In my experience, going back to the mid 60's and coming forward to present day, it has gone from being rare to a very common happening. I wish everyone could experience those first dozen spring gobbler seasons.My Dad was pounced by a bobcat about 20 years ago in Tioga Co calling turkeys. He had crawled up to a field edge, was laying on his belly calling to a flock of birds out in the field. After a few soft calls he knew something was behind him. As he slowly turned his head the bobcat pounced, his mesh face mask likely saved his eye.
I started tagging along with my Dad and uncles turkey hunting at a very young age (5-7) in my 20+ springs of turkey hunting I have seen 4 legged predators called in almost every spring. Most frequently gray fox, but maybe 5 coyotes, a bobcat, several bear etc. In my experience it is not happening anymore than it did 15-20 years ago.
