The last two seasons, I have called in as many bobcats as turkeys...
They are interesting critters. I was sitting on a fallen tree, and had one jump up right on top the tree... He scared me, and I scared him... He walked to the end of the log and watched me for a bit, apparently unconcerned, but curious as to how I was making those turkey sounds.
We also have mountain lions, and that little situation has made me choose spots where no critters can come over the top of me. Mountain lions are also the reason that I load my gun walking out before shoot time... Prints all over both ranches I am hunting this year.
I had a motion hen decoy back in the day, and had a bobcat attack it... when he hit that hard plastic decoy it startled him, and he jumped straight in the air and took off...
Called in a red fox this year as well, which are supposedly not all that common in California...
Oddly, I get some satisfaction from calling in the predators... Called in more yotes than anything, but bobcats come in second, with three foxes (two greys and a red now). As close as they have come without me seeing or hearing them, I would guess that bobcats are probably the biggest turkey killers out there. I usually do not see them until they realize I am not a turkey.
