"Interesting. I've never seen an agressive coyote, unless it was rabid. They've all run at human contact.
That's my experience here in CA too"
I had an interesting experience about 20 years ago in upper Wright Lakes Basin in Sequoia NP. I was day hiking on a solo backpacking trip, came up over a rise, and found myself face to face with a group of 6 coyotes about 25-30 feet in front of me. I froze and they froze. After what seemed an eternity(probably 15-20 seconds or so), during which it occurred to me that the odds were not in my favor, the alpha male gave a low yip and the whole group trotted off very slowly at an angle and disappeared down over the rise I had just come up.
I had previously thought that coyotes were solitary critters, but there they were. Had they chosen to attack, I was meat for sure, but they seemed no more interested in
me than the wild flowers scattered about. Still, it sent a chill down my spine.
That night they sure put on a show for me. What a symphony!
