My house faces west so it gets full sun most of the day. I have a storm door that has a heat rejection film ( gila platinum). This film makes a slight mirror image when in front of it. I have 2 crows that will not stop pecking it, all day. I have tried scaring them off to no avail. I don't think they can hurt the glass, but they are pooping all over the stoop at the front door. Normally i don't like to kill things for the heck of it. But i don't see a way around getting out the shotgun. I need the heat film on the door to keep the front door from getting too hot. One of the previous doors ( it was metal) got so hot you could not touch it , and the insulation would melt and leak out around the small door window. This is a fiberglass wood look door, and i don't want it getting hot either, so the film stays on the storm door. Any options you see other than shooting them? My wife is not going to let me put a fake owl or anything like that. We have an outside cat, but she does not stay at the front door.
