Since 2004 a group of people from Michigan, Ontario, and Indiana have been conducting an on-site research project in Michigan in an attempt to document evidence of unclassified wildlife.
An important aspect of our research in this location has been a program of bioacoustic surveying. This program has proven highly successful and has resulted in several hours of medium to high quality audio recordings of anomalous wildlife vocalizations and apparent physical manipulation of the immediate environment.
Prior to now we have limited the sharing of these recordings to a handful of people, however both the landowner and we have wondered who else might be experiencing these types of events, and so with the property owner's blessing and with his interests in mind, we are now releasing some of the audio recordings acquired over the last several years.
Our reasons for deciding to release some of the recordings are two-fold:
First we would like to determine if similar vocals and sounds have been heard and/or recorded. These recordings are different in many respects than “classic” alleged sasquatch vocalization recordings, as well as being of considerably higher quality and because of that, we hope to find other areas where this is occurring.
Secondly, given that the end goal of most research is geared toward one or two common objectives (i.e. individual sightings or bringing in solid proof), we feel that as researchers we do have a degree of responsibility to share what we can -- to compare notes, so to speak.
We need to state very clearly that site location and integrity, as well as the anonymity of the landowner and that of his family, must be strictly maintained. The landowner is extremely concerned and guarded about his and his family's privacy, to the point where we all have signed confidentiality/nondisclosure agreements with him. While he more recently has become interested in knowing if anyone else has experienced similar events to these, his desire for privacy, and the integrity of the site, must remain our highest priority.
You'll hear several different types of vocalizations in these recordings, sometimes from multiple individuals, and often including physical interaction with the environment in the form of knocking on, breaking, and at times severe thrashing of brush and trees.
The recordings consist of screams, whoops, grunts, huffs, blowing, jabbering, very low guttural growling sounds, and on occasion extremely quiet "rumbling". Often, all of these sounds are heard in a short time frame. There are also several incidents of what sounds like loud tree breaking and knocking. At times, it seems apparent that this is in direct relation with the vocalizations.
On each event page we include a report of the time surrounding the event, as well as a highlight of the event itself. We also have separate individual sounds highlighted.
The recordings are best listened to through either very good quality speakers, or preferably good stereo headphones with the volume turned well up, and bass at least half way. You'll hear the loud vocalizations either way, but the difference between speakers and headphones is significant; you'll hear much more detail with the headphones. You need the volume and bass up to hear the lower, less obvious vocalizations.
As for analysis, we have had wildlife biologists as well as ornithologists listen to some of these recordings, and none have come up with a source animal.
Two respected university bioacoustics laboratories looked at the recordings and in both cases no matches to known wildlife were found. Several individuals, ranging from wildlife biologists to faculty members in multiple major university bioacoustics labs, have offered opinions based simply on hearing the recordings (or sections of them). These opinions have ranged from human, to canine, to "cat-like," to possibly grey fox. In the end there has been no consensus at all, which helps demonstrate the unusual nature of these recordings, particularly given the apparent physical aspect of many of the recordings (the tree knocking in particular).
An attempt was made by one of the major acoustic labs to completely rule out humans based primarily on the range of the more pronounced vocals, but this proved to be impossible as at least the louder vocals fell within an acoustic range overlapping that of human capacity. The recorders we use are optimized for levels within human hearing range (thus effectively eliminating sounds much above or below these levels) and they also compress the sound by removing the same areas (outside of human hearing), thus they are not ideal candidates for analysis.
We understand that these recordings are not proof of the existence of unclassified primates in North America. We neither intend to portray them as such or expect others to take them as such. From a scientific standpoint, they are simply recordings of "something" in the woods. Nevertheless, our experiences over the course of several years have led us to the strong personal suspicion that these are the real thing. While we are simply not at liberty to discuss many of the reasons we feel this strongly, and for many of us the strongest "evidence" is personal experience, we can offer these in part:
- There is an extensive history of reports at this location and in the area, many of which have been confirmed in one way or another. This history includes both multiple generations of the host family as well as several independent non-related events. Event descriptions stay true over years of interviews.
- The geography, timing and apparent source location of many of the recordings renders the possibility of a hoax from the outside extremely unlikely.
- Several of the events have included multiple vocal sources, both in close proximity and at fairly long distances, and while several of the "voices" have become familiar, there are often new or different vocalizations or voices involved also. This would seem to require a large network of both established and new hoaxers playing out predetermined roles, often on little or no notice, over a period of many years, and would certainly increase the likelihood, over time, of their being caught.
- We've effectively and to our satisfaction ruled out all family members as potential sound sources; they have many times been present during the events or otherwise accounted for. They’ve all seen us jump and run toward sounds and dark shadows, and thus they are aware of our potential to catch a hoaxer.
- The family knows that we deploy a number of game-cameras and change camera locations frequently without their knowledge. This has never been a concern with them.
- We have been given free reign with regard to research methods and utilization of the property. No research constraints of any type have been placed on us. We are welcome at any time with no advance notice, and have been encouraged by the landowner to make every effort to discover and disclose any evidence of a hoax. To date we have discovered no evidence of hoaxing in any form.
- There have also been fairly clear tracks and trackways found.
- Two of our members have had sightings through night vision of something very tall, dark, and massive in close association with vocal displays. Two other team members had a nighttime sighting, close to the campfire light, without night vision in the summer of 2008. One team member had a daytime sighting in the summer of 2005, and another team member had a recent nighttime sighting in the highbeams of his vehicle in July of 2009.
We have acquired these recordings with as much objectivity as possible and are releasing them in the spirit of sharing data; we hope that this gesture is received in exactly that way. We know this could be controversial, however we ask that those of you familiar with the people involved please keep in mind our demonstrated levels of skepticism, and understand that we employ the same level of critique to our own evidence and experiences as we have historically done elsewhere. Despite some very compelling events, and being incredibly excited on numerous occasions, we have been very conscious about not making assumptions or coming to unwarranted conclusions.
While we are willing to answer questions directly relating to these recordings to the best of our abilities, this is an ongoing research project and currently only the recordings are up for discussion. We cannot disclose additional information at this time, nor can we discuss or disclose information pertaining to other aspects of the project. We apologize in advance if we cannot answer a question related to subjects outside of the scope of our initial release.
Thanks again, and we hope these recordings may be of some help and interest to our fellow researchers.
