I can tell they're liberal because I'm calling them in with a hurt rabbit squall and they think they're getting a free meal.
I'm sorry but I was so proud of that answer I had to turn it into a regular post - way too good to be buried in the comments.
It's true though, I think I've only shot one coyote in my entire life that I hadn't called in and that poor thing was staggering down a dirt road in the middle of the day out of his mind with hydrophobia. I put it out of it's misery with my 41 from 2 feet away.
But yeah, I'd say 95% of the others were shot using a wounded critter call. A couple with howling but mostly rabbit or fawn squalls. Easy meals for the liberal coyotes.
