Lights Out Philly

April 1 - May 31

August 15 - November 15

Why
Lights Out

Each year, tens of million birds pass through Philadelphia during the spring and fall migration. Unfortunately, many are killed when they fly into buildings, confused by artificial lights at night or by reflective or transparent glass surfaces. Artificial lights at night can attract birds migrating at night to buildings and ultimately cause them to collide with other parts of the buildings associated with the lights.
