A few brief comments and opinions, all related to field work in the Southeastern States. 1) The assumption that Bigfoot has to "find" a knocking stick to respond to other's knocks is a little misleading and many times erroneous. They very often carry a club with them while hunting AND foraging around home sites on which outside dogs are kept. They have been seen killing both pen raised and feral hogs, by the use of clubs. In WV and central AR they killed, and arranged the bodies of dogs in X formations, at night. At a location in AR, the home’s residents routinely heard their two dogs “booger barking” about midnight. After they took in another stray hunting dog, the dogs begin barking one night and one of the dogs – they think it was the stray – ran out from under the porch and aggressively confronted the intruder. When that dog charged, the other two also ran out. The residents immediately heard loud grunts, three loud thuds, and the sound of a dying dog after each thud. The man of the house got up immediately, grabbed his gun, but would not open the doors because of deep growling and hissing sounds near the front porch. Within a minute or two, he heard the sounds of fast bipedal foot falls run across the county road and into the edge of the Saline River bottoms. When he then went outside with his light, he found the bodies of the three, stacked one over another, each crosswise to the one below it, The bodies were stacked against the native rock pier blocks under one corner of the porch; the section of porch under which the dogs usually lay. Their heads had been crushed, and the owner said a club had left a groove across the top of their heads
I believe the late Bobbie Short may have posted on her forum a report from North Arkansas which I investigated and wrote about in which a young man saw a Bigfoot carrying a large club as it passed below his second story bedroom window on a bright moonlight night. The families’ outside dogs were huddled against the screen door between the front porch and living room. The BF was on the way to the family’s chicken pen.
2) During the hundreds of nights I have spent in BF hunting/foraging areas, I have NEVER heard ANY kind of bird or domestic fowl that could make a sound that could be mistaken for a Bigfoot signaling another of its kind using tree or rock knocks.
3) It definitely makes a difference what species of tree, and the type and condition of the limb used when BF or humans use tree knocks as far as the travel distance of the resultant sounds are concerned. The tree choice depends on the habitat of course. From blackjack oak in the mountains, to hollow cypress in the wetlands, or recently dead tree of any kind, it’s Bigfoot choice. For a creature that has the ability to break the top out of a good sized tree, a good solid four inch thick and four feet long knocking stick or club would literally be a “snap”.
