Sasquatch Ontario has released an audio recording that they captured on May 3, 2013 as part of their “Michigan Recording Project”. In the audio recording, you will hear what Sasquatch Ontario says is several Sasquatch vocalizations in addition to the well-known “tree knocking” characteristic of Sasquatch sightings. The recordings consist of screams, whoops, grunts, huffs, hisses, jabbering, very low guttural growling sounds, and on occasion extremely quiet “rumbling”. There are also several incidents of loud branch breaking and tree knocking that occur during the vocalizations.
The group stated that they provided the recordings to several biologists and two respected university bioacoustics laboratories who were unable to match the sounds to any known wildlife.
The audio recording is contained in the video below.
