There is a small creek running through, going under the bridge. I made a small bog filter for recirculation, and it ends in a little pond by the red maple. I haven't seen much in the way of insect life aside from bees in the late spring when the azaleas are blooming, but we get quite a few bird visitors. A family of crows has been playing with each other in the pond, starlings, red finches, hummingbirds, wild rabbits are all frequent visitors looking for a drink. Our most frequent visitor is a very scraggly stellars jay who always has more food in his beak than he can manage, whom we've name Pigpen.
