Tim Sermons and Bob Truskowski are in the process of writing a book and they sent me a rough draft to review. This is a small snip-it discussing behavior:
“The gorilla was thought to be a myth until around the 1902. There were stories of large hairy man like creatures that would chase people out of the jungle. In the grand scheme of things this is not a long time to have existed, so to speak. The human arrogance is amazing even in these modern times. The gorilla is a very unique animal in that their characteristics are similar to humans. They are able to walk upright or crawl. They have a social organization and family groups. They feed and raise young. The behavior that is of interest is the behaviors that are similar to purported Sasquatch reports. This is the area of focus for this paper.
Gorillas are known to have approximately 22 vocalizations. Some of these vocalizations can be found on the Philadelphia Zoo website. The vocalizations range from grunts, roars and whoops; to snarls and teeth popping. The importance of these vocalizations to the research of Sasquatch is paramount. This is due to the fact that these same vocalizations have been attributed in the United States to purported Sasquatch recordings. There have been people who have inquired; “how do you know Sasquatch makes these sounds?” The short answer is through witness reports. There have been people who have reported seeing these creatures make these sounds. Refer to BFRO report #8547. This report discusses a hunter watching a Sasquatch kill a hog and whoop into the woods and then gets a whoop in return. Gorillas are known to do this to locate each other, but in the case of gorillas they are social creatures and never stray too far away from their immediate family group. Gorilla communication is more common in close proximity to one another.
Gorilla threat behavior is quite different. When gorillas are threatened they beat their chest with an open hand, they break vegetation and bluff charge the opposition. This behavior has also been seen in Sasquatch reports. In research areas throughout the United States, these behaviors have been reported and that tends to demonstrate that these behaviors are ancient, ingrained behaviors. The same goes for the research of the chimpanzee. The chimpanzee is highly intelligent and they live in similar ways as the gorillas.
The behaviors of interest with the chimpanzee are the behaviors of wood knocking. It is well documented that chimpanzees will knock sticks or stones together as a warning or to locate others in their troop. This behavior is also reported by witnesses. A story about a hunter that walks in and hears wood knocks and an hour later has a sighting of a large upright walking animal. The question is: was the knock to warn others that a hunter was coming or was the knock a warning to the hunter? This question may never be answered. Needless to say, there are similarities between the research of primates and Sasquatch.”
