Birds in my Belfry

For most people it's bats. Tonight, for us, it was birds. Well one bird. Came home to a noise in the furnace room. Tracked it down to a little bird coming out the vent pipe above the hot water heater. The wife and I caught him and set him free. 20 minutes later the same noise was coming out of the same area. A few minutes later the little bird appeared. We caught him again and put him in a box. Hopped in the car and drove a few miles before letting him go. With any luck we won't see(hear) him again.
