I spent my time in the shower this morning considering the only known predator of the buffalion of Kansas II. It is, of course, the so-called "trap-door weasel," actually a very large insect that lives in "cities" of pit burrows the stretch across migration routes of the herd omnivore. They are hunted in a manner very similar to the way prairie dogs are hunted on the Great Plains; similar, but not quite the same.
I may have to explore this in greater depth over at I Work On A Starship. Hoping to post an update in the current story arc before too long, too.
