You have a bear. Specifically a black bear. They're the smallest bear in North America (90-280ish pounds) and are smart....can even manipulate things. Make sure food is cleaned up, stored in containers in the garage with everything closed. Windows should be closed also. Any easy access food is a bonus. Easy food: chicken feed (or a chicken sleeping out), dog/cat food, trash can contents, etc. If you have a plastic dumpster with a flip open lid, keep it inside the garage except on trash day. A bungy cord over the lid is easily cut with those claws or teeth. The claws are 1-2 inches long.
This time of year, they're looking for places to den up to hibernate for the winter. Something to bear in mind (no pun intended), is that in warmer areas, they may NOT hibernate during the winter.
DS saw one climb over a guardrail on his way to work last week. First one any of us have seen in the 8 years here. At our previous home, 1 wandered INTO the high school. It also wandered out again. Kids stayed in class until it left the building, with adults monitoring from the other end of the hall. No one was hurt, including the bear. Respect the bear's space and it will usually do the same.
Typically bears are more afraid of people than people are of them. Make noise and give it space. Don't come around a corner quietly. As long as it hears you coming, it will probably move off in the opposite direction.
Oh, and black bears CAN climb trees (and other things). They climb very well.
