Nope...nor can I Brett.
I've always hated the way they go through a cornfield cleaning it up and taking away from deer, turkeys ducks, geese, rabbits, squirrels, etc.
I guess they got their place though, otherwise they would not be here.

Scott ,Good luck with making a state take responsibility for anything.LOL
This theory was raised about a farm in Canada years back. As I understand it the owners were trappers who would go out on the trapline for a month at a time. Before they would leave they would leave a huge pile of feed for their deer (and birds)to get them through the month. The birds would feed off of an infected wild carcass and then go to the pile of feed and spread the disease.
Since they were trappers I would assume that they had trapped all the carnivours around their area. So there wasn't anything to clean these cacasses up fast except for birds.
I believe that coyotes are friends to the deerfarmer and clean up diseased dying and dead animals. I for one will not shoot one.

Unless you bury the carcasses or digest them in acid the crows are going to find them no matter how many carnivores you have roaming around. It only takes a single beakful to do the deed. Besides what research shows coyotes don't spread prions?? This could be merely the tip of the iceberg when it comes to prion movement between hosts.
The more a coyote eats the fewer birds that are getting a beak full. Once the coyotes find a carcass it will only take a couple days for them to clean it up. If there aren't any coyotes around that carcass will be there for weeks. Hundreds of additional birds will have the opportunity to get a beak full. Migratory birds could spread it all over the US.
I don't know of any research with carnivores passing prions through their digestive tact. Could it be that a bird passes it through its system to fast to break down and kill the prion?

"Thus, there is little evidence to suggest that the crow digestive system would eliminate PrPRes infectivity prior to excretion of feces. Similar arguments can be made for nonruminant mammals because of similarities in endogenous enzymes in vertebrate digestive systems "

Above is directly from from the article.
Canines have a very short digestive tract which is mostly for protection from food poisoning, but would make them the mammals most likely to pass prions.

I have crows in my pens daily, but I have never seen them on the feeders. They love Deer poop. That's what they do at my place, clean up the crap......but if they can spread disease, I guess I'm goin Crow huntin'.
Just finished reading a formal study where the American Crow - if fed "CWD" type diseased animals (lab study was mice with mouse-adapted "CWD"). The crows were fed "CWD" mouse brains and then their feces were fed/injected back into new mice.... all of the new mice got "CWD". The study goes on to say the territory of an American Crow is 50-80 miles and a digestive tract of 4 hours. The study isnt to blame the crows but to show how any scavenger with a large territory does NOT break down the prions in digestion and in theory, could transmit CWD.
Sidenote: Found another article where doe urine may be banned in hunting as possible way to transmit CWD over many miles.

Read that also. If they say urine can be a vector then why would they not be able to test the urine of a deer to see if cwd is present?
Sounds like something the qdma jokes came up with!
