Good discussion. I have personally witnessed one live interaction between coyotes and a bobcat. I was calling predators at night, and had a bobcat come across a wide open pasture for a 1/4 mile. As the cat got within 150 yards, I noted a coyote coming in hot on the same track the cat took. Now, was the coyote after the cat? Probably not... He was more than likely responding to the call, just like the cat.
However, the coyote was coming faster than the cat, and soon the two would meet. When the bobcat got about 100 yards out, it looked as if he suddenly was aware of something following him.
The coyote was about ten yards behind the cat, when the cat suddenly spun around to face the coyote. That cat puffed up his hair, raised a front foot, displayed his fighting knives, and growled. The coyote threw the brakes on, skidding to a stop.
For a brief moment, I thought I was fixing to see one hell of a fight. But it appeared the coyote started second guessing his actions. You could almost see him thinking "Oh crap! What have I got myself into?"
The guy with me was running the light, and holding it steady on the bobcat. thinking i was going to shoot the bobcat. They were almost in the same line of sight, through my scope.
Thats when the coyotes second thoughts became a reality... A 45 grain bullet struck him dead center in the chest! HA HA!
That cat stood there for a couple of seconds, thinking he had scared that dumb coyote to death. Then he started to trot off to the right. My buddy running the light kept folowing the cat. What he didn't see, was the second coyote coming on the run back behind the cat. I had to tell him to swing the light left.
Now, I would like to end this story by telling you how I deftly killed both coyotes, sparing the big bobs life... But that wouldn't be true. I took a running shot on the second coyote, as he was skinning out like his ass was on fire when he stumbled upon his previous hunting buddies carcass, and I missed.
I let the cat walk... this time (it was early in the season, and they had not primed up yet).
Since then, I have always wondered... What would have happened if I hadn't shot the coyote???
My best guess is that big 'ol bob would have wooped that coyotes ass! At least until his buddy arrived. Even then, I don't think the coyotes would have prevailed.
Just my thoughts.
