As America celebrates its 250-year anniversary, the Liberty Bell pavilion in Philadelphia is hosting millions of people from across the country. This approach also preserves a key feature of the structure’s design – the ability to easily see the Liberty Bell through the building’s windows. As a result, more than 1 billion birds are estimated to die from building collisions each year in the United States. Homeowners and businesses can also install bird-friendly window treatments to reduce bird collisions while maintaining clear views through their windows. Bird-friendly building practices gained momentum in Philadelphia following a devastating 2020 mortality event in which up to 1,500 birds collided with skyscrapers in a single day.
