It was established by Dr. R. Lynn Kirlin, University of Wyoming, that the Sierra sounds recorded by Al Berry of reported bigfoot showed no sign of being altered. The year long study also showed that there were no signs of re-recording or pre-recording of the tapes. The voice range of these creatures go beyond the range of an average adult human male. This would suggest that these creatures could mimic many different sounds.
It was later discovered by Dr. Kirlin that the whistles from these creatures were made through the vocal cavity. The following whistle (72a)
The following sounds were taken from the archives of Ron Morehead.
Often, usually at dusk, these creatures would approach the Sierra camp and would announce themselves with a beating or
beating or rapping sound (74a):
An extraordinary vocal exchange between a Bigfoot and Ron Morehead happened two years after the Alan Berry recordings that were used in the production of the CD. A definite rapport had been established and for the first time these creatures vocally responded to the men while they were outside the shelter. Only two men made the long trip to the camp, Ron Morehead and Bill McDowell. The Sierra camp is not in an area that you can drive to. It is an eight mile hike into a very difficult country.
The evening began at dusk with these creatures’ rhythmic rapping and then “whooping” toward the men. Ron Morehead decided to respond with his on “whoop” and thus began a vocal exchange that lasted over an hour. (74b)

It’s been 2 or 3 years since I talked to you and your daughter at the Bigfoot (Satsquatch) Symposium in Eugene OR. I have done much research (reading over 15 factual books) and found that BF can totally paralize a
courious witness as what happened to U and UR daughter. Have U ever experienced “Mental Telepathy” with a BF evolving in speech and feelings in UR mind?
Please keep me updated on any bigfoot activity. We live in the NW corner of New Jersey–Hopatcong. Some have had sightings in our area near Maxim Drive near Bear Pond and Lake Hopatcong, NJ years ago. I have not seen anything but have heard howling way in the back of the woods off of Maxim Drive near Bear Pond in the 70′s. Trudy Odermatt had her house built up there–the only one around at that time and when she had her wrap around deck built years ago, she would not put stairs on it. When we asked her why she did not want stairs down to the forest floor, she waid she was ALWAYS afraid of something climbing up. She ALWAYS heard howling and moans from the woods that lead way onto the shores of Bear Pond! I don’t think current building codes would allow you to leave the stairs off but she did NOT put stairs on that deck. This was in the 70′s. Her house is right off of Maxim Drive…it is still there. She got a huge black dog, part Rottweiler, part Doberman that stood very tall…she was still afraid, so was the dog. Liz Carreno
I would like to say i have found a new found adult fascination for bigfoot in my older years since the show has come out. From watching alla ive seen i noticed that sometimes bigfoot is lean and younger and taller. He walks like a regular human being. Its really hard to put together the two sides of bigfoot when you see him walking like a regular person with a smooth casual stride in videos, then you hear these gut wrenching screams and the language they use when doing SAMURAI talk. When they have converstaion or make those growling grunt noises it stuns me to no end. They sound like an APE but THEY ARE NOT! they are PART HUMAN and PART APE. in my mind for sure.. its very hard to put the two together when you see the one walking in the new 1962 video from FINDING BIGFOOT. This is the strangest scariest feeling but its TRUE. People dont believe this but maybe its better becuase we need to preserve WHATEVER IT IS and whoever. Id love to know its origin and how did an ANIMAL AND MAN breed to get this creature made of ANIMAL AND MAN. thanks for all the recordings its unreal… now i know we have some right near where i live in WELLSVILLE, OHIO… probably route 39…. its just across the bridge from me and im in west virginia…. take care and we need laws to protect this creature…. i do feel they are agressive for sure. people need to be careful… they have agressive moments,feelings and decision making reasoning… if they can reason, they can get mad! being chased out of the woods would not be a good thing if i were hiking! everyone be careful if youre going looking! marla
just to leave some information my brother 40 yrs ago went with friends and they all claimed they saw a figure 9 foot tall, red glowing eyes hes was very muscular, With hair all over,Now my brother could nomore tell a lie if his life depended on it.And all of his friends told the same story,They were each carrying flashlights so each one showed a diffrent area at first untill my brother pointed him out, iam 60 my brother is 62 now.Back then noone talked openly about bigfoot .
Eee Yikes. Try to Keep it together.
Many animals can imprint on human beings. They remember. I’ve had Barred Owls that I’ve called up that can see I’m not another owl and yet, the very next night will begin to call for me to come outside and speak with them. This was back before I found out that this was considered to be wildlife harassment and was unlawful, so I quit doing it for the owl’s sake.
It’s understandable that a creature such as Sasquatch would be capable of communicating with a human being and able to recognize certain individuals so that it would know who is friendly and who’s not.

i too have mimmicked a scream howl sound in mn here and have 4 other people that can vouch for me and were there next to me as i screamed back it was so loud it echoed and i did it for about a half hour or so as it got very close and a lil scary because i heard small branches break it was in the woods about 50 yrds or less then it just quit when it got close it was around 2-3 in the morning
Can a person have a relationship with bigfoot? I feel they are like any wild animal in the forest. You have to take your time to know them. People have stupidly shot at them and they know humans can do harm so they have no trust in us. They then do all they can to protect themselves from us.
What kind of food do they eat? How do they kill the animals they eat? They seem to be compassionate at times. I have read too that they come running after people and scratch them. I don’t know if this is true.
Given that “Bigfoot” is assumed to be a large bipedal primate, one only needs to look at examples of other primates to really answer the question: “Can a person have a relationship with Bigfoot?”.
I would say: yes. It’s not only probable, but entirely possible. There is an entire family group in Africa that has adopted Jane Goodall as one of their own. She had to work at it, though, for months at a time. She was only a young college-educated woman in her 20′s at the time. Yet, it is because of her that we know so much about Chimpanzee’s. Why couldn’t someone do the same with “Bigfoot”? If you’re in the same area, they’ll know the sound of your voice, recognize your scent, and learn your patterns. Just because you can’t see them doesn’t mean they can’t see you.
As far as diet, one would think their diet is as varied as their environment. Sasquatch in the Pacific Northwest likely eat a lot of fish, mollusks, berries, nuts, leafy greens, and probably human leftovers on occasion. In Pennsylvania, the diet will be completely different. Likely, rabbits, small birds, berries, mushrooms, and things of that nature. The fabled “Swamp Ape” of the American Southeast could probably dine on a delicacy of alligator once in a while. They’re probably strong enough to do kill one if they can catch it out of the water. Generally, though, I would assume the running consensus is that a large bipedal ape would certainly have to be omnivorous or likely wouldn’t survive very long in the variety of climates it is believed to live in.
As a primate, they’re our cousins and really not that much different from us in too many ways.
Fixes to the above post:
“There is an entire family group of Chimpanzees in Africa that has adopted Jane Goodall as one of their own.” (They’ve also known her for 3 documented generations, which lends credibility to the idea that chimpanzees have some form of “word-of-mouth” knowledge inheritance from their elders. It’s only a hypothesis, though.)
“They’re probably strong enough to kill one if they can catch it out of the water.”
“Generally, though, I would assume the running consensus is that a large bipedal ape would almost certainly have to be omnivorous or likely wouldn’t survive very long in the variety of climates it is believed to live in.”
