Billions of birds die each year from human-made causes. NVBA, Loudoun Wildlife Conservancy, Nature Forward, DarkSky NOVA, DarkSky Virginia, Friends of Dyke Marsh, and Friends of Little Hunting Creek have formed a partnership, Bird Safe NOVA, in an effort to reduce the devastating toll on birds from excess light and window collisions.

All migrating birds are at risk from excessive outdoor lighting each spring and fall. Some cities, including Washington DC, have established programs such as Lights Out DC, which works to convince building owners and managers to adopt light abatement procedures for the sake of migrating birds.
