Here at NWM, we love the sound of birds in the morning and watching chickadees enjoy their breakfast on our bird feeder. Some birds such as pigeons, however, enjoy hoarding en masse only to defecate on things like buildings, vehicles, people, and HVAC systems, just to name a few. Bird fecal matter can be highly corrosive which can cause structural damage, even in materials like steel. The feces can also be harmful to breathe and can become an issue when dropped directly into HVAC systems. Other birds like woodpeckers like to put holes where they don't belong, i.e. the siding of your home and some birds like seagulls can be extremely protective of their nesting sites against animals and humans alike. Whatever your nuisance bird dilemma is, we have a solution for you.
