through the years of studying, it's known that yotes in the southwest are a bit smaller. getting larger as they go more north. cold climates and good surroundings for them to thrive in help as well. 2 yrs ago i shot a 50lb. alpha that came to another male challange call. 3wks ago i started a female/male communication to listen to response and observe initially,within a couple min. move to a rabbit distress. "the whole stand took maybe 7min." and in came another big male.48lb's. as soon as i figure out how to use a computer ill upload the pics. i was just curious the range in sizes elsewhere. by the way these 2 are the largest ive come accross but many others not far off.
