We're hijacking the thread now, but...
I think it's rare, but - five coons in the pics before this one, feeding for a while.
Didn't get a pic with a dead coon in a coyote's mouth, but about 30 minutes later, four coons came back and stayed another 30 minutes.
Certainly not conclusive evidence, but I don't rule out yotes eating an occasional coon. I wish they would eat more of them though.
I've gotten other pics with yotes and coons in the same frame, seemingly getting along, so maybe the one above was just having a bad day.
