The Santa Clara Valley Audubon Society, the Sierra Club Loma Prieta Chapter and the Sierra Club Bay Alive Campaign invite you to our symposium on dark skies and bird-safe building and exterior lighting design.

The use of LED technology and energy saving lighting fixtures are bringing with them an unintended, yet pervasive and harmful effect: the over-lighting of our nights. The symposium will focus on the biological and physical effects of lighting up the night and provide strategies that guard our health and environment while providing safe and practical lighting solutions.

The speakers are global experts on artificial light at night, light pollution and its impact on migratory birds, and solutions to reducing bird collisions.
