Jackdaw and veggies

The keep used to have a moat and drawbridge. The former was drained and the latter turned into a proper stone bridge. What to do with the moat? How about have a few brown bears as a sort of mini-zoo for tourists’ amusement? They’re fed veggies and things, which of course the local jackdaws think are theirs. I mean, they can’t eat enough to starve the bears, so I guess everybody’s happy.
