Black bears around here are not dependent on humans. They have an abundance of habitat on the mountain (I'm located on the foothills of the mountain). It was just probably a opportunistic thing on a pre-spring journey. I’ve been feeding the birds for 20 years now and have never had an issue with bears before. Whitetail deer, yes, but not bears. But if it returns I'll stop feeding the birds for a time as I couldn’t afford to keep buying new feeders.
Once, about 40 some years ago, I was fishing at a lake on the bank. A black bear came at me from the woods. I had no place to go but into the water. It apparently wanted my fish, grabbed them and took off.
