Some believed the Bukwas remained in the mountains most of their time, and they would only come down once in a while. It is possible that the animal would use the dark period of the Moon to carry out major hunting. Perhaps to replenish food caches. This period would begin two or more days before, during and then, also two or more days after the New Moon. A seven to ten-day period. Back in 2013, Doug and I heard the most unusual howl, three nights in a row. The 8th was the New Moon. It is possible that the howl we heard on each of those three nights had to do with hunting.
Remember, the animal does not want to be seen and will do whatever it takes to remain hidden.
Note: Thinking back to the howl those three nights. It was long and unbelievably drawn out. As if it was in anguish too. Like maybe someone never came home. Or someone died and they miss them. A Growl, to a howl, then a scream. I heard a tinge of human between the howl and scream. That is when it really hit. I got the chills!
