My parents had a problem with a bird at their house. It kept shitting all over near this one window and this wall, and then it kept flying into the window and falling down into its own shit and tracking it everywhere. Apparently the retard thought that the reflection was another bird, and was trying to fight it. Anyways, I told them to get one of those plastic owls from Lowes, I had to get the same thing when some geese kept coming around my place. The bird stayed away, and started at some other windows, so they just got some window decals of eagles and vultures and now it doesn't come back.
