The wife and I had an interesting few minutes this afternoon. We came home from work and heard all this scratching from inside the stove pipe by the damper, a bird had gotten down inside the pipe and was stuck on top of the damper, so I open the damper and wiggle it back and forth a few times and shazzam there's a sparrow looking at us through the glass. Well I go get a couple of my fishing nets and we try to catch him through the crack in the door, no workee, loose bird in house. Finally catch it and put it outside, congratulate ourselves on a job well done, look at the stove and there's another one in there, here we go again. caught the second one after about 10 min. chasing it around and let it go, maybe removing the screen on the cap wasn't such a good idea after all. Oh yeah, I thought the pipe was clean too, there's a pretty nice little pile of ash on the baffle now.
