There was one a good while back up around the Paso Robles area. No more. A rancher around the Bend, OR put up a bounty on coyotes a couple years back. He put up 15-20 grand (10 bucks a piece) thinking it would last a good while. It was gone in just a couple of months. I have a client with a 40,000 acre cattle ranch up there and his hands shoot the things like there's no tomorrow. After two years of this, they're finally starting to make a dent in them (mountain lions are still a problem, though). I hunted deer up there a couple years ago and they were all over the place.
The county where I grew up, Bland County Virginia, used to have a $100 bounty on the yotes when they first started showing up.... when they ran out of money they quite. I think there is a couple of counties still around here though that have $50 bounties.
Bounties are almost completely innefective in managing coyote populations or individual problem animals. You will not ever see bounties approved by the state wildlife agencies simply because they are a waste of funds. Consider that during the high fur prices of the 70's-80's coyotes expanded their range and the population increased. That in the face of high harvests.
