Coyotes kill woman on hike in Canadian park

I'm afraid of bison in that they are huge, dark, and totally unafraid to stand in the middle of the highway.  However absent collissions with cars, and I've never heard of a bison being agressive with a person.

When bison are spooked, they run. In a big herd. In whatever direction they're facing, which is frequently toward whatever spooked them. And they run fast, 40km/h on flattish ground. I've helped out on a bison ranch a few times. You don't mess with them.

Fair enough.

Near Pincher Creek a Bison killed a retired lawyer/oilman in August of this year.  He was out walking in the field and the Bison gored him to death.

Bison are harmless - I am sure what happened is that the Bison was attacked by a bobcat, and accidentally gored the guy while trying to run away.

Bobcats are bad asses.
