Philadelphia to dim lights to make it safer for birds in flight

The lights of Philadelphia might not shine as bright in the coming weeks as a coalition in the City of Brotherly Love tries to prevent millions of migrating birds that pass through twice a year from slamming into skyscrapers and crashing to the sidewalk. Bird Safe Philly on Thursday announced the Lights Out Philly initiative, a voluntary program in which as many external and internal lights in buildings are turned off or dimmed at night during the spring and fall.
