I don’t know if Colorado has Grizz- i think so- but not sure- Black bears can turn predatory too when food sources aren’t good- every now and again there will be starvign bears that get too close to folks and have to be relocated- but yeah, attacks are pretty rare-
Oh right, I had forgotten about those troublesome bears in the Sierras that were relocated. They weren’t necessarily predatory, but typically learned how to break into buildings.They had orange marks on them.
Unfortunately we knew if we reported one of those bears, they might not make it out alive the next time
