continued. 'This went on for about five to ten minutes.'

By the witness's best estimated, the strange whoops and screams were originating from 'two klicks' or about 1.24 miles to the east, away from the state park toward New Haven, home to Yale University. 

But, the BFRO — which also hosts a page of sound recordings believed to be Bigfoot as well as audio of coyotes for contrast — did not post witness audio in this case.

DailyMail.com has reached out to the BFRO to inquire about what specific Bigfoot 'vocalization recordings on YouTube' were heard by their witness, leading them to believe that their Connecticut 'whooping' case resembled past reports.

Serious proponents for the existence of an undiscovered North American primate, like Idaho State anthropologist and primate anatomy expert Dr Jeff Meldrum, have taken increased interest in animal call recordings that might prove to be 'Sasquatch.'

The most compelling acoustic case, according to Dr Meldrum, is the 1970s 'Sierra Sounds recording,' captured by businessman Ron Morehead and journalist Al Berry.

Audio analysis of the Sierra Sounds by an electrical engineering professor at the University of Wyoming, Dr Rodney Kirlin, concluded that these bizarre 'abnormal whistles' might be 'a unique observation of Bigfoot in his natural environment.'

But further evidence is still being sought to confirm any link between the unusual harmonic acoustics in that Sierra case and last October's Connecticut 'whooping.'

Two years before Connecticut's 'Class B' case, Idaho State's Dr Meldrum spoke publicly about the 'Sierra Sounds' alleged Bigfoot audio, which he argued was 'head and shoulders' above other acoustic evidence for the popular cryptid.

The primate anatomy expert focused on 1980 research into the audio, conducted by Dr Kirlin and fellow electrical engineer Lasse Hertel and anthologized in 'Manlike monsters on trial: early records and modern evidence' after their work had been presented at a conference held by the University of British Columbia.

'Kirlin and Hertel,' Dr Meldrum noted, 'they're not linguists or biostatisticians, but they have skills in sound analysis.' 

While stopping short of claiming the audio is proof of Bigfoot's existence, Dr Meldum noted that some of the harmonic tones on the tape, which were reported to be heard from a distance, resemble those of certain great ape species.

'That was fascinating to me because that actually suggests the potential for some, extra laryngeal air sacs in the Sasquatch, which wouldn't be unexpected at all because they're present in the other three groups of great apes,' Dr Meldrum said.

'They're seen in chimps and gorillas, to the greatest extent in the orangutan, to the least in the chimp,' Dr Meldrum told the podcast Strange Phenomenon. 'In humans, they're very rare, but they do pop up every once in a while.'

Describing the 'abnormal types of whistles' found on the audio, Dr Kirlin and Hertel noted that 'very short vocal tract lengths were estimated.' 

'These whistles could either have been produced with some kind of a musical instrument or by the creature using only a part of its vocal tract,' the duo wrote.

All three researchers, as well as Bigfoot skeptics, have noted that the creepy audio heard on the Sierra Sounds may instead derive from a noise much closer to the microphone creating a saturation error effect.
