Like I said in my first response Mercy, "kinda sorta know". It's more along the lines of what they have learned and how much pressure is on them as well as human population densities and all that sciency jazz. While no they are not geniuses, they are MUCH smarter than most like to give them credit for. Them getting "call shy" actually DOES show that intelligence. In the eastern part of the country, yotes are much more "shy" and wary than your western dogs. Unlike the idiots we have here that will come to just about anything any time because they have little to no fear of humans. Yotes around here make a fence post look like 185 IQ genius! But them Eastern dogs actually seem to be much smarter. Docs tend to spout off about what animals can actually think or not think but in all reality they have absolutely NO clue whether or not they do have logic centers. My feelings are, if they learn about calls and get wary of them, they have a processing center of SOME sort which leads to more intelligence than given credit for by most. I've been hunting yotes from both ends of the country and in the middle for a lot of years and seen some pretty dang sure signs of higher intelligence over them years. Just like Bears know when the Samon runs should be starting, yotes know when they should be seeing Fawns dropping.
