At least our chimney is pretty much at the other end of the house from the bedroom. I have thought about putting some sort of padding up on the chimney cap, but then they’ll drill holes in the siding.
I tried two plastic owls this spring. One’s head is on a swivel spring and moves in the slightest breeze. They are below the top of the chimney on top of our pergola. They worked for a couple days, then the woodpecker wised up.
I need to hire somebody to install bird spikes up on top of the chimney. The top of the chimney is about 35 ft off the ground and the roof is a 12/12 pitch! Not easy to get to. Just need to make my insurance coverage is good before letting a guy work up there.
