|Red bellied Woodpecker|
Sometimes, woodpeckers will peck hard on a metal part of a house. They've found that their noise is amplified greatly. This happens early in mating season and marks a territory.
Very rarely, woodpeckers may be creating a nest cavity. Although quite rare, it can cause serious damage. Fake owls or snakes don’t work at all. They don't move, which is what scares birds away. Save your money.
