Many primates are cryptic, meaning that they have an incredible ability to hide from threats. But just because they are not seen, does not mean they are not heard. In 2007, State Wildlife Veterinarian, Dr. Briggs hall had an interesting encounter in California. While hiking in the woods, he heard two whoops in the near brush. Dr.Briggs has worked with large animals for over 14 years, and is very familiar with the species in the area. He explains that such whoops are solely primate in behavior, and could not have originated from any other animal in his region. He argues that the amount of sightings and especially, sounds described by witnesses cannot be ignored.
Voice recordings of the creature have been heard for hundreds of years. Greg Stutchman, audio forensic analysist, reviewed such recordings, removing outside noise from the actual howls. He sent the three of them to Dr. Joe Fox, Professor of Biology at Texas A&M University for analysis. The three separate Bigfoot recordings submitted to Dr.Fox all related in that they had a frequency of about 700 Herts, indicating a very tight pitch. Dr. Fox reported his findings within the three recordings submitted. The first, an elk, the second, a coyote, the third, a mysterious sound. The third recording does not resemble any recordings of animals existing in the area. Could it be a Bigfoot?
