February 15 through May 30 is Lights Out For Bird Migration
People are asked to turn off or dim the lights at night in tall buildings like the ones in downtown San Francisco and Oakland.
More than 250 species of birds migrate through the Bay Area each year. Many of them fly at night, and can be disoriented and drawn off track by bright urban lights. Sometimes they crash into buildings; other times they circle lighted buildings until exhausted and easy prey for predators.
