First, momma Barred owl flew to this hole. I’m not sure if she was using it as a cache or checking it out as a nest for next year. One of the kids saw this and after momma left, went into the hole to check things out.

After rummaging around a bit in it, he emerged with this tasty piece of bark. We were so excited when it happened because we thought it emerged with a mouse until we looked at an enlarged image.
