I don't think there are bounties offered in any lower 48 states any more. That turned out to be a poor control method.
bounties are still offered in quite a few of the states most of the time they are too small to work the reason the beaver and wolf were almost extinct was because of how well bounties work .
I am a biologists that works on the production end that often regards wildlife as challenge.
Bounty system has been demonstrated not to be an effective control measure against coyotes although works very well on wolves. Former expanded range even when targeted by bounty system. Latter was extirpated.
Some species can be controlled / eradicated using bounty system. Most vulneralable are large with low reproductive capacity (ie wolves, bears, big cats) and those that are limited to specific types of habitat with limited home ranges (beaver). Others which are smaller like coyotes, foxes, coons and oppossums normally operate under persecution by larger animals so they have higher reproductive rates and greater mobility (often home range rather highly defined territory) . They also tend to be more adaptable in a landscape that changes from place to place in respect to threats and feeding opportunities.
A biologist concentrating on ecosystem management with wildlife as their first concern could give a more detailel / accurate assessment of how various predators respond to control measures.
